The best way to keep your eyes healthy is to work closely with an optometrist and have annual comprehensive eye examinations. These will help detect any eye abnormalities and diseases before they become serious. Our Tampa eye doctor not only can detect potentially serious problems with your eyes but also will diagnose and offer correction for any problems with your visual acuity.
One problem that affects visual acuity is astigmatism. Astigmatism is a disorder of the shape of the eye. Normally the human eye is spherical in shape and when light enters the eye it refracts evenly creating a clear view of the object. With astigmatism the eye is shaped more like a football or the back of a spoon. When light enters an eye with astigmatism it is refracted more to one direction than the other, which allows only part of the object to be in focus making objects appear blurry. Astigmatism can be present at birth or be caused later by pressure on the cornea from the eyelids, incorrect posture or increased use of the eyes for close work. Symptoms of astigmatism include blurry vision and often headaches, eyestrain and fatigue. Astigmatism is diagnosed through an exam in our office the malady often accompanies nearsightedness or farsightedness. It may also worsen as you get older so have your eyes checked by our Tampa eye doctor whenever you feel there has been a change in your vision.
Our Tampa eye doctor treats astigmatism primarily through the use of prescription corrective lenses either in eyeglasses or contact lenses. Mild astigmatism may not need any treatment at all, but since astigmatism often accompanies nearsightedness or farsightedness corrective lenses will take care of both conditions. Special toric lenses that have greater light bending power in one direction than the other are used in glasses or contact lenses for people with astigmatism. Another means of treating astigmatism is refractive or laser surgery, where the shape of the cornea is changed to make it more spherical. Your eyes have to be otherwise healthy for refractive surgery to be used. If you have any of the symptoms of astigmatism or you feel that your vision has changed lately call our office for an appointment to rule out astigmatism as the cause.
