Some people are not clear about what types of contact lenses are available on the market. One of the types is disposable contacts, which are commonly seen on television commercials and Internet ads. This article describes basic types of contact lenses. Before making a decision, contacts wearers should carefully evaluate these factors including lifestyle, budget and so on. In addition, the best, most personalized decision can be made only with a detailed discussion with an eye professional.
Soft lenses are made of flexible plastic. This material is soft and permeable that allows oxygen to pass through and reach the cornea. It is commonly known that soft lenses are easier to adapt to. Moreover, soft lenses are always more comfortable than other types and most disposable contacts belong to the soft type.
One of the widely accused disadvantages of rigid gas permeable contacts is that they are less comfortable than soft lenses. Nevertheless, RGP lenses also have good sides. They are more durable and resistant to deposits built-up. With this feature, wearers need not to worry about damaging and tearing while handling these lenses. In addition, RGP lenses are said to provide clearer, crisper vision than soft lenses.
Extended wear lenses can be worn continuously without removal for several days, which is the most significant difference between this type and daily wear lenses. Certain brands of extended wear lenses are even approved to last continuously 30 days. Some people always forget to remove their contact lenses and extended wear lenses are their best choice.
Also called replacement schedule lenses, disposable lenses can be less or more frequently replaced according to the lens type. To the extreme, daily disposable contact lenses can be worn and discarded every day. Most types of disposable contacts are intended to last a couple days and then be discarded.
Customers should look into all the benefits and drawbacks of each type of contact lenses. The final decision should be made between a customer and his eye practitioner. In general, daily disposable contact lenses are more suitable for those who are susceptible to eye infections.
