Common Eye Vision Conditions

Besides refractive errors that necessitate vision correction, there are a few common eye conditions that people can have. They are astigmatism, glaucoma, myopia, hyperopia and presbyopia.


Astigmatism:
condition in which the cornea's curvature is asymmetrical - sometimes, this is described as the eye being shaped more like a football than a baseball. The eye is therefore unable to focus clearly. This can be corrected with toric contact lenses
Glaucoma:condition in which the pressure inside the eye is elevated because of excessive amounts of fluid (aqueous humor). This can damage the optic nerve and cause a range of impairment, from loss of peripheral vision, or blindness. Chronic glaucoma usually begins in people over the age of 40
Myopia:also called nearsightedness. People with this condition can see clearly up close but not at a distance
Hyperopia:also called farsightedness. People with this condition can see clearly at a distance but not up close
Presbyopia:condition that usually affects people 40 and over. People with usually normal vision find it more and more difficult to read and do detailed work unless they're very close up. People with presbyopia can find help in the use of reading glasses, or bifocal or multifocal contact lenses
