As an aside, there was some time in the recent past where blue antireflective coatings on eyeglasses were popular. I actually had to make a special request for the old purple/green coating for a few years, because the blue reflections were so distracting while working in an office with overhead fluorescent lights. Many years have passed since that trend and modern coatings seem more blue-ish than purple/green, but they aren't distracting at all. I'm actually shocked how little light modern lenses reflect at all.
- anon84873628 3y agoI didn't understand how people could claim they have "blue light blocking glasses" with clear lenses. I can literally see the blue light coming through it! I think Gunnars was early to the market and they actually have amber tint. Before that I would buy amber tinted safety glasses meant for working with lasers. I still take these on trips if I'm staying somewhere unfamiliar... You don't know if the place is going to have hideous harsh blue-white LEDs. Fortunately most places have figured out the need for comfortable warm lighting. All the computer operating systems have a built-in night mode too. I stopped short of putting an amber film over the Kindle...
- EA-3167 3y agoI have some blue-light blockers which I use only in bed, when reading before going to sleep. They are bulky with 'side boards' to block light, and they turn everything into a sort of orange, undifferentiated hellscape. The upside is that they seem to work, the downside is that it really only works if you're at a point in your day where you're ONLY looking at text.
