Do Blue-light Glasses Really Work?

Over the last few years, the consumption of technology has increased. As an online tutor,  I utilize technology daily. I use technology to teach, plan, grade, communicate, and find online resources. During this usage, I consume blue-light. I had blurry vision, a headache, dry and irritated eyes. I did some research and found that I was absorbing blue-light, which could be the cause of my blurry vision, headache, and dry, irritated eyes. Here’s what I found.

What is Blue-light?

Blue-light is the light displayed by computers, tablets, and phones. This light is often associated with day time. There are many types of light, but blue-light is the only type of light that passes straight to the retina from the cornea. Too much blue-light can damage cells and disrupts sleep patterns. Because of the association between blue-light and daytime, our body cycles get interrupted. Research shows that blue-light can contribute to eye strain and increase the chance of macular degeneration. It scared me, so I looked into ways to solve my problem. As an online tutor, I have to use technology, so I researched ways to help with my eye strain.

Ways to Reduce Eye Strain from blue-light

As I researched, I found a few ways to reduce eye strain from blue-light consumption. I couldn’t refrain from using technology, but this wasn’t an option, so I looked at other ways.

20-20-20 Rule

One method I found was to use the 20-20-20 rule. This rule says that after 20 minutes of computer or technology used to look away at something 20 feet away for 20 seconds. I tried this for a while, and it didn’t quite work. I was distracted, trying to remember to look elsewhere.

Use eye drops

I tried using eye drops whenever I felt my eyes get tired or strain, but I found this unproductive. I was going through a lot of eye drops.

Sit Away From Your Screen

I read somewhere that I should set at least an arm’s length away from my screen, and I tried it. It was fine until I went to do a video lesson, and I felt too far away to control my computer.

Using Blue-Light Blocking Glasses

Finally, I decided to try some blue-light blocking glasses. I had read about them and seen several pairs on Amazon and thought it wouldn’t hurt to try. I researched the blue-light glasses and wasn’t hopeful. There isn’t much research supporting the use of blue-light glasses. The FDA doesn’t regulate eyewear, and most eye doctors think you should not use digital devices as much. After using the blue-light blocking glasses for a week, I saw considerable improvement. I no longer had headaches. My eyes didn’t hurt and didn’t feel strained.

Do Blue-light Blocking Glasses Work?

I tested blue-light blocking glasses for one working week and in my personal experience, blue-light blocking glasses worked for me. I had better sleep, less headache and less dry eyes. Although there is not much research and are scientifically not proven to work, they helped me through the week. The blue-light blocking glasses took a while to get used to, but I feel better at the end of the day.
