If you have chosen to use contact lenses instead of glasses, the next step is to choose the type of lens that suits you. There are two types of contact lense that are now available on the market, namely soft contact lenses and hard contact lenses. Of course before stabilizing to buy, you must first know what is the difference between a soft lens and a hard lens. Here are the advantages and disadvantages of each type of lens that you need to know.
What is a soft lens?
Soft lenses or soft contact lenses are soft contact lenses, made of soft and flexible plastic that allows oxygen to easily penetrate the cornea. The newer soft lens material is usually made of silicone-hydrogel, which allows more oxygen to enter the eye as long as you use the lens.
Soft lenses include extended eye-wear contact lens types. That is, this lens can be worn continuously for a specified usage period (for example 7 days to 30 days) and then discarded. However, the continuous usage period will depend on the type of lens and evaluation of the doctor during routine eye checks.
There are two types of loft lenses. "Disposable" or one-time use, which means the lens must be used only once and then discarded and replaced the new one for the next use. There are also those with recipes so they can be used for a full day. This type of lens can also be used overnight, but must be replaced with a new pair every day.
What is a hard lens?
Hard lenses or rigid gas permeable contact lenses (RGPs) are a type of contact lens that is harder and stiffer than a soft lens, but can still let oxygen get into the eye. Generally, hard lenses provide a clearer and sharper vision than soft contact lenses.
In addition, hard lenses tend to require less maintenance costs because the duration of use is more durable than soft lenses and is more resistant to accumulation of dirt deposits. Therefore, the schedule for replacing this "hard" lens will be longer than the soft lens.
