Types of contact lenses

Contact lenses are a great alternative to glasses and offer many benefits. Besides being cosmetically useful, you don’t have the hassle of them sliding up and down your nose, fogging up every time you come out of an air-conditioned room or being a hindrance while you are playing a sport. There are several types of contact lenses available in the market today. Read more on specialized uses of contact lenses.

Soft contact lenses:

These are the most popular and commonly used lenses. Soft contacts are made of a soft plastic that contains a high amount of water, the primary purpose of which is to allow oxygen to pass through to the eye. They also tend to be more prone to infections and must be removed before sleeping at night.

Hard contact lenses:

These are made of a more rigid type of plastic than soft lenses, and therefore tend to be somewhat less comfortable than soft lenses. Though they take a while to fit in, by virtue of being hard, they are sturdier than soft lenses and easier to keep clean as well. Hard lenses allow for reduced amounts of oxygen to enter the eye and must be taken out at night and cleaned properly.

Rigid gas-permeable lenses:

This is a type of hard contact lens that allows more oxygen to the eye than regular hard lenses. If you have astigmatism which is a condition wherein the cornea is irregularly shaped, making it difficult to focus the option of wearing rigid gas permeable lenses is highly recommended.

Extended-wear lenses:

These are special lenses have been designed so that they can be worn for several consecutive days without having to take them out at night. Although these extended-wear lenses offer certain conveniences, they are also prone to eye problems such as infections of the cornea.

Disposable lenses:

Disposable lenses are lenses that are designed to be worn for a certain period of time and then disposed off. These are available on a daily, weekly, or monthly basis, depending on the type your eye doctor recommends for you. Their main benefit is that they carry little chance of infection or protein build-up as they are worn for shorter periods.

Cosmetic lenses:

These contact lenses alter or enhance the appearance of the eye colour. These can look very natural and can make light-coloured eyes look darker or dark-coloured eyes look lighter.
