There are many types of contact lenses, which can be classified in different ways, and the price ranges from tens of yuan to hundreds of yuan. The editor saw that many people have doubts about the price of contact lenses. In fact, there are many factors that affect the price of contact lenses. Today, we will introduce a little knowledge in this area.
There are many brands of contact lenses on the market, and there are products with good reputation to choose from in different sales channels. Different contact lens brands also have big differences in price, and even if it is the same brand, the prices of lenses between different series are somewhat different and cannot be generalized.
According to the material of the lens, contact lenses are divided into soft lenses and hard lenses, both of which are made of polymer compounds with strong water content. Among them, hard lenses are only fitted in eye hospitals, and the process of fitting glasses is strict, so the price is relatively high, generally costing several hundred to several thousand yuan. The soft mirrors that everyone usually uses need to be produced and sold with a license, and they can be purchased online and online. The material of the soft lens is also divided into two categories: hydrogel and silicon hydrogel. Among them, silicon hydrogel is an upgraded version of hydrogel and has dual oxygen-permeable channels, so the price is slightly higher.
Under normal circumstances, for long-term cycles such as annual and half-yearly throws, the specifications are mostly one-piece or two-piece packs, and the shorter the throwaway specifications, the greater the number, and the daily throw may be as high as 30 pieces. On average, contact lenses with a long cycle are more cost-effective, but it should be noted that in most cases, a bottle of care solution is needed to protect the lenses.
In addition, routine inspections before glasses are also very important. It is necessary to check whether the wearer has eye diseases and whether it is suitable to wear contact lenses, so as not to aggravate the condition or affect the treatment.
