What Is Progressive lens?
The English term of progressive lens: Progressive lens, is a multi-focal length lens, which is different from traditional reading glasses and bifocal reading glasses. When the progressive lens does not have a bifocal type, the eyeball must constantly adjust the focus of the eyeball. The obvious dividing line between the focal lengths. It is comfortable to wear and has a more beautiful appearance. It has gradually become the best choice for people with presbyopia.
Progressive lenses are developed on the basis of bifocal lenses. The usage rate in Europe and the United States is relatively high, and the time for domestic inspection in China has only begun in the past 10 years. The progressive lens is the use of polishing technology to gradually transition between the two focal lengths in the transition between the upper and lower focal lengths, which is the so-called progressive. It can be said that the progressive lens is a multi-focal lens. When the wearer observes far/near objects, apart from not having to remove the glasses, moving the line of sight between the upper and lower focal lengths is also gradual. There is no fatigue that the eyeball must constantly adjust the focal length when using the dual focal length, and there is no difference between two focal lengths. The obvious dividing line between focal lengths. The only disadvantage is that there are different degrees of interference areas on both sides of the progressive film, which will make the peripheral vision feel swimming.
