What is astigmatism?
Astigmatism occurs when your eye is not entirely round. In truth, astigmatism is present in almost everyone – but it only leads to blurry vision at a certain degree.
Think of your eye as a spherical ball. Usually, when light enters your eye it bends evenly. This creates a sharp image of what you see on the tissues at the back of your inner eye. However, if you have astigmatism your eye is shaped more like an elliptical football. As a result, the light is not bent evenly and only one part of the picture is transmitted clearly and in focus at one time.

What is a stigma?
Stigma is actually referring to a type of refractive error known properly as astigmatism and it's is relatively common. There are three types of refractive error, myopia, hyperopia, and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts.
Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in-depth fitting procedure.
Sometimes, this symptom is blamed mistakenly on eye fatigue or strain. But only a complete eye exam in Johnson City can determine the problem; contact our eye doctor to book an appointment.
