Contact Lenses Makes Life So Much Easier

In 1508, Leonardo da Vinci described and drew the sketch to express his idea of a contact lens. But it was Sir John Hershel, an English astronomer in 1827, who astounded the world with his idea of making a mold of a human eye so that a lens could be made to fit perfectly. And in 1887, sixty years later F. A. Muller, a German glassblower used these ideas to create the world’s first known contact lens.

Contact lenses are full contact optical accessories which rest directly on the cornea to ease a better and natural vision than contemporary glasses. Distortion due to side vision and eye-lens distance is voided in using contact lenses. With glasses the eye-lens distance makes the size of the objects appear bigger or smaller than actual depending upon whether you are far sighted or near sighted.

One problem with eye glasses is that they block the peripheral vision due to the frame. When you are looking sideways, upwards or downwards, you are looking outside the perimeter of the lens which makes you look at object without the eye glasses resulting in distorted or blurred vision because you are not looking through the optic zone.

This is more so because of the smaller frames in style today. Now, when you wear contact lenses, regardless of which way you look, you are always looking through the optic zone resulting in perfect vision. Also, contact lenses are less likely to receive scratches or break as easily as glasses are and they are immune to fogging and will give clear vision even on a rainy day.

There are basically two kinds of contact lenses; Soft contact lenses and RGP (rigid gas permeable) contact lenses. Both of these types of contact lenses can be used to correct all kinds of vision. For example, myopia, hyperopia, astigmatism and presbyopia. Soft lenses are easier to wear and more comfortable while using initially, that's the main reason why they are chosen by more than 80% of contact wearers. RGP lenses are used only when you need to wear them continuously over a long periods of time.

Choosing a contact lens depends upon the results of your optical examination by your ophthalmologist. It is always smart to inform him that you wish to use contact lenses and not glasses, so that the ophthalmologist can test your eyes accordingly and make the time to fit your contact lenses correctly. This might be against your ophthalmologist’s preferences, as some of them do not recommend contact lenses unless you ask them specifically for a set.

Sports persons, riders, acrobats etc, are some of the people best suited for contact lenses because it doesn't interfere with their professional lives. But that doesn't mean you shouldn't wear them because your not in a highly physical active profession. If you would feel more comfortable wearing contact lenses instead of glasses all the time by all means talk to your doctor and try them. Contact lenses can correct all kinds of visions and are very suitable for most people that wear glasses but before you make that decision it is imperative that you talk to your ophthalmologist first.
