2. What is the progressive lens?
|
Modern progressive lenses, on the other hand, have a smooth and consistent gradient between different 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. Coating Choices:
YOULI optical lens has Uncoating, hard coating, hard multi-coating and superhydrophobic coating for your to choose.
------Hard Coating: The uncoated lenses are easily subjected and exposed to scratches, so the hard coating can help the lenses be destroyed.
------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 visual effect.
