3 Reasons Why Blue Light Filters & Eyeglass Coatings Are Important, Rochester, New York

Americans spend more than 10 hours a day on electronic devices. The blue light from screens can be dangerous to eye health, and the longer one is exposed to it, the higher the chances of damage. Blue light filters for electronic devices and anti-reflective coatings for eyeglasses can help protect your eyes from the harm caused by extensive screen time. Below are a few reasons why blue light filters and eyeglass coatings are so important.

Why You Should Get a Blue Light Filter & Eyeglass Coatings

1. Blue Light Is Prevalent

People aren't just exposed to blue light on their computer screens. The sun emits high levels of blue light that is essential for maintaining alertness, improving mood, and stabilizing the circadian rhythms needed for healthy sleep. The blue light produced by screens is only a tiny fraction of what is produced by the sun, but given the close proximity of screens to the eyes—typically only a few inches—and the longer exposure times, there is an increased likelihood of eye damage.

2. The Eye Can't Block Out Blue Light

eyeglassesOn a spectrum of severity, blue light is one step below ultraviolet light. But the outer structures of the eye are naturally able to block out UV rays and prevent them from reaching the delicate retina. The eye does not have the same natural capacity to block out blue light, and standard eyeglasses are not able to help the issue.

3. Blue Light Causes Eye Strain

If your job depends on using screens for lengthy periods, you can strain your eyes. You will find it harder to focus on the words and images on the screen, and eye pain and headaches often develop. Using blue light filters on your screens and anti-reflective coatings on your eyeglasses will increase contrast and comfort.
