Glass

Glass is the LEAST shatter resistant and heaviest material in today’s market. Glass WILL shatter when struck by certain objects. Know that there is a risk factor when wearing glass lenses. Nonetheless, it still has its place. Glass has the best scratch resistant properties along with excellent optical quality.

High Index 1.67

High Index 1.67 lenses are for those with moderate to high prescriptions. The higher the Index of refraction, the thinner the lens. 1.67 is yet another lens that does well with rimless eyewear. Anti-reflective coating is highly recommended for 1.67 lenses. 1.67 will accommodate prescriptions in the +/- 6.00 range and sometimes higher. UVA and UVB protection is inherent within the lens.

High Index 1.74

High Index 1.74 index lenses are the ultimate in thickness reducing resin lenses. In some cases up to a 40% thickness reduction over standard lenses. Anti-reflective coating is included. 1.74 is the best choice for a cosmetically appealing thin lens. UVA and UVB protection is inherent within the lens.

Trivex®

Trivex® like polycarbonate has high impact resistance properties and inherent UV protection. Also excellent for rimless eyewear, in particular drill mounts, . Trivex® has less chromatic aberration than poly providing slightly better optical clarity. Its lower index of 1.523 will make it slightly thicker than poly with the same RX. Trivex® is recommended for prescriptions up to +/-3.00.

Polycarbonate

Polycarbonate (poly) is known for its high impact resistance properties. Slightly lighter in weight than CR-39, poly is also a thinner material than plastic, glass or Trivex®. Poly is a great candidate for rimless frames. When lens thickness is a concern, poly is recommended for prescriptions up to +/-4.00

Plastic

Plastic lenses, sometimes referred to as CR-39 is a lighter in weight alternative to glass. Also more impact resistant than glass, however with much lower scratch resistance properties.
