Wholesale Price 1.59 PC Polycarbonate HMC AR Coating Flat Top Bifocal Optical Lens

PC flat-top bifocal lenses not only possess some advantages of PC material, such as light weight and strong impact resistance, but also have the advantages of bifocal lenses in terms of optical performance: one lens integrates two different optical zones, one for near vision (such as reading or writing), and the other for distance vision (such as watching TV or driving), allowing users to meet the visual needs at different distances without frequently changing glasses.

Features of Wholesale Price 1.59 PC Polycarbonate HMC AR Coating Flat Top Bifocal Optical Lens

1. High impact resistance

PC's impact resistance is about 10 times that of ordinary resin lenses, making it ideal for athletes, children, and anyone who needs to perform high-intensity activities.

2. Very lightweight

The density of the PC material is low, so the lens made is very light and comfortable to wear.

3. UV protection

PC material has a natural anti-ultraviolet function, which can effectively block more than 99% of harmful ultraviolet rays.

4. High transparency

Although PC material is relatively hard, but its optical transparency is very high, can provide clear visual effects.

5. It does not turn yellow easily

Ordinary resin lenses are easy to yellow, and PC lenses are not easy to yellow.

Advantages of Wholesale Price 1.59 PC Polycarbonate HMC AR Coating Flat Top Bifocal Optical Lens

The difference between round top bifocals and flat-top bifocals in the method of determining the machining reference line and the apex of the sub-lens, as well as the suitable eye distance. The difference between the invisible bifocal and the other two is its appearance, the invisible bifocal fuses the small lens in the large lens, and there is no obvious boundary between the size of the lens, which does not affect the appearance. However, this design will also lead to the inevitable phenomenon of image jump and image defect.
