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.

The perception of space has changed, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do strenuous exercise. 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.

How To Use Contact Lens Correctly?

Check your eyes for abnormal cases. Do your eyes sting or dry? If so, it is recommended not to wear contact lenses for the time being. Look in the mirror to see both eyes carefully, if it is red and swollen or if is both eyes full of bloodshot? If you do, you can no longer wear contact lenses, and you can go to a professional store for inspection. After putting on the contact lenses, block the left and right eyes respectively to see if the vision of one eye is clear. If the eye vision has decreased or blurred, check if the lens is dirty. If the lens is still the same, you should go to a professional store to find out the reason.


Anti-fouling Coating

The lens coated with anti-reflection film is pretty prone to stain, and the stain will affect the transmittance of the lens. Microscopically, the anti-reflection film shows a porous structure, therefore, the oil is very easy to soak in it. The solution is to coat a layer of anti-fouling film with anti-oil performance on anti-reflection film. The film is very thin and will not change the optical performance of the anti-fouling film. The material is mainly fluoride. There are two processes, one is the immersion method, one is the vacuum coating method (the most commonly used).
