1. Flat Top Bifocal Lenses
|When people inch closer to forty, they may find that their eyes are not adjusting to distances as they used to, the lens of the eyes begin to lose flexibility. It becomes difficult to focus on close objects. This condition is called presbyopia. It can be managed to a large extent with the use of bifocals. |
Bifocals are two lenses in one. They’re shaped differently at the bottom and top to help you see close up or far away. They come in both eyeglasses and contact lenses. Some bifocal glasses have a line across the middle that divide the two corrections.

Due to the light weight and flexibility of polycarbonate, these lenses are easier to remove and install than glass lenses, and are available in more styles of sunglasses that cannot accommodate heavy glass lenses.
