If you've made a choice of using contact lenses instead of glasses, the next step is to choose the type of lens that suits you best. Now there are two available types of contact lenses on the market, namely soft contact lenses and hard contact lenses. Of course before you make the decision, you should know first what is the difference between soft lens and hard lens. Here are the advantages and disadvantages of each type of lens you need to know.
Soft lenses or soft contact lenses are a type of soft contact lens that made of soft and flexible plastic that allows oxygen to easily penetrate the cornea. Newer soft lens materials are usually made of silicones, allowing more oxygen to enter the eye as long as you wear the lens.
Soft lenses are extended eye-wear contact lenses. That is, this lens can be worn continuously for the specified usage period (eg 7 days to 30 days) and then discarded. However, the life span usage will depend on the type of the lens and doctor's evaluation during eye routine checks.
There are two types of soft lens. Disposable, which means the lens should be used only one time then discarded and replaced by a new one for subsequent use. There is also a prescription so that soft lens can be used for a full day. Soft lenses of this type can also be used in a day and night, but must be replaced every day.
Rigid Gas Permeable contact lenses (RGPs) are harder and more rigid contact lenses than soft lenses, but still allow oxygen to enter the eye. Generally, hard lenses provide clearer and sharper vision than soft contact lenses.
In addition, hard lenses tend to require less expensive maintenance costs because the it is more durable than soft lenses and more resistant to the cumulation of dirt deposits. Therefore, this hard lens replacement range time will be longer than soft lenses.
