It's a common condition that can be diagnosed during an eye exam and can be corrected with glasses, contact lenses, or surgery.

Etymology
The term 'astigmatic' originates from the Greek word 'a-' meaning 'without' and 'stigma' meaning 'point' or 'mark'. The word initially referred to the absence of a point focus of light due to the irregular shape of the cornea or lens. First introduced in the early 19th century, it has since been used in the field of optometry to describe conditions affecting the clarity of vision. The understanding of astigmatism has evolved alongside advances in optics and eye care, and it has become a standard consideration in eye examinations and corrective procedures.
