I have been consistent for the past decade when these first came out that it made no sense to block a specific color. We are finally getting some studies that back this up.
I know many people with their $10.00 "blue light" lenses feel like it helps but the research does not show this to be true. This is all placebo effect. Any claim that blue light from screens is harmful is completely false. When you go outside you get 100,000 times the amount of blue light from the sun that you would ever get from a screen.
Also, if you can see the color blue through your "blue light" glasses - what exactly are they even blocking?
If you want to reduce computer eyestrain, get glasses that properly correct your prescription if you need them. Every 20 minutes take a 20 second break from looking at your screen and focus on something at a distance. Make sure you are addressing anything that could be causing dry eye issues, such as fans or vents blowing on you. Invest in a quality computer monitor. We do have studies that show less strain and more productivity when the clarity of the monitor is better. Address overhead lighting issues. Fluorescent lights that flicker or lights that glare off your screen will contribute to strain.
Ultimately the human body is not designed to sit in front of a screen for 8-10 hours a day. Get up and move around if you can, this will lower blood sugar and insulin levels, especially when done after meals.
That is all for now, thanks for reading!
