2. What is the progressive lens?
| Modern progressive lenses, on the other hand, have a smooth and consistent gradient between differing lens powers. In this sense, they can also be called “multifocal” or “varifocal” lenses, because they offer all of the advantages of the old bi- or trifocal lenses without the inconveniences and cosmetic drawbacks. |  |
3. Why we choose the photochormic progressive?
With progressive lenses, no one has to know whether you're wearing glasses just for fashion — or because your arms have "grown too short" for you to see up close.
When you go the outdoor, the stong sunlight is harmful to your eyes. You do not need to change another new sunglasses to wear to protect you. The photochormic progressive lenses can turn the "sunglasses" directly to protect you in the sun. It is so convenient.
III. Coating Choices:
Aogang optical lens has Uncoating, hard coating, hard multi coating and super hydrophobic coating for your to choose.
------Hard Coating: The uncoated lenses are easily subjicted and exposed to scratches, so the hard coating can help the lenses be destoried.
------EMI Coating : It also called AR coating or hard multi coated/coating, means coat another anti-reflective coating on the hard coating . It can perfectly reduce harmful ray and enhance the vision effect.
