What Are The Advantage Of 1.56 Progressive Lens?
Dec 18, 2017

Also known as 1.56 progressive multi-focal lenses, it is used to slow the visual fatigue and control the development of myopia. Progressive lens is equivalent to the effect of the two lenses of different degree to integrated on a pair of glasses. 1.56 progressive lens is upper myopic degree by far, the lower part of the low degree of 50-200 degrees, but both sides have a "twilight zone", so using peripheral vision to see things is not clear and even distorted which cannot be used for sports and driving. I think it's better to have two glasses, but you need to know what to wear. Use the correct number to see if you can reduce your glasses by 50 to 200 degrees. It's a bit of a hassle but it's the best thing. The processing of 1.56 progressive is more important than the quality.
