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 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. Photochromic lenses are available in both materials.
- Cost. The cost of polycarbonate and Trivex lenses can vary considerably, but many optical stores charge more for Trivex lenses than polycarbonate lenses.
