not having astigmatism
Etymology
'nonastigmatic' originates from the English combination of the prefix 'non-' (from Latin 'non', where 'non' meant 'not') and 'astigmatic' (ultimately from Greek elements), where the prefix 'non-' meant 'not' and the Greek root related to 'stigma' meant 'mark' or 'point'.
'nonastigmatic' developed in modern English by attaching the productive negative prefix 'non-' to 'astigmatic'. 'Astigmatic' itself was borrowed via Modern Latin/French from Greek (Greek 'astigmatikos' from 'a-' + 'stigma'), and then formed in English as 'astigmatic'; adding 'non-' produced the compound 'nonastigmatic'.
Initially the component roots concerned the idea of a 'point' or 'mark' (stigma) and, in optics, whether a point is formed; over time 'astigmatic' came to mean 'having astigmatism', so 'nonastigmatic' now straightforwardly means 'not having astigmatism'.
