People who are reluctant about following instructions regarding the proper use of contact lens are on the other way increasing the risk of even blindness.
Improper way of using contact lens can generate serious eye infections and that can lead to blindness.
Modern contact lenses fall into two categories: soft lenses that are made from water-containing plastics, and GP or "oxygen permeable" rigid contact lenses.
Contact lenses may also be classified by wearing schedule. Daily wear contacts must be removed, cleaned and stored each night, while extended wear contact lenses are made from materials which are safe for sleep. You may also have heard of "continuous wear" contact lenses, a type of extended wear lens that can be worn for up to 30 days.
Various contact lens designs are available for different vision problems. Spherical contact lenses correct nearsightedness or farsightedness and are indicated by a minus or plus in your prescription, respectively. Bifocal contact lenses are similar to multifocal eyeglasses in that they use different optical zones to correct presbyopia (the decreased ability see at both near and far distances). Toric contact lenses correct astigmatism, which can accompany either nearsightedness or farsightedness.
FDA requests to follow these short and simple guidelines for good contact lens care to extend the life of your contact lenses, and protect the safety and health of your eyes.
* Do not top off or reuse lens cleaning solution;
* Use a contact lens solution to clean, rinse, and then air dry contact lens cases after each use;
* Do not expose contact lenses or lens storage cases to any type of water or other non-sterile solutions.
FDA has developed a new video on contact lens safety, which can be found on the FDA's Web site, along with an in-depth Consumer Update article, to support proper cleaning and storage of contact lens.
The video and the article stress the importance of emptying the solution out of the contact lens case after each use and using the rub-and-rinse method for added effectiveness.
