Contact lenses, also called soft contact lenses, are small, thin lenses usually placed directly on the cornea of the eyes. Contact lenses are tiny ocular prosthetics worn by more than 150 million Americans worldwide, and they are often worn for corrective vision, either for aesthetic or therapeutic reasons or for reasons that have nothing to do with improving vision. Contact lenses come in two different varieties, the water-resistant kind and the water-filled variety. While some people wear their contacts for all purposes, others only wear them for a specific purpose, like correct vision.
There are two types of contact lenses, soft and rigid. Rigid is the most common variety, as its name implies. Rigid contact lenses require that you clean them at least once a week in order to maintain their effectiveness, which means that you need to go to an eye care professional at least once a month to have them cleaned. Soft contact lenses require no cleaning, although they may need to be spot-cleaned with some mild soapy solution at certain times of the year. If you choose rigid lenses, then you should know that you need to return them to the store where you purchased them after you have used them for six months or more. In the event that your contact lenses lose their effectiveness after this time, it is necessary to purchase another pair.
There are many advantages associated with rigid gas permeable (RGP) contact lenses, which provide a clear, smooth surface to rest on. RGP contact lenses do not rub against the eye, which eliminates the potential for eye irritation and even pain. Also, RGP contact lenses do not retain debris, which means that they are less likely to be contaminated. This also eliminates possible bacteria build-up. The contact lens is also less likely to get dirty or dusty, which can also potentially cause eye irritation.
But in addition to all of these benefits, there are some disadvantages to consider as well. First, you need to realize that even though RGP contact lenses are easier to remove, you still need to follow proper care and maintenance in order to ensure that your eyes remain healthy. Because of the way that RGP is designed, it is very easy for particles to get trapped between the lens and the cornea; this can lead to issues with vision if proper care and maintenance are not used. Even if you follow proper care and maintenance, it is still possible for some RGP contact lenses to come out of your eye at the wrong time, such as when you try to sleep. If this happens, you will need to consult an eye doctor in order to have your eyes tested for any vision problems.
In order to avoid these complications, you should take care and proper care when putting on and taking off your contact lenses. It is important to wash your hands thoroughly before you put on your contacts so that your hands will be free of germs. Then you should put them in a clean eye sleeve or case; this will allow you to properly insert your contact lenses without contaminating your eyes. When you remove your contact lenses, you should always use a clean, moistened finger; this is done in order to prevent bacteria from forming in your fingers, which can worsen your eye infections.
When you wear contact lenses, you will need to visit an eye doctor at least once a year to have your eyes checked. Your eye doctor will be able to examine your eyes properly in order to make sure that your eyes are healthy and that your contact lenses are working properly. He or she may also perform a comprehensive visual examination to determine which medical devices are needed by you in order to maintain the health and appearance of your eyes. Although you may think that your eyes are fine, you may never know how long you could suffer from eye problems if you do not take care of them properly.
