Side Effects of Contact Lenses

The Effects of Long-Term Contact Lens Wear thumbnail

 Contact lenses are corrective plastic discs that are inserted on the eye's cornea to correct the wearer's vision. In some instances, people use contact lenses for cosmetic purposes, such as changing their eye color from, for example, gray to blue. Contact lenses have the same function as eyeglasses. Unlike eyeglasses, however, they are worn directly on the eye, are lightweight and almost invisible. Some side effects are occasionally associated with use of contact lenses.Contact lenses have become a welcome alternative to wearing prescription eyeglasses. But, concern has grown over the years about long-term contact use and its effects on overall human health


For those who have eyesight problems, contacts can help to clear vision by adhering to the outside of the eye, typically during the hours a person is awake. You can wear other contacts, such as extended-wear types, while sleeping.


  • Doctors are seeing various issues for long-term wearers of contacts. Some patients are experiencing vision loss due to bacteria that has contaminated the lens. Others are developing thinness of the cornea and aberrations in the eye surface.


Storing contact lenses in saline solution is very important to the cleanliness and function of contact lenses. All contact lenses, except for daily lenses and overnight lenses, must be stored in saline solution or a multipurpose solution. Saline solution cleans the lenses and prepares them to be reused. The lenses must remain in saline solution for a minimum of four hours to be effective. You may also want to consider multipurpose solution for storing and cleaning your contact lenses.
