Not all blue light is bad - some exposure is good for our health.
Sunlight is the main source of blue light but there are also man-made sources. Fluorescent and LED lighting, flat-screen televisions, computers, smartphones and other digital devices all emit significant amounts of blue light. The amount of blue light from these devices is small compared to what comes from the sun. But the amount of time that people spend, with a these devices at close range, raises concerns about possible long-term effects of blue light over-exposure on eye health.
We are mindful of potential long term health effects of prolonged exposure to blue light, and the short term disruptive effects blue light may have on our daily circadian rhythms. Blue light exposure is implicated in eye strain symptoms, dry eyes and can interfere with sleep patterns. We experience comfort and relief when it is filtered out. This is an easy step if you are already wearing glasses, but what if you don’t need personalized prescription lenses?
