In 1508 Leonardo da Vinci described and drew the sketch to express his idea of a contact lens. But it was Sir John Herschel, a British astronomer in 1827, who stunned the world with his idea, a form of the human eye, so that a lens could be made to fit perfectly. And later in the year 1887, sixty years, used to create FA Muller, a German glassblower these ideas to the world's first known contact lenses.
Contact lenses are in full-contact opticalAccessories, the other directly on the cornea are simply better and more natural vision as a contemporary glass. Distortions caused by side vision and eye lens distance is invalid when dealing with contact lenses. With the glasses from the eye lens is the size of the objects appear larger or smaller than actual depending on whether you are far sighted or near sighted.
One problem with the glasses is that peripheral vision due to the frame block. If you are looking sidewaysup or down, find out the size of the lens, which makes one object without the glasses look what's in distorted or blurred, because you are not looking through the optical zone.
This is all the more so because of the smaller frame in the style of today. Well, if you wear contact lenses, no matter which direction you look, you're always looking through the optical zone allowing a perfect view. In addition, contact lenses are lesslikely to get scratched or break as easily as glasses and they are immune to the fogging and provide clear vision even on a rainy day.
There are basically two types of contact lenses, soft contact lenses and RGP (rigid gas permeable contact lenses). Both types of contact lenses can be used for all types of vision. For example, nearsightedness, farsightedness, astigmatism and presbyopia. Soft lenses arecomfortable to wear and comfortable while you are first, that the main reason why they are chosen by more than 80% of contact lens wearers have. RGP lenses are used only when you need them to be worn continuously for a long period of time.
The choice of a contact lens depends on the results of your visual examination by your ophthalmologist. It is always wise to inform him that you want, do not use contact lenses and glasses, so that the ophthalmologist canTest your eyes, and therefore the time to properly fit your contact lenses. This could be against the preferences of your eye doctor, because some of these lenses is not recommended if you ask them specifically for a series.
Athletes, riders, acrobats, etc. are some of the people best suited for contact lenses, because they do not interfere with their professional lives. But that does not mean you should not wear it because yournot in a very physically active job. If you would feel comfortable wearing contact lenses instead of glasses all the time by all means talk to your doctor and try this. All types of contact lenses can correct vision and are very suitable for most people who wear glasses, But before you make that decision, it is imperative that you inform your eye doctor first conversation.
