Scientists at Photoprotective Technologies, Inc. have developed the patents and technologies to synthesize and chemically modify melanin so that it can be incorporated into optical quality plastic lenses. The support for most light filters (whether they are lenses of film) is plastic.

Melanin is inherently hydrophilic, while plastics are inherently hydrophobic.  So, it’s a real clash when the two materials meet.  The tendency for melanin to clump up and aggregate is always there – even if it is not mixed with plastics.  For lens applications, this situation is more than challenging and PPT has spent decades addressing this challenge
