Blue light is part of sunlight. We see it when a rainbow or a glass prism separates out the colors. Medical scientists tell us that the blue part of sunlight can increase your risks for macular degeneration – the leading cause of blindness for people over the age of 55. And blue light emissions from cell phones, tablet PC’s and TV screens at night time can make you lose sleep due to suppression of melatonin by blue light.
And loss of melatonin and sleep will increase your risk of cancer, Alzheimer’s, diabetes and obesity. It will also increase your appetite at night time.
One answer to this problem is effective filtration of the blue light. MPF™ 6 Eyewear with Melanin and OLP offers a natural solution to blue light with minimal disruption of color perception.
Photoprotective Technologies has been working on this problem for years. The solution is using a natural filter– an organic one. The body has a natural defense to harmful light called melanin. It’s in your eyes, hair, and skin and protects the body from damage. Using the same melanin, PPT has developed lenses that contain the natural pigment and can be a natural filter to harmful blue light.
How much blue light should computer glasses filter? If you filter too little blue light, your body makes less melatonin; if you filter too much you don’t see the colors well. In 2014, Photoprotective Technologies filed patent applications for a way to rate computer glasses for their ability to filter the blue light wavelengths that reduce the production of melatonin. For example, sleep researchers have found that a 22 % decrease of melatonin production at night time can occur after two hours of computer use. This means that the MPF™ 6 computer glasses will extend this exposure time to 12 hours.
