Bifocal lenses are primarily required for correction of presbyopia. The vision of both the far and the near can be corrected at the same time. The top is the luminosity used for the far side, and the lower is the luminosity used for the near view. The difference between the upper and lower luminosity is called ADD.

Ordinary presbyopic lenses have a close view clearly and unclear far-sighted, requiring you to frequently wear glasses. The bifocal lenses are aimed at the eye features of presbyopic patients, and the use of the extended light zone technology is ingenious, and the visual range is wider, and it is easy to have a good far and close vision.

1. The ultra-hard top coating treatment process makes the coating toughness and greatly improves the hardness. Waterproof, super anti-stain and anti-glare.

2. The new design based on a physiological flat base bends to ensure the comfort you wear, the lenses are flatter, thinner and lighter.

3.Light weight, super anti-scratch and high safety. 

4.The TCM coating layer process on the lens surface facilitates processing and better protects the lens.
