Years ago, glass was the only option available for lenses, but today a wide range of lens materials are available to match all lifestyles. In fact, less that six percent of glasses sold today are made of actual glass. Your personal lens material selection will depend on your level of activity, comfort, vision needs and the recommendation of your eye care provider.
The lenses you choose for your prescription eyewear – even more than the frames – often determine how happy you are with your eyewear. When buying prescription eyewear, the frame you choose is important to both your appearance and
your comfort when wearing glasses. But the lens material influence four factors: appearance, comfort,
vision and safety.
Ultimate Optical offers a comprehensive range of spectacle lenses which are available in the following
types, materials and coatings:
Lens Types:
• Single vision lenses
• Bifocal lenses
• Multifocal lenses
Lens Material:
• Trivex - Trivex lenses are made of an exceptionally clear, lightweight lens material, which translates
into excellent all-day wearing comfort. So you can experience superior eye protection, sharp vision
and lightweight comfort — all in the same lenses.
• Polycarbonate - While its optical characteristics are less than ideal, polycarbonate, the same
material used for bullet-proof glass, is the most impact resistant of lens materials.
• CR39 - Developed by PPG during WWII, CR-39, also known as plastic or hard resin, serves as a
much lighter lens material (approximately 50% lighter) than glass. CR-39, however, is far less scratch
resistant and often must be coated to improve its scratch resistant characteristics.
• Glass - Glass has historically been the material of choice for ophthalmic lenses. Glass is most
stable, scratch-resistant, and provides the best optical quality of all lens materials.
Coatings and treatments:
• All lenses are UV resistant up to and including 400nM
• Anti-scratch
• Photochromatic (Transision) lenses (optional coating)
• Anti-reflective (optional coating)
