Polycarbonate vs. Trivex Lenses: A Quick Comparison
Here is a brief comparison of polycarbonate and Trivex lenses to help you decide which lenses might be best for you:
Thickness. Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses.
Weight. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses.
Optical clarity (central). Trivex lenses have less internal stress and may produce sharper central vision than polycarbonate lenses.
Optical clarity (peripheral). Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses.
Impact resistance. Polycarbonate and Trivex lenses have comparable impact resistance.
UV protection. Polycarbonate and Trivex lenses both block 100 percent of the sun's UV rays without the need for special UV-blocking lens coatings.
Availability. Polycarbonate lenses are available in a wider variety of lens designs (e.g., progressive lenses and other multifocals) than Trivex lenses.
Cost. The cost of polycarbonate and Trivex lenses can vary considerably, but many optical stores charge more for Trivex lenses than polycarbonate lenses.
