Blue Light Blocking Glasses - Computer Glasses Anti Eye Strain Headache

The media could not be loaded.  I was pretty suspicious but figured I'd give these blue blocking glasses a shot (I have apps to dim my electronics , but glasses could block blue from my house bulbs which don't all have dimmer/color control). Superficially, they look fine. They're too wide, but they'll stay on so whatever. Now on to what they're actually for:For reference, melanopsin (blue sensitive pigment in those special eyeball cells you read about) is tuned maximally to about 480 nanometers - if you look at a picture of the visible spectrum, this is about where cyan sits (probably not surprising, looks a lot like daylight bluesky). There's a spread though, from roughly approx 400 to 550nm, in a symmetrical distribution curve, so at 420nm for example it would take a lot more photons than at 480nm to get the same firing response from eyeball to brain. So this is the target range to block if you're goal for blue blocking is nighttime/sleep/melantonin related.Review Evidence:Photo1: Held up to my laptop screen on 100% brightness, you can see there is actually the faintest of yellow tint to these lenses - hence I my title is "mostly" ineffective. They provide jack squat evidence, but I'll assume they do some minimal filtering there. Not nothing, but probably close.Photo2: If you look at an image online that is meant to test blueblocking (the lower strip has blue removed by photoshop, so if the glasses blocked the blue from the top strip getting to my eyes, the strips would look the same). No.Also, I looked through a handheld spectroscope at my laptop on a section of white screen at 100%, moving the glasses to cover/uncover the spectroscope light entry slit. The laptop blue LED produces a bar at about 450nm, and these glasses essentially don't change that bar's intensity at all. (ZE GOGGLES, THEY DO NOTHING!!)Video: This is the part that is flat out MISLEADING, and I would be unsurprised if this is how many more of these "test cards" work - they change color strongly in response to *UV wavelengths*. My laptop screen at 100% no matter the color does not change it. My UV lamp for gel nail polish sure does though!! Nail lamps are in the 300s to 405nm range. Other tested items not in video: Lamps in my house with very strong blue spectrum, from cyan to violet, do not produce color change. Blue LED on my security camera does not. My footlong MagLite's incandescent bulb left directly on the paper for 5-10s changes it *faintly* (incandescent bulbs' spectrum output continues weakly into UV).CONCLUSION:1. As of 6/6/20, this product description claims "100% effectively block harmful blue light coming from phones, computer monitors, gaming, and other devices," and "...full blue light protection...", and "...filters out almost all of blue light..." False. These glasses do very little to reduce blue light. I'm not even shocked at that, the claims are ridiculous.2. The test card marketing, however, is misleading trash, due to the fact that they provide a card to "prove" their product that is in fact tuned most strongly to light that your electronics and house bulbs don't produce. If the test card responds to the very tail-end of the visible spectrum in the blueviolet range at all, it's only at power that my house lights and electronics screens cannot produce.Oh and if you have an problem, an insert in the package says "We do not encourage you to leave message of the issue under 'review' or 'feedback'" because it will be "difficult for us to get your contact info to reach out and solve the problem.... Sincerely, Marketing." ...Mmmmm hmmmm.

Like most of the world, once COVID hit, I found myself sitting in front a computer for hours upon hours, so I wanted to look into some blue light blocking glasses. These were actually recommended by a blogger I follow, so I thought I'd give them a try. That was a mistake for three main reasons.First, there were no directions about what to do with the test strip and light so I had to go online and Google the correct way to use them. What I read online says that if the glasses are working properly, the test would yield a blue color on the test strip. These yield a violet color, which apparently means they are doing nothing for blocking blue light. I also read that the shade of blue on a computer screen should be altered or not present. I see absolutely no difference when I have the glasses on.Second, these glasses are HUGE on my face and I felt strange wearing them during virtual meetings (which is a lot of my day) because they look so funny on me.Third, and most important, the glasses caused headaches rather than alleviating them and made it hard to focus. The best way I can describe it is when you put on glasses that are too strong of a prescription and you almost feel cross eyed. I tried on multiple occasions to wear these glasses, trying to give them another chance, but I couldn't keep them on for longer than 5 minutes because of the strain they put on my eyes. Not worth it.

I was really excited about getting these glasses, I think they are absolutely adorable and the whole reason I bought them are for the blue light blocking. BUT I dont even know if they are true blue light blocking glasses because I can not tell by wearing them and I was never given a blue light or a tester card in order to show that they actually work. Thinking about returning them for a refund because I need real blue light blocking glasses.Update: I returned them, I was very unhappy with the missing items. There was no way for me to test if they actually worked. There are many more blue light blocking glasses on amazon

I noticed I have started getting these mild annoying headaches and my eyes just feeling tired.I have a blue light blocker on my phone but it makes everything very yellow.Never thought about the blue light really affecting my eyes until I read an article.Ordered these on a whim, the price is super low, the don’t look hideous and they work!!!I have an iPad Pro and a Samsung Note 20, been using versions of these 2 devices for years, both of which I am on often shopping, reading, etc., anxious to see if these help, they can’t hurt and for less than $10?!? Can’t even get decent sunglasses for that.

These glasses were carefully packaged and arrived in excellent condition. They are well made and attractive. The blue light coating is ever so slightly amber-ish (from my perspective) but in no way interferes with normal color perception. That slight color shift seems to reduce some of the brightness emitted by electronics, including my TV. Perhaps I squint more than I realize when working at my computer but I noticed a slight easing of tension whenever I wore these blue light glasses.The only reason I gave this pair of glasses is that they were just a bit too heavy for MY comfort. I wouldn't say that they are heavy bit they are just heavier for comfortable wearing over long periods of time.If they came in a lightweight wire-framed style, I'd probably buy those from this vendor.
