Computer reading glasses, also called anti-blue ray reading glasses, are reading glasses made for screen work. The lens filters a portion of the blue light that screens give off, and many customers like the slightly warmer tint it adds.
The main difference from a book-reading pair is distance. A screen usually sits 50 to 70 cm (20 to 28 inches) from your eyes, further away than a book, so many people find a slightly lower strength more comfortable at the computer. For example, if you read with +2.50, try +2.00 for the screen. If you are unsure, check with your optician.
For comfortable screen time, eye-care professionals give simple advice: keep the screen at arm's length and slightly below eye level, and follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds.
Frequently asked questions
Do anti blue light glasses work?
Research so far has not shown that blue light filtering lenses reduce eye strain from screens. Many people like the warmer tint. Using the right strength for screen distance and taking regular breaks helps most.
Which strength is best for computer work?
Most people choose about 0.50 less than their reading strength, because a screen sits further away than a book.
Can I wear them for reading as well?
Yes. They are reading glasses with a blue light filtering lens, so they work for reading too.
How can I make screen time more comfortable?
Keep the screen at arm's length and slightly below eye level, and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
