| About | Photoprotective Technologies (PPT) has patents and technologies to make melanin and license melanin based light filters such as sunglass, reading and computer lenses. Melanin is the body's own defense against sunlight damage and glare. In sunglass lenses, melanin eliminates UV light and reduces high energy visible light without distorting color. PPT sells CR39 lenses with melanin to sunglass distributors. |
