---With progressive lenses, you won't need to have more than one pair of glasses with you. You don't need to swap between your reading and regular glasses.
---Vision with progressives can seem natural. If you switch from viewing something up close to something far away, you won't get a "jump" like you would with bifocals or trifocals. So if you're driving, you can look at your dashboard, at the road, or at a sign in the distance with a smooth transition.
---They look like regular glasses. In one study, people who wore traditional bifocals were given progressive lenses to try. The study's author said most made the switch for good.
1. Impact Resistant
Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
3. UV Protection
Polycarbonate lenses inherently carries UV protection properties that blocks nearly 100% of the UV rays from entering the back of the retina.
