ASTIGMATISM
EYE HEALTHCARE – ASTIGMATISM
For someone with a substantial level of astigmatism, it means that objects at some orientations will be more defined and in focus than objects at different orientations. The overall effect is a general blur to the individual, depending on their level of defect.
Although astigmatism can develop from eye injury, surgery or eye disease, almost all cases exist from birth. Its direct cause is not well understood, though there is a strong genetic link and correction is required early in life to prevent astigmatic Amblyopia (lazy eye).
