Trivex High Index Lenses
Trivex is a relatively new plastic lens material that is being used as a substitute for polycarbonate lenses. Trivex is optically superior to polycarbonate and it is lighter. Like polycarbonate it provides 100% UV protection and it is extremely durable. Most importantly, Trivex is a great substitute for polycarbonate lenses that need to be tinted, because Trivex can be easily tinted but polycarbonate cannot. Trivex is much better suited for tinting and is an excellent choice for rimless drill mounted frames. The suggested prescription range is Plano (0, no Rx) to +/-8.00 sphere. Trivex may be slightly thicker than polycarbonate lenses, but due to its specific gravity the weight will be similar.
