Excellent optical materials with high refractive index. high abbe number. low specific gravity and high impact resistance are provided by polymerizing monomers of mr™ series. These lenses provide crisp optics. especially if shaped aspherically. but don’t have the impact resistance of trivex or polycarbonate.

The 1.61 high index lenses are thin and stylish. High index lenses polymers typically refer to products with an index higher than 1.58.

High index lenses are not naturally impact resistant. Because they are typically processed to be as thin as possible. and because high index is a plastic that will crack when enough force is applied. many pairs of high index prescription lenses would fail an impact resistance test.

With higher prescription powers. peripheral vision may be slightly less clear. Most high index plastics rate relatively the same for scratch resistance. and any high index plastic is going to be more scratch resistant than standard plastic or polycarbonate.

Learn which lens index and material is best for you based on prescription. frame and lifestyle. Mr™ series is especially suitable for ophthalmic lenses and is known as the first thiourethane based high index lens material.
Polycarbonate Lenses Have Superior Impact Resistance And Are Lighter Than Regular Plastic Lenses.
Highly recommended for active eyewear. What are the benefits of polycarbonate lenses? They’re also ideal for strong prescriptions since they do not add thickness when correcting vision. minimizing any distortion.
Most High Index Plastics Rate Relatively The Same For Scratch Resistance. And Any High Index Plastic Is Going To Be More Scratch Resistant Than Standard Plastic Or Polycarbonate.
Our eyeglass lenses are 20% thinner. Mr™ series offers a variety of products to. Boast scratch resistance so they last longer than regular plastic lenses.
These Lenses Provide Crisp Optics. Especially If Shaped Aspherically. But Don’t Have The Impact Resistance Of Trivex Or Polycarbonate.
Furthermore. aspheric curves come standard in many high index products. particularly 1.66 and 1.70 products. and are available in. Trivex is more impact resistant than high index plastic. making it a much better choice for safety glasses or other types of glasses that need to meet certain impact. High index lenses are not naturally impact resistant.
However. Labs Would Generally Surface This Material Down To 1.5 Mm And Then Perhaps Add An Ar Coating To It.
Excellent optical clarity even for higher powers. It is an innovative material for lenses that offer a balanced set of characteristics—thinness. light weight. break resistance. and perfect clarity—demanded by many eyeglass lens users around the world. 10 times more resistant to impact than plastic eyeglasses. so they don’t shatter or break as easily.
