A condition of the eye where light does not focus evenly on the retina, causing blurred or distorted vision.
She was diagnosed with astigmia and needed glasses to correct her vision.
Astigmia is derived from the Greek roots 'a-' (meaning without) and 'stigma' (meaning point or mark). The term refers to a condition where the eye does not focus light evenly onto the retina, resulting in blurred vision, hence 'without a clear point of focus.'
Think of 'without' ('a-') and 'point' ('stigma') to remember that astigmia means a lack of a clear point of focus in vision.
