If so, then you should consider polycarbonate lenses, which are ten times more impact-resistant than plastic or glass lenses. While impact resistant doesn't mean shatterproof, it does offer an extra level of protection for an active lifestyle. Adding an anti-reflection to your lenses allows more light to reach your eyes. The result is that you can see better in low light situations, such as driving at night. You also look better because people can see your eyes without those annoying reflections.
Progressive lenses provide more natural vision at all distances without the old-style bifocal lines.
Progressive lenses help eliminate the image jumping that occurs in bifocal and trifocal lens designs. High-index lenses provide more comfort and better looks. They're thinner so you can have slimmer glasses. They're lighter, so they're more comfortable to wear. And because lenses won't bulge from the frame, your eyes will appear less magnified and more natural.
