The optical condition or state of having emmetropia; normal, uncorrected vision.
From 'emmetropia' plus the suffix '-ism' (a state, condition, or practice). This noun form emphasizes the condition itself.
The '-ism' suffix usually describes beliefs or conditions, so 'emmetropism' treats perfect vision as a state of being rather than just an absence of problems.
