eyesight
Ability to see
Eyesight is the ability to see—the faculty of vision.
Good eyesight means clear, unimpaired vision; poor eyesight requires correction with glasses or contacts.
His eyesight began to fail in his seventies.
The word emphasizes the physical capacity rather than the act of looking or perceiving.
