Diseases contact lenses can cure
There are several diseases contact lenses can cure. These diseases include nearsightedness, farsightedness, and astigmatism. In addition, soft lenses are sometimes prescribed after cataract surgery to help with vision correction. With all the options available to purchasers, there is little reason not to use these lenses for diseases contact lenses can cure.
Myopia, or nearsightedness means that people can only see what is close, or near to them. Hyperopia, or farsightedness means that people cannot see what is close to them, i.e., the need for reading glasses. Astigmatism is when the eyes do not focus correctly. In astigmatism, the images seen by the eye are not focused on the retina correctly resulting in the brain not receiving the image properly.
Other diseases contact lenses can cure involve diseases of the cornea, conjunctiva, or lids. In addition, contact lenses provide unique help for those suffering from keratoconus.
Keratoconus is a disease of the eye wherein the cornea starts to thin out and form into bulge, much like a cone. As the disease progresses, the cornea gets droopier and droopier causing the individual's vision to become blurry. Regular glasses cannot help individuals with keratoconus. However, because contact lenses sit right on the eye, they correct the individual's vision problem at their source.
In addition to the above listed diseases cured by contact lenses, contact lenses can also cure presbyopia, or the need for bifocals. Contact lenses prescribed for presbyopia have two vision powers on the same lens, one for seeing things close up and one for seeing things that are farther away. It is an ideal alternative for individuals needing bifocal glasses.
