Polycarbonate is one of the strongest and safest materials on the market. They have exceptional strength and resilience.
- Excellent impact-resistance - 10 times more impact resistant than other lenses.
- Thin - About 20 to 25 percent thinner than plastic or glass lenses.
- Lightweight - About 20 percent lighter than plastic lenses.
- Blocks 100 percent UV rays without needing a special coating.
Trivex lenses offer superior impact resistance. It exceeds the FDA requirement for impact resistance. Due to the superior strength of Trivex, it makes a great choice for today’s stylish eyewear frames, many of which require drilling or grooving the lens. Trivex lens material also blocks out 100% of harmful UV rays.
Mid to High Index Plastic Lenses
Mid and high index lenses are for people with a high prescription. They allow spectacle lenses to be made thinner, lighter and flatter than previously possible. They are compressed lenses that offer better optical viewing through them. For higher prescriptions they not only reduce the weight by up to 50% but also reduce the thickness by up to 60% making them more attractive cosmetically. In addition to making the glasses look cosmetically better, they will feel lighter on your nose, and the flatter shape of the lens will make things look less distorted towards the edges of your lenses.
- Lightweight - Between plastic and polycarbonate lenses in weight.
- Thin - About 15 to 30 percent thinner than plastic lenses.
- Better peripheral optics than polycarbonate lenses (for prescription sunglasses).
Anti-Reflection Lens coatings improve both the vision you experience through your lenses and the appearance of the lenses themselves.
8% of light becomes reflections on uncoated lenses; these reflections interrupt your vision, making it less clear than with a coated lens. They are also distracting for people looking at you as they do not have a clear view of your eyes.
