BLUE LIGHT & THE HEALTH OF YOUR EYES

You may have heard that fluorescent lighting can be bad for your eyes, but did you know why? In recent years, studies have shown that Blue-Violet light can be damaging to the retina, and therefore has the potential to cause Macular Degeneration (AMD). AMD is a disease of the eye that causes central vision loss.

So, what does this have to do with fluorescent lighting? Higher amounts of blue light are emitted with the use of fluorescent lights, but that’s not the only source. High amounts of blue light are also emitted through the use of LEDs which are found in electronic devices including computer monitors, TVs, and personal devices like tablets and smart phones.

Blue light also affects our circadian rhythm. Melatonin is present at low levels during the day, and increases in the evening to allow us to fall asleep. Blue light suppresses our melatonin output and that, in turn, resets or delays our circadian rhythm, keeping us from falling asleep.

So, what can we do? Lens coatings such as SeeCoat Blue or TrueBlue anti-fatigue glasses block out a large portion of the harmful blue light. If you spend large amounts of time in fluorescent lighting or using computer, tablets, ask your optometrist about these protective coatings.
