Lightweight Comfort

Last modified: 4/24/2009

Lenses made with Trivex material are ultra-light for ultimate comfort; Trivex is one of the lightest lens materials on the planet. And means eyewear  doesn't slide off the nose. Unlike other lens materials, Trivex blends the benefits of light weight and thinness, often resembling a high index lens, but weighing even less than polycarbonate.

 

Trivex® Standard Plastic

Specific Gravity: The lower the number, the lighter and more comfortable the lens will be. This number represents the relative density of an object to an equal volume of water. Anything with a specific gravity less than 1.0 will float on water. Although a high index lens appears to be thin and light, it actually has a higher specific gravity because it is made from a more dense material. On the other hand, a lens made from Trivex material is so light that it almost floats.
