Contact lens, or just simply contact lenses, are thin rigid lenses usually placed directly on the eye’s surface. Contact lenses are great ocular prosthetics used by more than 150 million people around the globe, and they are worn for aesthetic or corrective reasons or for medical purposes. Contact lenses have been a huge trend in the world of eye care and are really taking off nowadays. They provide an easy way to get a perfect vision all the time.
People who wear contact lenses experience many advantages, which is why they are increasingly becoming the preferred choice for vision correction. The most obvious advantage of contact lenses is that they are comfortable to wear. Unlike glasses, wearing contact lenses does not cause any discomfort to the wearer. Wearing glasses for an extended period of time can cause eye strain and irritation to the eye, as well as frequent eye scratches and bumps on the face. Moreover, contact lenses are often more affordable compared to glasses.
Another advantage of wearing contact lens is that they are available in different prescription strengths. The weaker the prescription, the lower the cost and the easier it is to buy contact lens. As a result, even people with mild astigmatism can wear contact lens for an extended period of time without any hassle. Astigmatism is the result of a slightly irregularly shaped cornea and contact lens provide a great solution to this eye problem.
One of the biggest disadvantages of contact lenses is the risk of infections. Some of these risks include inflammation of the eye, allergic reactions, infections and cases where the cornea gets cracked. However, these risks are very rare and it is the result of a person using a contact lens with an incorrect fit. In this case, contact lenses must be corrected immediately so the cornea can regain its shape. If the problem is allowed to continue, the cornea may get even worse and the patient may need corneal surgery in order to correct the problem.
Wearing contact lenses has some advantages. Most people who wear them say that they feel more comfortable than their usual glasses or contact lenses. In addition, they offer better vision. However, if these advantages do not convince you to stop using your contact lenses, then you might be afraid of having bad vision. Contact lenses must not be used for outdoor purposes and while playing sports, as these activities can lead to dry eyes, inflammation, infections and other problems.
In general, the contact lens is a popular choice among many people. However, before using contact lens make sure you consult with your eye doctor. This is important to avoid unnecessary risks, such as an eye infection, irritation, corneal cracks, etc. Make sure that the contact lens is comfortable and appropriate for your eyes. If you wear contact lenses for a long time, it is important to change them regularly, even when your prescription suggests that you can wear them continuously for several years.
