Fake "science". Vitamin A deficiency most definitely can cause night blindness. In the event you suffer from a deficiency, carrots most definitely can address it. I have personal experience with this. I couldn't see anything at all in low light, so I took up drinking fresh carrot juice in significant quantities, and within two weeks it was like a dark curtain had been withdrawn from before my eyes.
I have doubts that eating a carrot a day would do a whole lot of good, but I can tell you that 8 ounces of fresh carrot juice a day definitely does!
- adventured 10y agoI gave semi high dose lutein (45mg per day) a try as I noticed my eyes weakening (early problems with long-distance vision, night vision). Helped substantially, took maybe two months to have a noticeable effect though.
- nitemice 10y agoWould you recommend this for people with established short-sightedness? I'm always worried about my eyes getting worse, and they have been, year after year.
- teslabox 10y ago> I'm always worried about my eyes getting worse, and they have been, year after year. Sometimes people's vision prescriptions are too strong. I started going to a 'developmental optometrist' about 12 years ago. While I don't see 20/20 with my current glasses, I tried stronger lenses from a conventional optometrist 7 years ago and found them intolerable. When he wanted to charge me for another office visit for the contact prescription, I just ordered the prescription I wanted from an internet contacts store.
- overcast 10y agoHow do you order from an online contacts store, without a valid doctors prescription? I've worn glasses since I was in kindergarten, and contacts since I was seventeen. Never have I been able to order contacts online, without a doctors prescription. They expire within a year typically.
- swedesford 10y agoNot all companies in all countries are quite so rigorous about checking for current valid prescriptions as others.
- detaro 10y agoIn addition, many countries don't have prescription requirements for contact lenses at all, so there is nothing to check.
- overcast 10y agoYikes.
- detaro 10y agoWhy Yikes? I mean, yes, contacts have a higher risk of getting infections etc compared to glasses, but that's not really fixed by yearly check-ups. And a pair of glasses can be good for 5-10 years if your eyesight is stable. I guess if you just start using them you'd want an expert advising you, making sure everything goes correctly?
- toomanybeersies 10y agoYep, never heard of needing a contact lens prescription to order them before. Here in New Zealand you can just order them online from Canada for cheap. So I suspect Canada is the same.
- Spooky23 10y agoLook around. Many sites let you just punch in the numbers. The downside is that you need to make frame adjustments yourself or go somewhere to do it.
- switchbak 10y agoIf there was some existing anecdotal reports of carrots/vitamin A giving you better night vision, I'd think it'd make an even better cover story than something more outlandish. Maybe in this case they just happened to accidentally cook up a cover story with a grain of truth to it?
- jimmaswell 10y agoAmazing that MI5's shills are still at it! (/s)
- teilo 10y agoI think the takeaway is that for anyone who is not vitamin A deficient, eating carrots will do nothing. Vitamin A deficiency certainly causes poor night vision because the body cannot produce rhodopsin. But no amount of beta carotene will make normal night vision better, and therefore the article is not fake science at all.
- omginternets 10y ago>I think the takeaway is that for anyone who is not vitamin A deficient, eating carrots will do nothing. I imagine that vitamin-A deficiency must have occurred rather frequently under WWII rationing. Perhaps this was a real concern at the time?
- giardini 10y agoVitamin A deficiency is surprisingly common today. An interesting story about Eduard Schwarz, an early doctor/researcher (plus much about vitamin A) is at: http://www.westonaprice.org/health-topics/abcs-of-nutrition/vitamin-a-saga/ http://www.westonaprice.org/health-topics/abcs-of-nutrition/... An Excerpt: "Eduard Schwarz (1831-1862), a ship’s doctor on an Austrian frigate that was sent around the world on a scientific exploration. Before his departure from Vienna, several physicians had asked Schwartz to test the old folk remedy of boiled ox liver against night blindness. On the voyage, 75 of the 352 men developed the condition. Every evening when dusk came, they lost their vision and had to be led about like the blind. Schwartz fed them ox or pork liver and found that the night vision in all of the afflicted was restored." More about Schwarz: http://www.sciencedirect.com/science/article/pii/S0899900797002037 http://www.sciencedirect.com/science/article/pii/S0899900797... Should you want to test yourself, a teaspoon of cod liver oil should do the trick. Animal-based versions of vitamin A seem to be more efficacious than their vegetable analogs. Meanwhile eat your liver(mmmm!), fish, carrots and blueberries.
- teilo 10y agoI have experienced reduced night vision to a degree while driving at night. I now take cod liver oil capsules (for other reasons), and have no trouble at all now.
- empath75 10y agoA personal anecdote based on subjective evaluation of your night vision isn't science.
