Contact lens, also known as toric contact lenses, are thin lenses usually placed directly on your eyes. Contact lenses are extraordinary ocular prosthetics used by more than 150 million individuals worldwide, and they are worn to correct certain vision problems or for therapeutic or cosmetic reasons. One thing that is very interesting about contact lenses is that they do not have a need for glasses to get prescribed. In fact, they are the only corrective device that does not need to be prescription lenses because they are placed directly on your eye’s surface.
There are several important facts that you must know about contact lenses. First, they are one of the safest and most effective means to achieve your vision correction goals. Second, your eye doctor should instruct you to never reuse your contacts because it increases the risk of infections. And third, although they are a perfect substitute for eyeglasses, your eye doctor may suggest that you wear eyeglasses in order to prevent infections from occurring in your contact lenses.
You may also be wondering how they actually work. The fact is that contact lenses are made from a solution called a solution and a binder. The purpose of this is to seal the contact lens to the cornea and to form a tight seal. Once this is done, you would be able to make longer and even stronger connections to your eye’s cornea with your artificial eye. The problem however is that some individuals experience problems with their eyes getting dry because the binder cannot totally close.
In addition to the moisture, the soft contact lenses may also cause corneal abrasions and might result to some discomfort or irritation. This is why it is recommended that you use disposable or extended wear contact lenses. Although disposable and extended wear lenses may be more expensive, the advantage they have is that you can just throw them away after you wear them. However, the disadvantage they have is that it is easy to develop eye infections with soft contact lenses because they lack the barrier of the cornea.
There are also some advantages and disadvantages when it comes to wearing contacts. One advantage is that contacts can give you an entirely new look. Since contacts are available in different colors and patterns, it can help you customize your appearance. On the other hand, extended-wear lenses can be used for two years or more, which is a huge advantage compared to regular glasses that may only last for a year or two.
Aside from wearing contact lenses, you may also opt to get laser eye surgery to treat your vision. But there are some risks involved with this. One of them is that you may experience very intense pain due to the presence of a high beam of light. Another is that the results of this procedure may take longer than anticipated. So it is highly recommended to talk to your doctor first before deciding whether you should undergo eye surgery or not.
