Lenses do not regulate vision, but some progressive lenses can help the ciliary muscles to adjust. The quality of the lens is mainly determined by the transmittance, the surface, the aspherical surface, the refractive index, the coating quality.

Who need progressive lenses?
There is no limit to the degree of progressive multifocal lenses. Whether it is nearsightedness, presbyopia or moderate astigmatism, it can be worn, but not everyone can wear it. There are two types of progressive multifocal lenses on the market, one is hard and the other is soft. The main difference between the two designs is the length of the progressive channel. The rigidly designed progressive film has a short progressive path and relatively less peripheral aberrations. In order to ensure vision at various distances, fewer vertical dimensions are required. For example, a teenage progressive film belongs to this design, but because of its short gradual path, the gradation process is too short. Fast. Compared with the elderly, this design is more difficult to adapt; the soft design of the progressive film has a relatively long gradation channel and relatively large peripheral aberrations, but due to its long gradation channel, the gradation process is relatively smooth, which makes it easy to wear glasses It is suitable for people with poor adaptability.

When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing an object through the blurred vision area around the lens makes the object blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-use zone, the near-use zone, and the middle-distance zone to see objects.
