Blue light protection glasses are a necessary evil these days. Today, we will review why they are important and also show you the best blue light glasses on the market.
So let’s get started and teach you why blue light filtering glasses are important.
Protect Yourself From Blue Light – The Increasingly Pervasive Evil
Blue light is everywhere. It’s coming from the screen your looking at right now – your phone, tablet, or computer screen. It comes from your TV. It comes from your modern-looking cool-white LED light bulbs. It’s everywhere.
Unfortunately, the eye is not good at blocking blue light. The eye is good at blocking other types of light such as UV rays. Only 1% of UV rays reach the retina (the back of the eye) (Note it is still important to wear sunglasses that block 100% of UV rays to protect eye from damage). However, the eye is horrible at blocking blue light. In fact, virtually all blue light reaches the retina.

The Negative Effects of Blue Light
Blue Light Blocks Melatonin
Possibly one of the worst side effects of excess blue light exposure is that it disrupts the body’s natural sleep-wake cycle.
Blue light disrupts sleep because it blocks the secretion of melatonin. Melatonin is the hormone in the body that tells your body that it is nighttime. Even small low intensity blue lights can prevent the release of melatonin.
For many people, blue light late at night will cause difficulties with falling asleep. Others can fall asleep just fine, but it is still impacting the quality of their sleep.
To solve this issue, you can either take a melatonin supplement or you can wear glasses that block blue light. While I highly recommend considering melatonin, I understand when someone tells me they would rather not be taking another pill. Blue light filtering glasses work perfectly in these situations.
Blue light protection glasses allow your body release melatonin the natural way. It is still wise to turn down the brightness and minimize blue light from your cellphone and computer screens.
Blue Light May Increase Risk of Macular Degeneration
Blue light penetrates all the way to the retina. The retina is the inner lining of the back of the eye. It is the retina that sends the visual information to the nerve that thereby sends it to the brain.
Laboratory studies have shown that too much blue light can damage cells in the retina. This causes changes that resemble those of macular degeneration.
More research needs to be done to determine how much blue light is too much for the retina. Regardless, many eye care professionals are worried about the amount of blue light exposure the average person receives.
Does Blue Light Cause Eye Strain?
The jury is still out on whether blue light causes eye strain. Frequently, when people are staring at computer screens they blink less often. This eventually results in digital eye strain. It causes symptoms such as dry eyes.
There is no scientific evidence to suggest that blue light, itself, actually causes eye strain.
Benefits of Blue Light
Not all blue light is bad. It is established that blue light exposure helps improve alertness, helps memory, and elevates mood.
In fact, one of the may stays of treatment for seasons affective disorder is a light box. Light boxes these days primarily use blue lights. The current light/dark receptor is tuned to sense primarily blue light, which is why it plays such a big role in mood. This makes sense, as the lack of blue light is what allows for the release of melatonin (as stated earlier).
Blue Light Filtering Prescription Glasses
Certain prescription glasses also come with blue light filtering options these days. These glasses do not have a yellow tint because they filter out blue lights that are at the higher end of the spectrum.
Warby Parker offers this blue light filtering option on some of their glasses.
Be careful though, as I said earlier, blue light can also be a good thing, particularly in the morning to help wake you up. It can also be helpful to prevent depression in people with seasonal affective disorder. I primarily recommend minimizing blue light exposure later in the afternoon as this is when it impacts the sleep wake cycle.
