Do Blue Light Glasses Work? An Honest Answer
Blue light glasses are popular, and many people find them more comfortable. Here is what they do, and what the evidence says.
What they do
A blue light filter reflects or absorbs part of the blue light from screens and LED lighting. Many users report less glare and a more relaxed feeling.
What the evidence says
Studies have not shown that screen blue light damages the eyes, and the main cause of digital eye strain is long focusing time and less blinking. Breaks and an up-to-date prescription matter most.
When they are worth it
If you spend many hours at a screen and like the more comfortable feel, it is a low-cost addition: Blue Light Comfort is +$18 at Verly. Pair it with anti-reflective for less glare.
Frequently asked questions
Can I get blue light glasses without a prescription?
Yes, many people use non-prescription screen glasses.
Do they help me sleep?
Reducing evening blue light may help some people, but turning screens off before bed helps the most.
