What makes glasses work

That means that, during the day while looking at the computer, I would want my prescription as well as blue light blocking lenses. Because I have an astigmatism, I generally do not rely on over-the-counter reading glasses, which do not address the issue. It turns out companies everywhere are jumping on the blue light bandwagon. These are the companies I looked at when deciding whether to order prescription blue light filtering glasses:.

There are seemingly endless options when it comes to buying non-prescription or reader glasses with blue light blocking or filtering features.

Almost all of the companies who sell readers provide an option for blue light filters. On Amazon, there is an entire universe of computer glasses with blue light features. You can really fall down a rabbit hole looking at brands and reviews.

Here are a couple of options for finding cheap blue light computer glasses on Amazon:. In the end, I decided to go with blue light blocking glasses with a prescription built in, rather than blue light blocking computer glasses or cheaters. Much of my eye strain digital or otherwise is caused by my astigmatism. I wanted to neutralize that factor in attempting to evaluate the effectiveness of blue light blockers. I chose to go with Liingo Eyewear, as I wanted to test out their home try-on program and get a better look at their frames that I had been stalking for months.

I have worn them at the computer during the day, and then again at night while watching TV and reading before bed. On purpose, I broke my rule to not glance at my phone 30 minutes before bedtime. I know that looking at my phone, computer or ipad right before bed makes me loose my sleepiness. It made a difference. I have found myself having less trouble falling asleep after looking at my phone with the glasses on.

But do gaming glasses that incorporate blue light filtering improve your game, as most manufacturers claim? While there have been a lot of studies on blue light and the impact that it has on our eyes and bodies, there have been no studies on the improved performance that manufacturers of gaming glasses promise.

The consensus is that gaming glasses protect your eyes but might not save your stats. That doesn't mean that gaming glasses don't work, it just means that we don't have hard numbers backing up the claim. But, the theory makes sense.

Oakley designs lenses for other conditions or pursuits, like snow and cycling.
