The Basics of Sclera Contact Lenses

Sclera contact lenses are not very common these days, but are used sometimes for particular vision conditions. Sclera lenses are larger than conventional lenses and cover the sclera, which is the white part of the eye. These are the oldest type of contact lenses and are used occasionally when other types of lenses cannot be used.

One reason why you might need this type of lens is if you have a condition called keratoconus. Keratoconus occurs when the center of the cornea is thin and protudes outward, affecting the eye's ability to focus properly. Whether or not you will develop this condition is a trait present at birth and affects approximately one in every two thousand individuals. If glasses or other types of contacts do not work for you, your eye doctor may recommend sclera contacts. One benefit of these contacts is that they are easy to handle, due to their large size. However, they have downsides as well. One is that the transmission of oxygen to the eye is reduced, which can lead to problems. Also, this type of lens is quite time-consuming and difficult to fit as compared to conventional contact lenses.

Some people choose sclera lenses for cosmetic purposes rather than medical purposes. Some theatrical and special effect lenses are scleral in nature so that the effect covers the entire surface of the eye. Usually, the use of this type of novelty lens is discouraged because of the various drawbacks. Luckily, people who want special effect lenses have other options from which they can choose.

If you are simply seeking special effect contact lenses that offer no vision correction, you might want to check out the choices available at Lenses by Mail (http://www.lensesbymail.com). Their Wild Eyes collection is made by Ciba and offers a variety of wild contact lens choices. For a mysterious all-black look, go for the Black-Out lenses. There are White-Out and Red-Out lenses which change the color of the iris to bright white and scarlet red, respectively. For a fierce feline look, try the Cat Eye or Jaguar contacts. No matter what kind of theatrical look you desire, there is an option for you. These lenses are monthly disposables, which make them safer to wear than sclera lenses.

If you want colored contacts or traditional soft contacts, Lenses by Mail has those as well. They offer fast shipping and even a satisfaction guarantee to their customers. Always consult with your eye doctor if you want or feel you need sclera contact lenses or any other kind of lenses. Your eye care professional can inform you of all the risks and rewards of various types of contacts so you can make the best choice for your needs.
