As most of us know, contact lenses are the best alternative to glasses.They are small, plastic shaped discs that are made to correct eyesight problems like nearsightedness, astigmatism, farsightedness, and other problems. Contact lenses are also used by those who have had cataract surgery, as they can help the eyes to heal a bit faster.
Contacts are used in the eye, where they will float above a sea of tears that rest in front of the cornea. You should always go to a doctor to be fitted, as the proper fitting and design is very important for safety, comfort, and the accurate vision. If you don’t get fitted for your contacts, you could very well get a pair of contacts that could damage your eyes.
There are several types of contact lens available in two main types – hard contact lenses and soft contact lenses.The hard contact lenses include gas permeable and the conventional hard lenses. Soft contact lenses include daily wear, extended wear, and disposable wear. These are all great contacts, although you should check with your optician to see what he recommends.
If you are just starting to wear hard contact lenses or have thought about them in the past, you'll need a 2 - 4 week break period, where you will gradually wear the contacts longer and longer with each passing day. Soft contacts on the other hand, will take less time to get used to, as most people who wear them can break them in a few days.
Contact lens, as we all know, have many different uses. They are mainly used to correct vision, although they can also be used for those who have just had cataracts, especially if the natural lens around was removed. Contacts can also be used in the treatment of various eye diseases, and scars on the cornea that have been caused by infections or injury.
