What is the term for normal vision?

Explanation:
Normal vision in eye health terminology is emmetropia. This means the eye’s optical power and its length are matched so light from distant objects is focused directly on the retina without needing glasses or lenses. When this balance is off, different refractive conditions occur: hyperopia is when the focal point sits behind the retina, making near objects blurry; myopia is when the focal point falls in front of the retina, blurring distant objects; presbyopia is age-related loss of the ability to focus on close objects. Emmetropia represents that no refractive error is present, giving clear distance vision without correction.
