What is Blue Light
Did you ever wonder why your eyes feel tired, dry or irritated after sitting at a computer for a long time? Is there any truth to the theory that staring at a computer tablet or cell phone for a length of time before going to bed can be the cause of sleeplessness? Can computer glasses really make a difference?
Everyone should rely on an eye doctor to recommend computer eyeglasses and lenses that can block and protect eyes from damaging blue light.
The display screens of computers, tablets, flat screen televisions and smart phones emit significant amounts of blue light. Blue light occurs naturally in nature and sunlight is the main source. While we do need a certain amount of blue light for good health, too much of it concentrated on our eyes for hours at a time can cause problems such as significant eye strain.
This article from All About Vision offers an easy to understand explanation of blue light emitted by some computer equipment and its affects on eyesight.
Blue Light And Eye Strain
So much of what we do at work and even for pleasure at home involves computers; you can’t get away from it unless you’re not going to watch television, use a tablet, computer or cell phone. I know that won’t work for me! I typically spend eight hours a day at work with a computer, an hour with the television after dinner and at least an hour with my tablet reading news or enjoying social media or other Internet browsing.
While I can’t say I suffer from sleeplessness, my eyes are definitely showing the damage from eyestrain after just a few hours in front of the monitor. They feel dry, irritated and sometimes painful. My eyeglass prescription is up-to-date but my eyes still suffer. That’s what made me explore options for ways to filter out the damaging blue light from my electronic devices with computer glasses.
Computer Glasses Protect Against Blue Light
Just like other options, eyeglass manufacturers offer coatings to filter out harmful blue light for an additional cost over plain lenses. It can be a fairly costly option. Not sure that I wanted to spend a significant amount of money on prescription glasses just for filtering out blue light when using an electronic device, I opted for a pair of clip-on lenses similar to sunglasses that clip over regular glasses.
With free two day delivery using Amazon Prime, the total for a pair of clip on computer glasses from GameKing came to just under $20. They are a good fit for my existing glasses and come with a lens polishing cloth, a mini screw driver, protective eyeglass bag and a very sturdy eyeglass case.
My clip-on lenses came in the mail today and I am anxious to try them out. If I feel they make a significant difference in how my eyes feel throughout the day, I will ask my doctor to recommend eyeglasses and lenses that can block and protect my eyes from damaging blue light because my computer usage is not going to decrease any time soon!
I’ll report back in a few days and let you know how I make out with my clip on computer glasses!
Edit – 30 Day Report
After consistently using clip-on computer glasses while at the computer or tablet for an extended period of time, I definitely feel a difference in my eyes. I spend more than 8 hours a day using a computer for work and another hour browsing the Internet with my tablet at home. I’m not able to judge any immediate benefit to the general condition of my eyesight (only a doctor could do that), but my eyes feel less stressed and tired when I wear the computer glasses. The filtering effect is noticeable as soon as I put the glasses on due to the yellow coloring in the lens. It’s not that everything looks yellow but the decrease in the glare from the monitor is very noticeable and very comfortable.
In summary, my clip-on computer glasses are keepers!
