Melanin absorbs light smoothly over a broad spectral range. It absorbs the higher energy light more strongly than the lower energy light. So it absorbs UV more than blue, and the blue more than green. This makes melanin superior for photoprotection because of it’s ability to filter light in proportion to its damage. This happens naturally with melanin – through the wisdom of nature.
In the eye, melanin reduces the risks of macular degeneration. In optical lenses, melanin reduces the risks of cataracts and macular degeneration without losing the perception of color. Melanin lenses are able to reduce glare, even without polarization, while offering exceptional protection and comfort for your eyes.
Our melanin technology provides glare reduction and eye protection from sunlight damage that is engineered by Nature. The melanin that we produce provides the filtration in lenses for sunglasses, reading glasses, computer glasses, pilot glasses, night driving glasses, sport sunglasses and other special purpose sun glasses. PPT also grants distribution licenses to market and sell Rx Sun lenses with melanin in the US.
All of our lenses offer protection from UV and HEV (high energy visible) light. They include a scratch protective coating as well as offering true color, glare reduction, and natural protection to the lens and your retina through the use of melanin.
Two pairs of glasses in one! Computer glasses that transition into sunglasses when stepping outside. Our patented Sun and Sleep lenses with melanin offer protection from the sun while enjoying outdoor activities during the day and filter harmful blue light from artificial lighting and electronic devices while indoors. Using these lenses at night combats the suppression of melatonin caused by blue light emitted by artificial lighting allowing for better sleep.
Nearing the clinical trial phase in development, PPT’s latest sun lenses offer vision protection and repair for the first time. These revolutionary sunglasses are coated with nanoparticles which convert harmful wavelengths of sunlight into therapeutic wavelengths of red and near infrared light that has been clinically proven to improve functioning of cells and tissue.
The ultimate protection from blue light while maintaining color perception! These blue light filtering lenses are best used as indoor lenses for long hours of computer use in order to maintain natural sleep patterns and melatonin production.
Utilizing melanin and its natural light filtering properties in sunglasses provides superior protection from UV and HEV light. Available in brown or gray, as well as polarized and non-polarized.
Reduce eye strain and improve comfort. Ideal protection for eyes that require powered lenses while using a computer. With melanin infused reading glasses, add a layer of protection between your eyes and the blue light emitted by computers, tablets and phones.
Near clear prescription lenses offer everyday protection against damaging blue light while still preserving color perception. Our melanin is infused within the lens itself so no need to worry about a coating that will scratch or fade away. Also available in a sun lens.
Enhance contrast and reduce glare. Driving glasses are especially useful during dusk and dawn when a majority of accidents occur. At those hours, other cars, pedestrians ,and obstructions can be concealed in shadows offset by a brightened sky. Melanin driving lenses will not reduce visibility like sunglasses will but offer eye protection from UV and blue light while preserving color perception and allowing for improved contrast.
Did you know that teams in Antarctica use goggles with our melanin to prevent chronic eye irritation associated with glare. Melanin goggles and glacier mountain lenses provide glare reduction in extreme sunlight conditions while allowing for the color perception needed to navigate terrain safely. Made from impact resistant plastic, these lenses are only available through special orders and come with a lifetime guarantee.
