Materials

PLASTIC

A plastic lens is approximately 50% lighter than a glass lens and can be easily tinted to any color if desired.

TRIVEX

Trivex is a relative newcomer that possesses the UV blocking properties and shatter resistance of polycarbonate while at the same time offering far superior optical quality (i.e., higher Abbe value) and a slightly lower density. Its lower refractive index of 1.532 vs. polycarbonate's 1.586, however, may result in slightly thicker lenses. Along with polycarbonate and the various high-index plastics, Trivex is a lab favorite for use in rimless frames, due to the ease with which it can be drilled as well as its resistance to cracking around the drill holes. One other advantage that Trivex has over polycarbonate is that it can be easily tinted.

POLYCARBONATE

A polycarbonate lens is approximately 35% lighter and 25% thinner than a plastic lens. The lens is impact resistant which is great for kids and overall safety.

HIGH INDEX 1.67

A Hi Index lens is designed for high prescriptions and is made from the thinnest, lightest material available
