Digital Eye Strain
Most of us spend the majority of our waking hours staring at computers, and video display devices. Digital eyestrain is a new term used to describe the conditions resulting from the use of today’s electronic gadgets.
Digital eyestrain is a medical issue with serious symptoms that can affect learning and work productivity. Symptoms of digital eyestrain include blurry vision, difficulty to focus, dry eyes, headaches, neck and back pain.
Blue Light and Age Related Macular Degeneration
There’s growing medical evidence that blue light exposure may cause permanent eye damage; contribute to the destruction of the cells in the center of the retina; and play a role in causing age-related macular degeneration, which can lead to vision loss.
Melanin is the substance in the skin, hair, and eyes that absorbs harmful UV and blue light rays. It’s the body’s natural sunscreen protection. Higher amounts of melanin afford greater protection, but as we age we lose melanin, so that by age 65 half of the protection is gone making us more susceptible to eye disease such as macular degeneration.
The retina is a very thin, multi-layered tissue covering the inner eyeball. The retina can be harmed by high-energy visible radiation of blue/violet light that penetrates the macular pigment found in the eye. A low macular pigment density may represent a risk factor for age-related macular degeneration by permitting greater blue light damage to the retina.
A Harvard medical study states that “High Energy Visible (HEV) blue light has been identified for years as the most dangerous light for the retina. After chronic exposure, one can expect to see long range growth in the number of macular degenerations, glaucomas, and retinal degenerative diseases”. And a paper published by the American Macular Degeneration Foundation (AMDF) reports that “the blue rays of the spectrum seem to accelerate age-related macular degeneration (AMD) more than any other rays in the spectrum”.
BLUVISOR Lenses absorbs the bluelight and diffuse the energy within, making the ideal lens for computer use.
