The difference between large diameter and small diameter beauty contact lenses. What diameter do normal people wear?

When choosing cosmetic contact lenses, in addition to the color and degree, another factor that is easily overlooked is the diameter of the contact lenses. This will directly affect the effect of the contact lenses on the eyes and the comfort of the eyes. So what is the difference between large diameter contact lenses and small diameter contact lenses?

Suitable for different groups of people and different oxygen permeability. Everyone likes different styles of contact lenses. Some people like large diameters, some people like small diameters, but liking is useless. The diameter is related to the size of the eyes.

Large-diameter lenses are suitable for wearers with big eyes, while small-diameter lenses are suitable for wearers with small eyes. If the large and small diameter lenses do not match the size of the eyes when worn, it is easy to cause lens slippage, bubbles to appear, block vision, and even damage the cornea.

Generally, when you buy cosmetic contact lenses or cosmetic lenses, the diameter is 13.8mm 14.0mm 14.2mm 14.5mm or above 14.5mm. This diameter is considered a large diameter product. Most people should not try it easily, otherwise, it will easily turn out that the size does not match after purchase.

The oxygen permeability of large-diameter cosmetic contact lenses is worse than that of small-diameter ones. Because the diameter of large-diameter cosmetic contact lenses is very large, it will affect the mobility of the lenses, making the transparency effect worse.

For small eyes, 14.0 and below are recommended, collectively referred to as small diameters, which are suitable for small eyes! The diameter of cosmetic contact lenses is also divided into solid diameter and tinted diameter! ! For example, the diameter of a tinted lens with a diameter of 14.5mm is only 14.0mm, and the diameter of a tinted lens with a solid diameter of 14.2mm is also 14.0mm, which means that the two diameters are the same, so the effect of cosmetic contact lenses on the eyes mainly depends on the size of the tinted diameter.
