Make Beautiful with Contact Lense

The history of Contact Lenses as a means of replacing the eyeglasses for the eyes and for providing a comfortable vision for the cornea goes back many years. They had originally been suggested by Leonardo Da Vinci, but the first instance of a contact lenses being built and used was in 1887. F.A.Muller of Germany made a transparent cover for a cornea which was diseased. The next year A.E.Fick, a physiologist of Zurich, moulded a set of lenses for his eyes, but he was unable to wear them for more than two hours.

Today, contact lenses are standard equipment for the eyes, not only as a transparent covering for the corneas, and also for their convenience and aesthetic value. They help your eye sight, look great and over the years have become very easy to use. They help your eyes by giving them a clear vision, and they do not alter your appearance as the spectacles do. They are made of various materials, and are available in many colours. The new materials do not impede the oxygen flow to the cornea, a problem that used to cause a lot of discomfort to the eyes, and specially to the corneas of sensitive eyes.

The optic nerve begins at the head of the retina as an optic disk, and transmits messages from the retina of the eye to the brain. These messages result in the visual images that we see. The optic nerve is the only extension part of the brain that can be viewed albeit through an ophthalmic instrument. It is a part of both the eye and the brain. Contact lenses today are being improved every year so that every part of the eye and eyesight are treated and assisted in their functions.

Contact Lenses are also being used to cure or help many vision problems such as myopia, apart from being the most popular form of vision correcting instruments. Almost 33% of the world 's population suffers from myopia - or near-sightedness as it is commonly known as. They are able to read or see images which are close to them, but unable to see clearly anything that is beyond a certain distance. Contact lenses have been very effective in helping people who have eye lens myopia.

Another new technique to cure myopia is known as orthokeratology. Approved in 2002 by the FDA, it involves wearing cornea shaping lenses at night. During the daytime you can move around without the lenses or spectacles on your eyes, since the cornea temporarily retains the shape of the CRT lenses.
