18-year-old built a computer monitor that doesn't strain your eyes
- kazinator 3y agoThe nice thing about this is that: - the backlight lamp is a point of failure in monitors; good riddance. - if you want this thing brighter, you just supply brighter illumination.
- CharlesW 3y agoI lol'd at this line from the Indiegogo campaign video: "Eazeye has a built in LED strip so it can work in the dark." So, I guess all I need to do is mount aquarium lights directly above my monitor to get an extremely dim image during the day? https://images.fastcompany.net/image/upload/w_1200,c_limit,q_auto:best/wp-cms/uploads/2023/10/10-90971739-low-light-computer-monitor.jpg https://images.fastcompany.net/image/upload/w_1200,c_limit,q...
- tokai 3y agoAn incredibly bad idea to me, but great if it works for some. Will definitely keep an eye on reviews for it. Also as it always is with these young-person-creates-a-company stories: «Huang’s parents, who run a metals recycling business near Shenzhen, China connected him with manufacturers in the region.» I wonder who payed for the first production run.
- pipeline_peak 3y ago> I wonder who payed for the first production run. Are you suggesting the kid pay for it himself?
- mjburgess 3y agoHe's suggesting that the reason we find child-inventions impressive is because they're children doing it. "Rich manufacturing-savvy parents fund child's idea" is far more par-for-the-course. I'd imagine it would be quite routine for children to "invent" things with such parents --- how many are tinkerers as children? A lot.
- dotnet00 3y agoI think the point is just that more often than not, the kid is only where they are because they happen to have someone else taking care of the bigger challenges that end up being the barriers for most other would-be young innovators. Kind of like how especially well done science fair projects or reports for very young kids are often the result of parents handling most of the intricate work or otherwise being engineers/scientists in the field themselves, thus being able to get them access to things typical kids don't have. Eg 12 year old me could only throw together a solar powered buzzer through trial and error with electronics as I had no one who could do anything beyond resistor networks, but my kids would be able to do much more advanced things because I would be able to handle/simplify the complex stuff for them. Another glaring example would probably be Sam-Bankman Fried. No way would any person without the connections offered by his parents have been able to get praised and handed billions of dollars by investors for playing video games while pitching to them.
- anon291 3y ago> I think the point is just that more often than not, the kid is only where they are because they happen to have someone else taking care of the bigger challenges that end up being the barriers for most other would-be young innovators. So what? If the child did nothing, nothing would have happened. He did something. It might be worthwhile. That should be celebrated. > Eg 12 year old me could only throw together a solar powered buzzer through trial and error with electronics as I had no one who could do anything beyond resistor networks, but my kids would be able to do much more advanced things because I would be able to handle/simplify the complex stuff for them. Which is why our emphasis on social mobility ought be at the family level. Families move socioeconomically. Individuals are just brownian motion.
- TeMPOraL 3y ago> So what? If the child did nothing, nothing would have happened. He did something. It might be worthwhile. That should be celebrated. That's the thing though. The kid could've done anything between something and approximately nothing, and you wouldn't be able to tell. It's just like with the science fairs - the especially well done projects sometimes are just 100% done by parents.
- tokai 3y agoNo. I am interested in if it is financed by investors that believes in him and the project, or his parents that might value supporting their child higher than putting money behind a good investment. In the end I don't know, I just couldn't help myself being a bit snarky cause these young entrepreneur stories always seem to come with some asterisk.
- watermelongunn 3y agoIt stirs great jealousy in me as well... but as they say, are we not all standing on the shoulders of giants? And if the new [whatever] is an improvement, does it matter if it came from a rich kid? Sorry, I'm not actually directing these questions at you, but rather myself as I try not to feel any resentment toward people who were born better off than me.
- AlanYx 3y agoOne thing I'm curious about... with the hinge closed, is this monitor functionally equivalent to an RLCD display (like SunVision's products or the Hisense Q5), or is there still a discrepancy in brightness versus an RLCD display in equivalent ambient light?
- jedberg 3y agoI appreciate this guy trying to solve his problem, but it sounds like what he really needs is blue shifter like flux or the built in systems of the OS to set the color temperature lower. I just have flux running all day cutting the temp to 5900K. Never had eye strain after that (and slept better too because I cut down to 1900K at night (ie. very yellow). If he has to use other people's devices all day, like school devices, he can always wear blue-blocking glasses.
- SomeRndName11 3y agoIt is a typical advice which is efficient but flawed. All software methods to change color temperature suffer from two problems: they kill contrast (already low for IPS), and they kill color calibration. It also cannot change the backlight spectrum in the blue area. Proper, good backlight won't strain your eyes, when run at normal 6500K temperature,as it has blue peaks shifted.
- progne 3y agoI wish the article explained why redesigning the monitor to use ambient light is better than turning down the "brightness" setting. Anyone know?
- CommieBobDole 3y agoBecause "hey, turn down your brightness a little, dude" is not a product you can sell for money.
- actionfromafar 3y agoHow about, turn the brightness up to match the suns? Can't do that very easily either. If anything, I think this screen should have the option of collecting ambient light from an even larger area. It's actually somewhat genius. It's also interesting with color temperature. I guess it's a CRI of 100 in day light?
- hu3 3y ago> How about, turn the brightness up to match the suns? Can't do that very easily either. My phone has a setting for that. And it's possible to do with a webcam + monitor: https://askubuntu.com/questions/23593/use-webcam-to-sense-lighting-condition-and-adjust-screen-brightness https://askubuntu.com/questions/23593/use-webcam-to-sense-li... There's probably some software for that.
- fwmcbumcrumble 3y agoI don't understand why more device don't have ambient light sensors built into them. Phones have been doing this amazingly for 15+ years but almost no displays do. I think I saw a TV a while back that did, but that's 1 out of the 10 billion models out there.
- FirmwareBurner 3y agoMy cheap Benq monitor has a ambient light sensor, and I disabled it because it sucks. It never manages to set the exact brightness I would consider right for me in every scenario. Instead I much prefer to control it manually via the mouse scroll wheel and DDCI, that way I can adjusted exactly to my liking every moment of the day. On phones this feature makes sense because as you walk and move around the ambient brightness shining on the screen changes rapidly but on a indoor PC monitor in a room/office, the ambient light is relatively stable because you can control it via light switches or window blinds, so manual control is fine.
- hn_throwaway_99 3y agoNot to crap on an inventive kid, but I don't get this. A normal LCD screen works by shooting a backlight (usually LEDs) through an LCD panel. All this project does is replace the backlight with either a reflective backlight, or ambient light if it's bright enough. So how could this be any improvement beyond just turning down the brightness on a plain old LCD screen?
- neogodless 3y agoI think it would make sense if screens detected ambient light and adjusted brightness to match (like smart phones do....) so this is just a clever way to do just that with low tech. But a high price. So yeah, I think it might just be better to take the existing technology in smart phones and apply it to laptop and desktop screens.
- lupire 3y agoMonitor screens do this, if you don't get a cheap one.
- FirmwareBurner 3y agoI have a cheap monitor with this feature and I think it sucks. It never manages to set the exact brightness I would consider right for me.
- deleted 3y ago[deleted]

- jfim 3y agoIt automatically adjusts to ambient light, which isn't common on desktop monitors afaik. I wonder if one could just replace the backlight by a mirror though.
- hex4def6 3y ago
- zwieback 3y agoDifferent but worse by almost every metric, what don't I get?
- rom16384 3y agoSome people get eyestrain from regular monitors, https://ledstrain.org/ https://ledstrain.org/
- amluto 3y agoWait, so instead of a regular screen, you get an unevenly lit screen and a very bright and glary light source that’s visible right above the screen? Those sample pictures look miserable to work near. How about a conventional display with an ambient light sensor that can adjust brightness to match the ambient conditions? Bonus points for optional automatic white point adjustment. (Many mobile devices have these features.)
- theGeatZhopa 3y agoNice one if you working monochromatic. Bad one, of you want to see colors. Nice one if you want it to be cheap. Bad one, if you have to use light sources, that use up more energy than the trad. Backlight. Nice one, if ... Game. What do you think of other pro and contra arguments?
- DistractionRect 3y ago> Nice one if you want it to be cheap. Suggested retail price $1099. At that point, I'll just buy an OLED and just turn down the brightness.
- theGeatZhopa 3y agoYou're right.. didn't realize, that $1099 is a bunch of money. Way too much for darkness.
- boplicity 3y agoOne of the things I really hate about reviews of laptops, screens, etc, is the focus on how bright the screens are as though it's a good thing. Who really wants to be staring at 1,600 nits of brightness all day? Certainly not me. A much better screen, in my opinion, would have super high contrast with low brightness. Yet, this isn't something that gets measured by reviewers. Coincidentally, that's also why I like using OLED screens. At least with true black, much of the light can get turned off completely.
- post_break 3y agoWhat? That's like complaining your car reviews talk about how it has 300hp, why would you be at full throttle every time you drive? High brightness is a good thing because it's used for HDR, areas where there is a lot of sunlight, etc. Something OLED struggles with as well. My wifes laptop with OLED only does like 600 nits.
- dijit 3y agoI think the parent has a point. We talk a lot about peak brightness, which is useful in some scenarios like you mentioned. But you know whats more interesting? Brightness stepping, min brightness and ambient light sensors; which are never talked about by reviewers, which is then a weird cycle because manufacturers seem to care a lot about what reviewers focus on.
- 1270018080 3y agoA car having unnecessary hp is a great example against your point.
- post_break 3y agoHelp me understand. When a car has multiple trim levels, and one has more horsepower, you would want the one with fewer? Because in theory you wouldn’t use it? And this has nothing to do with MPG either because in some cars the higher power engines get better fuel economy. But based on that metric alone, you would pick the lesser model? Just like if a MacBook Pro came in either 1600nits or 400nits, you’d pick 400? Yes or no?
- izzydata 3y agoI'd like to see a high refresh rate color e-ink display as a computer monitor.
- leafmeal 3y agoNo comment on this actual product, but I found that turning the brightness as low as I can tolerate on my monitor significantly reduced my eye strain and discomfort. It takes a little getting used to, but I highly recommend giving it a try.
- leafmeal 3y agoAlso using light mode instead of dark mode helps with visibility on a dim screen
- IYasha 3y agoBut only as long as it's not a freakin' PWM. I have this problem on my laptop and TV and anything lower than 100% hurts as hell. (
- SomeRndName11 3y ago95% of monitors on the market are PWM free these days,
- Sohcahtoa82 3y agoYou don't need a fancy monitor to not strain your eyes. You know you need? Lower brightness or more ambient light. This is something I've been saying for ages. Some time in the last 10 years or so, it seems we decided as a collective that screens should be SUPER BRIGHT, and now half the tech crowded uses dark mode. If you "just like dark mode", that's fine. But if you avoid light mode because it hurts your eyes, then your brightness is too high or you don't have enough ambient light. I sit at my computer 12-16 hours a day. Yes, I know, it's pretty unhealthy. But I have never felt eye strain. Even after getting LASIK and my eyes were a little more sensitive to light, I could stare at my screen all day after the first day.
- stronglikedan 3y agoI get eyestrain with lower brightness, but I typically don't use my computer in the dark. On the occasion that I do, I do lower the brightness. I also loathe dark mode in general, but I do enjoy a darker background with colorful fonts while programming (Dracula theme for Sublime). All in all, I rarely get eye strain with my habits.
- thomastjeffery 3y agoAre you experiencing the inverse problem? If your screen is darker than your surroundings, then it will likely strain your eyes. The goal here is to match your display's brightness (the content you see, not just the backlight intensity) to your room's ambient lighting.
- seemaze 3y agoExactly this, you should be viewing a monitor in the same lighting environment that you would read a book or magazine. The catch is physical media forces you to address a deficiency by changing your environment, where an illuminated screen allows you to adjust the media. Maybe I should wire the monitor controls on my computer to adjust the lights in my room..?
- thomastjeffery 3y agoThis is why I want neutral mode. The solarized theme went halfway there twice.
- dragonwriter 3y agoIf nothing else, this monitor is a good way to counteract the problems that come from working in otherwise-underlit workspaces, since it simply won't work there.
- bjnewman85 3y agoThis is a nice idea. But it appears the trend of "Look at this astonishing youth!", then in paragraph 8, "whose parents own a recycling company near Shenzen...and connected him with manufacturers" so this is a joint venture between his parents company and some of their friends to back their son's business idea. Very newsworthy.
- tobyjsullivan 3y agoNot sure how relevant that is. Anyone who does anything impressive will always be dependent on their support network. It is unfortunate that the most driven, intelligent person won't accomplish much if they don't have the network. But I don't see why that diminishes this person's accomplishments.
- jonny_eh 3y ago"No man is an island." Also, "If you wish to make an apple pie from scratch, you must first invent the universe" -Carl Sagan Nobody accomplishes anything of note alone.
- Gud 3y agoYes, but there is a difference between “18-year old”and “18-year old born into riches”. This also seems like a gimmick. In what way is this better than just reducing the monitor brightness using software, e. g with xrandr?
- _trampeltier 3y agoVery nice. Recently we spoke about monitors. Why don't office monitors adjust the brightness. I often just make light in the office, because it is simpler than adjust the brightness from the monitor. I know thats sick, bad, expensive, whatever solution.
- ecshafer 3y agoIt sounds like the issue is that there are too many Computers / TVs and screens in schools. For something that has no evidence its better for learning (And actually evidence its worse for learning). Perhaps schools should rethink things.
- criddell 3y agoWhat exactly is eye strain?

- Justsignedup 3y agoSo what he's saying is a monitor that adjusts brightness to ambient light like a cellphone screen solves the problem?
- ghostpepper 3y agoApple laptops do this too. Probably possible to rig up on Linux
- jcuenod 3y agoI'm pretty sure my laptop is doing this through something between Gnome + Arch without me configuring it (Precision 5560)
- PaulKeeble 3y agoWhat we really need is desktop monitors to have similar light following properties as tablets and phones and if that can be calibrated a bit they will follow the lighting of the room as it changes through the day. We don't need completely new monitors we just need desktop computers to copy something phones and tablets have been doing for 15 years now and all for the cost of a simple light sensor. Desktop monitors have not made it possible to adjust their brightness from the PC and that is a big problem in all this or we would have solved this years ago.
- withinrafael 3y agoActually, most monitors support the DDC/CI protocol [1]. But I think implementations tend to be spotty hence Windows (for example) doesn't show a brightness slider in some configurations. Third party apps exist though (e.g., TwinkleTray [2]).

- IYasha 3y agoFINALLY! Someone remembers! There even was a monitor remote control panel in NVIDIA Display CP in Windows 98 or 2000. It was awesome!
- jon-wood 3y agoMost monitors do in fact support this via DDC, but in general the OS doesn’t expose that to the user.
- eternityforest 3y agoWhy can't we software emulate this? We have webcams, we know roughly where light comes from and how much. We should be able to turn those sources into 3D model lights and illuminate a virtuall screen, perhaps even with onscreen objects having some texture, like raised. Button in browsers. Better yet, how can we get just away from screens more without getting bored? I love screens but there's a limit. Gaming and online content are pretty much the ,ain leisure activities that don't involve food or alcohol (and all the health issues of overeating and drinking). Seems like we used to do more other stuff.
- _chu1 3y agoDid CRTs cause more or less eye strain than LCDs?
- IYasha 3y agoThere were a lot of varieties of those. Some were better.
- SomeRndName11 3y agoMuch less to me. Due to more wide spectrum esp in blue area.
- thomastjeffery 3y agoEye strain seems like the wrong thing to focus on here. I'm much more interested in the efficiency of this design. Most of the energy drawn by an LCD goes into its backlight. If you are trying to use one outside, then you are fighting the brightness of the sun by matching its intensity with a backlight. Why not just use the sun as a backlight instead? Of course, this is a very simple and clunky version of that. I do wonder how much could be optimized.
- UtopiaPunk 3y agoI personally would like to see a resurgence and expansion of Reflective LCD screens, and this seems sort of similar. I mostly associate Reflective LCD screens with Gameboys. Remember how helpful it was to go outside to see the Gameboy screen? There was a reflective material on the back side of the screen, which "lit" up the screen. As an aside, there was even a cool Gameboy Advance game with a solar sensor that encouraged the player to go outside to charge up the protagonist's "solar gun": https://en.wikipedia.org/wiki/Boktai:_The_Sun_Is_in_Your_Hand https://en.wikipedia.org/wiki/Boktai:_The_Sun_Is_in_Your_Han.... Even the GBA SP, which had a light you could turn on and off, lit the screen up from the front. I'm definitely not an expert in the area. My impression is that after the Gameboy, there wasn't much demand for these types of screen. I also suspect something about them doesn't scale to larger sizes as cost effectively as other screens, and there's been little interest from corporations in improving the technology :(
- layer8 3y agoReflective LCD monitors exist: https://www.sunvisiondisplay.com/ https://www.sunvisiondisplay.com/ However, resolution is relatively low (FHD at 32”), contrast is quite low (25:1), as is color gamut (15% of NTSC). Still, some may prefer them over emissive displays.
- utopcell 3y agoNot to mention, quite expensive for the specs.
- hn_throwaway_99 3y ago> I personally would like to see a resurgence and expansion of Reflective LCD screens, and this seems sort of similar. However, this monitor is not at all a reflective LCD screen. It's just a normal emissive LCD, but which for some reason uses a Rube Goldberg machine as the backlight.
- jonny_eh 3y agohttps://play.date https://play.date I have one, it's kinda fun, but it's annoying to "find a light" to play near.
- Waterluvian 3y agoSomething that drives me absolutely bonkers is how laptops, phones, tablets, all treat brightness as a first class feature. But if you want to quickly adjust brightness on your desktop monitors, it’s intensely tedious or requires you to be tech savvy and install software. Why oh why can’t I just Fn + Fkeys to adjust brightness on the fly?!
- Archelaos 3y ago> Why oh why can’t I just Fn + Fkeys to adjust brightness on the fly?! On my Thinkpad T550 I can use Fn + F5/F6 to adjust the brightness.
- NooneAtAll3 3y agoprobably because software side still wishes for the buttons on the side of the screen (anyone remembers degaussing?)
- Waterluvian 3y agoI loved how the longer you waited, the more wacky the degaussing would be.
- LeoPanthera 3y agoI use "MonitorControl" on my Mac Studio to control the brightness of my Dell monitor: https://github.com/MonitorControl/MonitorControl https://github.com/MonitorControl/MonitorControl
- jhallenworld 3y agoIf you really want to help with eye strain, make a monitor with some kind of pancake optics so that the screen appears to be at infinity. Having to focus at something right in front of you all day strains the focus muscles in your eyes. Older people will know what I'm talking about here..
- winrid 3y agoSwitching from OLED to IPS screens that have no flicker helps a lot too. Very hard to find an OLED monitor that doesn't have flicker (this is not refresh rate - this is brightness modulating from 0 - 100% hundreds of times a second - hard on eye muscles). Old CRT monitors were even better than current OLED displays because the flicker modulation was a curve and not a digital hard/on-off type flicker.
- RadixDLT 3y agohe didn't really build anything, he just took out the back light
- LouisSayers 3y agoI always have brightness on as low as possible and have noticed people in the office often have theirs up quite a lot. Never suffered from dry eyes, at 36 still have 20/20 vision, and haven't felt a need to do anything about my monitors. The biggest issue I've faced is actually environmental glare (light from windows / bouncing off walls) - but nothing some curtains couldn't fix.

- adfgiopjionio 3y agoA dim, unevenly lit panel with awful color rendering is supposed to reduce eyestrain? This is good for winning first prize at a high school science fair. It makes no sense for any other purpose. And even at a science fair, the ability to build this is somewhat impressive but the inability to recognize it as a bad idea is not.
- ideasphere 3y agoSony released the PCG-C2GPS laptop in Nov 1999 which had a reflective LCD almost exactly like this. The use-case was that you’d primarily use it in your car (during the day) for navigation and want the better battery life by not having a backlight. The back of the LCD hinges off like this but also stores a front light you can attach for low-light situations. https://pc.watch.impress.co.jp/docs/article/991104/sony.htm https://pc.watch.impress.co.jp/docs/article/991104/sony.htm The photos of the screen in use look bad! B/W only for reflective in my experience (i.e. Pebble watch.)
- SomeRndName11 3y agoThe thing with eyestrain, that it is extremely different to pinpoint what it causes for people with sensitive eye, so any alternative solution would work. The most important factor is, obviously is the backlight, and not only being PWM or DC, but also the spectrum and "texture" of the light itself: a typical LCD has diffusers which may have different construction and cause serious issues for some people. Some may be sensitive to polarisation, some people are sensitive to how grainy is antiglare coating is etc. A good number of people (me including) cannot tolerate backlight with blue at 450 nm, the more it is towards green the better. Some cannot tolerate KSF phosphor in the wide gamut backlights (I am perfetcly fine with it), and love quantum dots. It is a serious problem, but using the ambient light for the backlight would make experimenting the backlight a super easy task, so yeah, this monitor is a great idea.
- esperent 3y ago> A good number of people (me including) cannot tolerate backlight with blue at 450 nm, the more it is towards green the better. How do you go about figuring out something like that?
- saeranv 3y agoI disagree with other commentators here arguing that there's no benefit this monitor would bring over simply reducing screen brightness. But I also think the claim made by the article here is at best, miscommunicated: that the bounced light improves the monitor light quality itself. On this point, I think the criticism from HN is correct, there wouldn't be a meaningful difference between equivalent bounced light, and light from the monitor. There might be a possible benefit from the lack of light flickering from AC-driven electric lights, but that is only true if the space is daylit. However, I think there is a quantifiable benefit from making the monitor light directly dependent on environmental light, which forces our perception to adjust to a more, low contrast, diffuse environmental context. Part of the problem is that "brightness" in the context of monitors is different from how "brightness" is used in science of light, where it is defined as the subjective perception of light that changes relative to differences in light levels[1]. So you can see your way to the washroom in the middle of the night with no lights, but can't see your way back after you turned on the washroom light, because your subjective perception of light (brightness) has changed, even though objectively the amount of visible light (illuminance) has not changed. Therefore, having a screen lit by the environment, would shift your perception of light to better see duller, low-light conditions, which is better for our eyes, since more uniform, diffuse light causes less strain than strong, directed light.

- jolmg 3y ago> There might be a possible benefit from the lack of light flickering from AC-driven electric lights, but that is only true if the space is daylit. The change isn't from AC-driven lighting to non-AC-driven lighting. It's the other way around. I'm seeing a regular AC-driven lightbulb above the screen. Monitor backlights are DC-driven.
- russdill 3y agoJust to be pedantic, they are driven by a pwm. But the frequency is orders of magnitude higher than 60Hz
- syndicatedjelly 3y agoI put a $20 lamp behind my monitor and turn it on when it’s dark outside. Works amazingly well.
- reactordev 3y agoIn 2007 I was taking apart LCD screens to do multitouch experiments. One of the things that I noticed was that without the backlight panel, you could light up the screen using ambient light and use a camera to get infrared light to reflect your fingertips for detection. A bunch of folks in the NUI space were doing this. Projectors, LCDs, front detection, back detection, capacitive touches, optical touches, etc. The biggest issue with this approach is color balance. Imperfect light creates imperfect colors. The LCD is tuned to display colors at the light intensity of the backlight panel it uses. Without the backlight and filters, light is uneven, unbalanced, and it will show in the screen. Fine if you’re just doing text. Not fine if you’re editing video. In the end, this is not a new approach to monitors but much much worse.
- biocross 3y agoWhy not just use https://displaybuddy.app https://displaybuddy.app on a modern monitor and not strain your eyes
- jasfi 3y agoThis is a great idea and I'd love to try one of those. If you need something for eye strain, try Lutein.
