The refractive errors of the eye results in nearsightedness, farsightedness, and astigmatism. Nearsightedness (also called myopia) is a condition in which the far off objects and images do not appear clear while the objects placed near could be seen clearly, while patients with Farsightedness (also called Hyperopia) face problems in seeing closely placed objects clearly. Farsightedness and Nearsightedness both can occur simultaneously too. Astigmatism is another kind of refractive error which occurs in aged persons. The patient loses the ability to focus on near or close objects.
Shortsightedness can also be caused due to cataracts.
These vision problems can be corrected by using contact lenses. Different type of contact lenses are recommended for each of these medical problems.
The wide varieties of contact lenses have made us able to choose the one which suits our lifestyle the best. Contact lenses are made to place directly on the eye cornea where it floats on thin layer of tears. The newer contact lenses are thinner, softer, and easier to be placed on the eye cornea.
