Although sometimes uncontrollable, vision problem is perhaps one of the last things you want to deal with while alive. However, the good news is that colored contact lens technology can dramatically change the life of a person with vision problems and improve the quality of his or her life. Vision correction is a global problem and surveys suggest that approximately 170 million people in the U.S. use some corrective devices whether they are contact lenses or eyeglasses. This is more than half of America’s population, right? With the growing number of cases involving vision impairment, many people are now turning to contact lenses to help correct or improve their vision. As a result, the number of people wearing contact lenses continues to grow by more than 4 percent annually since 1991, statistics indicate.

How Do Contact Lenses Help?

As the name suggests, contact lenses are small prescription lenses that come in contact with the eyes and meant to correct refractive errors. They are also designed to maintain an individual’s ocular health. Ordinarily, they float on the tear film layer around the cornea. They are designed to work the same way eyes function—to refract and focus light to enable objects to appear as clearly as possible. These lenses move naturally with the eyes since they are installed on the tear fluid of the eye surface. Therefore, it is not easy for someone wearing contact lenses to be noticed, which is an advantage over the ordinary eyeglasses.

Types of contact lenses

Not all contact lenses are the same. They come in different designs and forms suited for different needs. For instance, you can find lenses for short or nearsightedness or those meant for astigmatism, and more. In addition, these contact lenses come in different performance strengths. You can work with your doctor to choose the right prescription for your specific condition. These contact lenses feature plus or minus signs and then with some figures. These components on the description tell more about the shape of the lenses. Remember different shapes are meant to correct specific vision problems.

Colored contact lenses

Perhaps you wish or have seen people whose eyes seem bluer than they naturally should, right? You can also wear contact lenses for cosmetic reasons if you do not have a vision defect. Cosmetic lenses thus change the look of your eyes without introducing any magnification. If you are looking to complement your Halloween look, you can find black sclera, zero power lenses. However, it is important to seek the advice of an eye expert before you wear them since they are purely prescription devices. No matter what your vision or cosmetic requirements might be, the market has a range of colored contact lens that will fulfill your needs.
