“90 % of the light that enters the eye is filtered by the melanin and OLP. These pigments filter the wavelengths of light in proportion to their damage. “

 It is reasonable to use synthetic versions of these pigment in sunglass lenses to protect the eye of children.

Blue Light in Adults

Adult’s eye has OLP which filters the blue light – less damaging blue light reaches the retina.
        Problem: Adult eye has less melanin, therefore more glare.

Blue Light in Children

Child’s eye has more melanin, therefore minimal glare.
        Problem: No OLP is present, allowing all harmful blue light to reach the retina. This disrupts the child’s circadian rhythm and increases the risk of macular degeneration.

The Solution?

Glare Reduction and Blue Light reduction with OLP in Melas

The Logic of Melanin/OLP Filtration

PPT has been using melanin as a model for developing a technology for sunglasses and computer glasses that protect and even repair vision. This approach has had ground-breaking success!

Melas™ sunglasses provide vision protection and vision enhancement, unlike any other material – the way nature intended.

  • Filtration of the wavelengths of light in proportion to their damage (transmission is progressively higher as the wavelengths increase toward the safer low energy light.
  • 100% filtration of UVA, UVB and UVC.
  • Very low transmission of damaging blue light(from 430nm – 450nm);
  • Moderate transmission of the good blue light (460nm – 500nm) – the blue light that wakes you up and sets your circadian rhythm;
  • High transmission where the eye is the most sensitive to light (550nm);
  • And 100% transmission where repair is greatest (670nm – 1000nm);
