He said while blue light doesn’t damage our eyes, some studies show looking at your phone or the TV before bed can make it harder to fall asleep. While Hawkins said there isn’t enough good evidence to show that blue light lenses are helpful, he said some of his patients do report feeling fewer headaches.
I get to sit at my desk all day, write about technology, and play with the latest gadgets, all while making a living. On a busy day, I can be sitting at my computer for eight to 10 hours at a time with minimal breaks in between sessions.
Regardless of how busy I am, writing articles while staring at a computer screen all day can lead to negative health effects. For instance, some may be exhausted at the end of the day or their back might get sore from sitting too long.
Not only do your eyes feel like absolute trash, you can get a headache at the end of the day and have problems falling asleep. I need to be able to work however long I need to during the day, take breaks when I feel like it, and go to sleep with ease.
All the side effects I listed are symptoms of what’s called Computer Vision Syndrome, or CVS. Essentially, it’s what happens to your eyes when you stare at a computer screen for too long, and it’s caused by the blue light being emitted by the display itself.
But when you’re exposed to levels of blue light your body isn’t designed to handle, it can lead to drops in your overall health and well-being. I’ve been skeptical of these things for years since I never actually bought the whole message of “Oh, they’re soon good for your eyes!” But then, I was contacted by the kind folks at Pixel Eyewear, a company who specializes in computer glasses without the harsh amber tones of typical blue light filters.
They offered me a pair to try out, so I sent them my prescription, selected a style, and decided to wear them for a full month before sharing my thoughts. Folks, I’m happy to report that not only do these things work, but they’ve also changed my life.
A common concern many people may have when it comes to buying something called “computer glasses is the fear of looking weird. They let you choose from a variety of fashionable frames that don’t look nerdy or off-putting, while their lenses aren’t yellow or unnecessarily colored.
I’ve seen a lot of manufacturers basically tint lenses yellow and call them glasses that are perfect for using with your computer.” With Pixel, on the other hand, you get lenses that are manufactured using a special process that filters out 50 percent of the blue light emitting from your device and up to 95 percent at the highest wavelengths. The first time you put them on, you’ll immediately notice a sort of greenish tint that may seem off-putting for a few minutes.
As I said before, I’m staring at a screen for a vast majority of my day, and any chance I get to take a break to give my eyes some rest is always appreciated. Of course, staring at a screen for so long during the day will still make your eyes tired, even if you filter out all the blue light emitting from the device in question.
Speaking of hitting the hay, I’ve also noticed it’s become easier for me to go to sleep at night. Considering I’m taking in less blue light and receiving a natural, healthy amount while I’m outdoors, my brain can better tell when it’s night and time to get some rest.
And yes, this isn’t a very scientific review, but from a standpoint of an average person who wants to experience less eye strain, Pixel’s blue light -filtering glasses are perfect. Computer glasses designed to limit blue light exposure has seen popular demand in the last five years.
Likewise, the wavelength of blue light is also found to cause a perception or a feeling of fatigue on the eyes. In clinical studies, the long-term effects of blue light exposure lead to damages inside the eye, specifically in the retina.
It is found that through the duration of our lives when our eyes are exposed to blue light, the damage compounds and leads to a condition called age-related macular degeneration (AMD). Age-related macular degeneration (AMD) causes irreversible damage to the eye's retinas, which is responsible for our perception of light and our ability to see.
In longer-term studies, it has also shown that wearing bluelightglasses can also delay the onset of age-related macular degeneration and other blue light related retina problems. The results of studies surrounding digital eye strain have continually shown promising results, and some ophthalmologists and optometrists recommend having a blue light filter on your prescription glasses when headache or the strained feeling occurs.
And for sleep quality, studies also show that the bluelightglasseswork well enough to still allow the production and excretion of melatonin despite being exposed to blue light. There isn't any harm of wearing one, and the potential benefits of using spectacles with blue light filters give the general population nothing to lose.

The truth is, there's little in the way of conclusive evidence (beyond the anecdotal) to suggest blue light specifically contributes to eye strain, and if your eyes are feeling bleary from staring at your screen for too long, you might be better off adopting the 20-20-20 rule, an easy process that involves looking at a point 20 feet away from your screen for 20 seconds every 20 minutes. Experts do, however, recommend cutting back on blue light exposure at least a couple of hours before bed to avoid disrupting your regular sleep cycle.
