How Do Eye Contacts Work?

0

Contact lenses are prescribed to a wide variety of individuals who have vision problems associated with astigmatism, nearsightedness, farsightedness, and presbyopia. The retinas of individuals who suffer from these conditions cannot properly focus light. When the retina does not function properly and/or does not properly focus light then the result is imperfect and blurry vision. Contact lenses are made differently depending on the eye condition they are trying to correct. For instance, if you suffer from astigmatism your optometrist will measure your cornea so a contact can be made precisely to fit your eye. By doing this a contact is made that will fit your eye perfectly and direct light rays to one place on the cornea, which in turn corrects your vision. Those suffering from myopia, also known as nearsightedness, will wear lenses that are thinner in the middle and thicker on the edges. This design allows the light rays to be processed correctly by the retina. Farsightedness sufferer
