Blueless lenses are lenses coated with a special film that reduces reflections and glares by allowing more light to pass through. Whereas regular plastic lenses reflect about 8% of available light and high index lenses reflect about 12% or available light, glasses with anti-glare lenses reflect only about 1% of available light, allowing the remaining 99% to pass through, resulting in an increase in contrast and visual clarity.
Blueless lenses are called so because they reduce eye fatigue from sources of artificial blue light such as computer screens, LED televisions, fluorescent lighting, and cell phones. As written about in our article on blue light, blue light has a shorter wavelength and higher energy which requires more energy for your eyes to absorb and send to your brain.
Overexposure to blue light, like sitting in front of a computer screen all day, can cause eye-fatigue as our eyes’ source of melanin, our skin’s natural source of sunscreen becomes depleted, increasing retina damage over time. Bluess lenses help reduce exposure to sources of blue light, reducing eye-fatigue and vision glare.
