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. Because of the association between blue light and daytime, our body cycles can get interrupted. 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.
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 blocking glasses and wasn’t hopeful. There isn’t much research supporting the use of blue light glasses.
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 work 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.
