Trivex monomer based on urethane to prepare lens passing impact strength of FDA standard (127cm, 16g).

Trivex lens monomer based on urethane to prepare lens passing impact strength of FDA standard (127cm, 16g) even in multi-coated completed lens, has the advantages as ophthalmic lens when making lens as follows.

- High impact strength of lens.

- High abbe value of lens in the range of 41-46.

- Clearness and high transparency of lens.

- Easy manufacture of rimless glasses.

- Protection of UV rays up to 400nm without a special treatment to lens.

Polycarbonate vs. Trivex Lenses: A Quick Comparison

- 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.
