Morphology

astigmatism = stigmatism (opaque) = a + stigmat + ism

The prefix 'a-' negates 'stigmatism', but the medical meaning is not transparent from the base word.

Etymology

The word astigmatism comes from Greek parts a- meaning 'not' and stigma meaning 'point'. So it means 'no point', which helps you remember that light does not focus to one point in the eye and vision becomes blurred.
