What is visual acuity?
What is it called when someone has compromised far acuity?
What is it called when someone has compromised near acuity?

Visual acuity (VA) commonly refers to the clarity of vision, but technically rates a person's ability to recognize small details with precision. Visual acuity depends on optical and neural factors. Optical factors of the eye influence the sharpness of an image on its retina. Neural factors include the health and functioning of the retina, of the neural pathways to the brain, and of the interpretative faculty of the brain.[1]

The most commonly referred-to visual acuity is distance acuity or far acuity (e.g., "20/20 vision"), which describes someone's ability to recognize small details at a far distance. This ability is compromised in people with myopia, also known as short-sightedness or near-sightedness. Another visual acuity is near acuity, which describes someone’s ability to recognize small details at a near distance. This ability is compromised in people with hyperopia, also known as long-sightedness or far-sightedness.

drishy tikshnata kii ek choti paribhaasha kisi ko chote, sateek vivaran ko notice karne kii kshamta he.

koi vyakti jisane dur kii tikshnata se samjhauta kiya he, vah adoordarshee yaa nikat-drushti vaala he, jise chikitsakeey rup se myopia ke rup main janaa jaataa he.

koi vyakti jo tikshnata ke paas samjhauta kar chukaa he, vah lambey samay se dekhe jane vaala yaa dur-dur tak he, jise chikitsakeey rup se hiparopia ke rup main janaa jaataa he.
