Progressive lenses are developed on the basis of bifocal lenses. That is to say, in the transition between the upper and lower focal lengths, the grinding technology is used to gradually transition between the two focal lengths, that is, the so-called progressive. It can be said that the progressive lens is a multi-focal length lens. When the wearer observes far/near objects, in addition to not having to remove the glasses, the movement of sight between the upper and lower focal lengths is also progressive. That clear dividing line between focal lengths. The only disadvantage is that there are different levels of interference areas on both sides of the progressive film, which will create a sense of swimming in the peripheral vision.

Production Introduction

What are progressive lenses?

Wearing progressive lenses helps the wearer see clearly at any distance without the need to change glasses. Progressive lenses are an alternative to bifocal or trifocal lenses to correct refractive errors such as presbyopia (farsightedness that develops with age and is a common problem in people over 40).

The principle of progressive lenses

Progressive lenses have different power zones from top to bottom on the front. The seamless connection between the powers of the lens allows the wearer to look straight ahead to see distant objects, look down to see objects at intermediate distances, and look down to help the wearer read or perform other activities that use near vision without having to change many pairs glasses.

Advantages of progressive lenses

People often choose progressive lenses for aesthetics, as two areas of different power can be clearly seen from a bifocal (or trifocal) lens. Progressive lenses replace this design with seamless power changes, avoiding the visual incoherence caused by moving the gaze up and down when wearing bifocal or trifocal lenses, and can really help the wearer improve vision.
