But what kind of contact lens is good? Especially for people who buy contact lenses for the first time, they don't know what kind of contact lenses are good. But don't worry, I will teach a friend how to choose the contact lens that suits him. From the perspective of the wearing cycle of contact lenses, contact lenses have different cycles such as daily, annual, and monthly, and each cycle has its characteristics. Therefore, the answer is not unique to what kind of contact lens is good; for example, daily disposable contact lenses are healthy and comfortable, but because the lenses are too soft, they are not suitable for first-time wearers, but regular wearers think that daily disposable contact lenses are very good. From this point, we can see that everyone has different ideas about which contact lens is good. From the perspective of oxygen permeability, contact lenses with higher oxygen permeability are definitely better. We know that when wearing contact lenses, the amount of oxygen the cornea of u200bu200bthe eye obtains will be reduced. The reason is that the contact lens lenses will To prevent a part of the oxygen from entering, the higher the oxygen permeability of the contact lens, the more oxygen the cornea gets, so that the metabolism of the cornea will be more normal and the eyes will naturally be healthier. From the perspective of water content, this is one of the important parameters of contact lenses.

There are also many brands of contact lenses, such as Johnson u0026 Johnson, Bausch u0026 Lomb, Haichang, etc. Bausch u0026 Lomb contact lenses are an early brand that entered the Chinese eyewear market, and many people wear them. However, some people still say that Bausch u0026 Lomb contact lenses are not good. There have been cases of return and exchange in the professional contact lens mall, but it is not that this contact lens is not good, it can only be said that it is not suitable for this contact lens. So what kind of contact lens is good also depends on the brand that everyone can adapt to. Many consumers will ask businesses what contact lenses are good when buying contact lenses, and some businesses will recommend contact lenses with higher sales to customers. In fact, this is unscientific. Everyone's eyes are different, and the suitable contact lenses are also different; so we should start from our own situation.
