Contact lenses have proven over the years how useful they are in managing vision problems for countless patients around the world. More patients who have gone to the Cornea Consultants of Arizona have switched to wearing contact lenses from conventional eyeglasses because they are the better-looking, more versatile alternative for vision correction. But before you head on out and get yourself a pair, here are some facts about them that may be helpful when choosing the right one for you.

Soft contact lenses are available in three main types namely daily wear, extended wear, and disposable lenses.

  • Daily wear lenses are worn during the day and removed at night before sleeping so they can be cleaned and disinfected. They are also the least expensive option.
  • Extended-wear lenses can be worn even during sleep and only require cleaning and disinfecting at least once weekly.
  • Disposable soft lenses are the most expensive option for soft lenses. They can be worn daily and do not require removal at night, nor do they require regular cleaning. They are simply worn for the recommended time and then discarded, making them more convenient for the user.

Hard contact lenses are the more permanent alternative to soft contact lenses. They are more rigid, but provide a higher degree of correction for most vision difficulties and also reduce the risk of eye infections because they are more “breathable”. The adjustment period for hard contact lenses may take about a week, during which time the patient may feel some level of discomfort as they get accustomed to the appliance. This type of contact lens requires nightly cleaning and disinfecting but can last for up to three years with proper care.

Nowadays specialized contact lenses are available in the market, including:

  • Hybrid contact lenses are a combination of a hard center lens enclosed by a soft outer ring.
  • Multifocal contact lenses are versatile lenses that can correct nearsightedness, farsightedness, astigmatism, or presbyopia.
  • Tinted contact lenses are available to enhance color perception or correct color blindness. Most tinted lenses today, however, are used for cosmetic purposes but should be used with care as these could potentially cause infections.
