Contact lens

Leonardo da vinci is the first to present the general peinciple of contacts in 1508, where he described a method of straight changing cornael power by dipping the eye in a dish of water.

A contact lens is a remedial, aesthetic or healing contact lens usually placed on the cornea of the eye. Get in touch with contacts usually provide the same remedial purpose as traditional cups, but are light and portable and almost unseen. It has been calculate that about 125million individuals use contacts globally. People choose to put on contacts for various reasons.

The features of contacts can be categorized as

Corrective contact lenses

Therapeutic contact lenses

Soft contacts are often used in the treatment and management of no n indicative problems of the eye. A bandage contact lens defends an harmed or infected cornea from continuous massaging of flashing eye covers thereby enabling it to cure.

Types of contacts by material

The first contacts were created of glass, which triggered eye pain, and so were not able to be used for long time times. The release of contacts created from polymethyl methacrylate(PMMA) becomes much more practical and these contacts are generally known as "Hard" contacts. However PMMA contacts doesn't transfer fresh air to the cornea which can cause a variety of negative clinicle activities.

In the delayed 1970 enhanced firm components which were also oxygen-permeable were developed. These contacts were known as RGP contacts. In effect, the contact lens is able to substitute the natural shape of the cornea with a new refracting surface area and provides good level of perspective in individuals wgo have astigmatism or altered cornael forms as with keratoconus.

The concept cutting-edge in smooth contacts created by Otto Wichterle led to the release of the first smooth contacts in the Nineteen-eighties. Soft contacts are instantly comfortable, while RGP contacts need a period of variation. The polymers from which smooth contacts are produced enhanced over the next 25 years, mainly in terms of increasing the fresh air leaks in the structure. In 199, plastic hydrogels became availabkle. Silicone contacts have very high fresh air leaks in the structure and were suggest mainly for extended(overnight) use. 

A daily use contacts is developed to be eliminated prior to sleeping. An prolonged wear(EW) contacts is developed for ongoing over night use, typically for 6 or more successive evenings. More recent components such as plastic hydrogels allow for even a bit longer of up to 30 successive evenings, these contacts were known as ongoing wear(CW).

The various smooth contacts available are often categorized by their alternative routine.More generally contacts are suggested to be discarded on a two week or monthly basis. Every quarter or yearly contacts, which are used to be very common, have lost benefit because a more regular convenience routine allows for slimmer and boundaries remains. Complecations due to contacts use impact approximately 5% of contact lens users each year. Extreme use of contact lens, particularly over night use. Problems associated with contact lens may impact the eye lid, conjunctiva and the various levels of the cornea.
