Blue Light Filtering
Technology
Blue light is present outdoors as a component of natural light.
Blurriness and Reduced Contrast
Blue light tends to scatter easily causing blurriness and decreases in color contrast. Blue Light Filtering AR selectively filters out high energy harmful blue light while letting beneficial turquoise blue light pass through.
Digital devices and modern lights are a few of many light sources that emit blue light.
BLUE LIGHT – The Good and The Bad
Visible light is both harmful and beneficial to vision and health. “Blue Light”, also known as High Energy Visible (HEV) light, is the shortest and highest energy light ranging from 380nm to 500nm within the visible spectrum. Blue light in 470nm to 500nm range is generally considered beneficial and provides natural reflexes protecting eyes against light overexposure. It also provides for the right functioning of the circadian rhythm (sleep/wake cycle), memory and cognitive performance. However, blue light in 380nm to 470nm range, which is violet-blue in color, is generally considered harmful and can cause accumulated potential damage to the retinal cells. It can also reduce contrast and decrease sharpness and clarity of vision.
Blue Light Filtering AR provides increased protection from blue light health hazards in addition to providing all of the benefits of a premium anti-reflective coating.
Benefits of the Blue Light Filtering AR
- Reduces accumulated potential damage to the eyes from harmful high energy blue light
- Allows good blue light to pass through the lens for increased visual acuity and clarity
- Provides protection against back-surface UV reflections
- Super-oleophobic, an-static, scratch resistant and repels dust, smudges and water
