Blue filter lenses block out the stimulating LED light that digital devices emit so if you like to browse your phone or read your tablet before bed or if you work late hours at the computer our blue filtering computer readers will decrease the stimulating effects of those devices. They are clear coated to eliminate glare with just the right amount of transmittance to block blue light stimulation and harmful UV and still maintain color resolution.
How we use digital devices and for how long we use them is what causes eyestrain. Looking at any digital device for a long period of time or for that matter reading a book for any length of time puts a strain on the eyes muscles because they must contract to keep your vision in focus. Doing that day after day creates tense eye muscles - that’s why even people in their 20’s and 30’s who normally wouldn’t wear reading glasses are finding that a slight correction (+.50 - +1.00) makes a big difference in reducing their eyestrain. The older you get the harder it is for your eye muscles to maintain that contracted state so the lens power usually goes up. Lens quality will also determine the ease at which you read. An optically precise, clear lens sends an unobstructed sharp image to the visual part of your brain- so you can read clearly and comfortably for long periods of time.
If eyestrain has created a discomfort level that has affected your quality of life, then our computer readers will help. If you are using your digital devices before bedtime, then our blue filtering readers will help reduce its sleep-disturbing effects.
