About Photoprotective Technologies, Inc.
Photoprotective Technologies (PPT) has been developing a technology of photoprotection (protection from the damaging effects of sunlight and fluorescent lighting) using melanin as a paradigm. Melanin has been evolved by nature to protect humans and animals from sunlight damage; so it's a reasonable idea to use melanin as a guide to understanding the character of both damage from light and protection against such damage.
In fact, the melanin paradigm has guided PPT to invent other new technologies like OLP (ocular lens pigment) and even air filters that use melanin instead of carbon black to trap and sequester airborne molecules that are toxic to humans.
