The best alternative to glasses is contact lenses, as most people know. Contacts are small, plastic discs, which are usually used for correction such vision problems as nearsightedness, astigmatism, farsightedness, and others. Besides very often people who had a cataract surgery wear contact lenses, in this case lenses help your eye to heal a little bit faster. Please remember: before wearing any contact lenses you must visit your eye care doctor to make sure that you can wear contacts. Besides your ophthalmologist will help you to fit the lenses you need, especially if you are going to wear contacts with a purpose of vision correction. One more reason to visit your doctor is that only with professinal help it is possibleto choose the contact lenses which will suit you perfectly and your wearing will be comfortable and safe. Contacts are put in the eye, where they cover the puil of your eye. There are two main types of contact lenses - hard and soft contact lenses. The hard contact lenses are divided into gas permeable and the conventional hard lenses. Soft contact lenses are devided into daily wear, extended wear, and disposable wear. Of course, all these contact lenses are good enough in using, but you should check with your ophthalmologist any way to know what type is recommended for you.
In case you have just begun to wear contact lenses or only think about this you will need some time to adjust to them. Hard contact lenses will take you from two to four weeks period for adjusting: every day you will wear your contacts longer and longer. Soft contact lenses usually take less time for adjusting and most people need only a few days for this process.
A lot of many specific uses of contact lenses are well known today. Except the usual vision correction, contact lenses can also be used to treat some eye disorders like cataracts, in case the natural lens around is absent or injured. Contact lenses can be used also for the tretment and cure of different eye diseases and scars on the cornea. Contact lenses can solve a lot of problems, especially they help a lot those people who lead active life, for example athletes. When you are running they don’t slide off your nose like eye glasses, besides they don’t fog up and as they are weightless you usually don’t feel them in your eyes. One more advantage of contacts is that they widen your field of vision, this is very convenient if you are going in for sports. The principle of working of the lens is the same as glass, this means that you will get the same vision from contacts as if you wear eyeglasses. Many people who have some vision disorders tend to think that getting Lasik eye surgery for curing their vision will help to avoid wearing contact lenses at all. In fact there are some risks connecting with this procedure: at first this way of treatment is very expensive, secondly it can provoce some problems with your eye vision in future. In this case contact lenses are much cheaper than Lasic treatment and besides they are a safe alternative to vision correction.
