Common Vision Conditions: Astigmatism
Astigmatism is a seemingly exotic word and often humorously mispronounced. It is a common vision condition in which light entering the eye can’t be focused clearly – in fact over 90% of all patients we see have some degree of astigmatism. Astigmatism is also often described as the front surface of the eye (cornea) being football shaped, egg shaped, or a warped camera lens. The “nerdy” definition is that an image will come to focus in two different meridians either before or after the retina, thus it is associated with nearsightedness and farsightedness, which is obviously why we don’t describe it this way to our patients.
