Bluelight blockers test

[s-kur]

I came across the test that reflects how your anti-blue glasses really works _https://spectra479.com/test-strip/

According to this test my Xiaomi glasses doesn't work at all unlike Windows 10 "Night mode" function which really makes both strips identical.

My Uvex S1933X glasses passed the test.

My glasses didn't pass the test, which I bought from zenni.com and are supposed to block blue light. That's annoying.

That's really useful, thank you for posting this s-kur! My glasses passed the test and I bought a relatively cheap product on Amazon.

Despite your glasses failing the test, have you noticed any difference in the quality of your sleep when using them Beau? Or any other benefits that you were hoping for when when you decided to get them?

Not really, although I wasn't having any issues sleeping before getting them. I was interested in blocking blue light overall because it's everywhere but haven't noticed any benefits, although I might know why now! My sleep hasn't been any different.

I think this is because the ones from Zenni and Bluetech are designed for daytime use and overall moderate protection, not circadian rhythm optimisation. They do block specific frequencies of blue, but not a lot. For sleep, they are not sufficient.

These ones are the most cost effective method: https://www.amazon.com/Uvex-Blocking-Computer-Glasses-SCT-Orange/dp/B000USRG90/ref=sr_1_2?ie=UTF8&qid=1506630639&sr=8-2&keywords=uvex+skyper

For a total of $9, they block out pretty much all of the blue and fit tightly around the face.

For daytime use, there are options that can block out more blue light. I use lenses called "BPI tints", specifically 450nm in the daytime. These are yellow in colour, and block out all light below 450nm. I also have a pair of 500nm and 550nm lenses and where them when it is appropriate. I do this mainly to protect my eye, rather than protect my sleep. For sleep quality, the goggle-type glasses (and similar ones) I linked to above are the best option and the only type which are effective.

That all makes sense, but I can't go to work wearing yellow tinted glasses. I would be told to go home and put on a "normal" pair of glasses. As for the goggle type glasses from Amazon, I wear them the last hour or two before bed almost every night. But since they aren't prescription, I only wear them when I'm in bed reading.

Hey Keyhole, I have the same night time glasses you linked above and I agree they're pretty awesome. As for the "BPI tints", I can't seem to be able to find them on Amazon, did you buy your from an optician?

Yeah you go through optician to get them.

I used this company for the lenses : http://www.norville.co.uk/acatalog/catalogues/PLS%20Tints%20816v4.pdf

Thats a shame. I work in a school, and I wear them to work. People barely comment, only sometimes to say the look cool. When they ask why I wear them, I say 'because my optician said it would stop me from getting headaches', and no more is said on the subect. But that all depends on your workplace environment I guess. Either way, the zenni ones are better than just any old standard ones :)

My glasses also didn't pass the test. I have then about 10 years. Although the lenses have some kind of blue-green reflection when looked under specific angle they dont pass the test. If you look straight at the lenses they look transparent just like a regular glass. I think that they have anti-glare lenses but I am not sure.

But they are helping me. With them, I can seat a lot of hours in front of a computer and feel pretty fine. Without them in an hour my eyes are tired and usually, after that, i get a headache.

Hi, all,
One thing I did, hoping to reduce my own exposure to blue light, was to go into my computer control panel and change the desktop on my computer from the Microsoft blue to a dark red background behind an image with minimal blue.

Does anyone actually know whether that does enough good to warrant the trouble?

It probably helps some, but better to install f.lux or iris software to reduce computer blue light.

Software solutions like Windows 10 Night Mode can't be considered reliable using this test. To assess the efficiency of software "blocking" one has to test it with and without good blue-blocking glasses like Uvex S1933X.

Thanks for this 3D Student. I've installed f.lux and the colours on my screen look quite similar to what they look like through my orange glasses. However, just like with the orange glasses I do find it a bit uncomfortable to read on screen. It seems to be quite tiring for my eyes :/ Do you have that software installed and do you have it 'on' at all times? Do you find it comfortable to read?

Thanks for the test s-kur! Mine passed. I am wearing these

because they fit over prescription glasses. Not the most stylish, but they are getting the job done.
