Contact lenses, whether soft or hard, are designed to correct the vast majority of visual defects: myopia, hyperopia, astigmatism, presbyopia, and so on. Choosing to wear them requires knowing the right way to put them in, to remove them, and maintain them properly.

What kind of contacts is right for you?

There are two main types of lenses: soft and hard. An ophthalmologist, depending on the specific characteristics of your eye and your lifestyle, will determine the type of lenses that are best for you.

Soft lenses consist mainly of water and will function as sponges. Their hydration depends on the wearer’s production of tears. For example, insufficient tear production leads to dry eyes. Their comfort is felt from the first moment they are put in, and their frequency of renewal varies according to their category:

  • Daily disposable lenses are for single use, meaning you wear them during the day and throw them away at night.
  • Lenses with frequent renewal can be kept in from two weeks to three months, and require daily maintenance.
  • Traditional lenses must be renewed every year.

Recently, the industry has come up with new soft silicone hydrogel lenses. They are much more breathable than traditional soft lenses. This means that a more significant amount of oxygen passes through the lens to feed the cornea. They are more comfortable. These lenses require specific cleaning products.

Colored soft lenses are used for cosmetic purposes: to change eye color. They may or may not be correcting lenses. In any case, they require rigorous amount maintenance and the wearer must respect the rules of hygiene. Note: they can reduce night vision.

Hard lenses

Hard lenses, called “gas-permeable,” are composed of materials that let oxygen pass through the eye: an essential asset that lets the cornea breathe. They are generally used in people who suffer from dry eye. These lenses are more perceived by the eyelid, which can cause tears and blinking.

Gradually, after several days, this discomfort disappears. The frequency of renewal varies from one to two years. To learn more, visit econtactlenses.com.au or contact a local ophthalmologist or optician.
