BLUE LIGHT CONFUSION
WHERE DOES BLUE LIGHT COME FROM?
The primary sources of harmful indoor blue light are the TVs, smart phones, tablets and computers we use every day.
HARMFUL EFFECTS OF EXPOSURE
There are three concerning threats from blue light:
Damage to Vision
Loss of Sleep
HOW MUCH BLUE LIGHT SHOULD YOU FILTER?
You should filter only as much as you need to reduce the threat. First look at how much time you spend in front of your devices at night and use the MPF rating that is most appropriate.
Why use computer glasses with lenses that contain melanin?
Melanin is nature's sunscreen and is a very effective way of protecting our skin and eyes from damaging light. There is no question in the scientific community as to melanin's ability to do its job shielding our DNA from damage that high energy visible (HEV) light can cause. Melanin is uniquely qualified for use in lenses because it not only filters out the harmful blue light at the lower end of the light spectrum but it allows the right light into our eyes that we need to effectively distinguish images and reduce glare. Tests show that melanin lenses are superior to other lenses due to their ability to filter colors in proportion to their damage - thereby reducing the risks of macular degeneration and cataracts – while still providing excellent color perception.
Researchers at Photoprotective Technologies have taken a scientific approach to solving the problem with blue light. After clearly identifying the problem and developing a patented system of measuring the effects of blue light on the body's production of hormones that promote sleep, time came for testing ways to solve the problem. Like most great discoveries, the answer was found in nature. Melanin has been used for millions of years to protect animals from the harmful light from the sun. Melanin in our skin, and eyes, is what helps prevent the damage to our DNA from sunlight which would cause malignant melanoma (skin cancer). Photoprotective Technologies developed a way to infuse synthesized melanin into eyeglass lenses and use the body's own pigment to extend the protection that already exists in our eyes. It was also discovered that by using melanin in the lenses instead of other blue light blocking technology, melanin eyeglass wearers reported less color distortion and could perceive more distinct colors.
