What does "corrected vision" mean?

Corrected vision refers to the level of visual acuity achieved after correcting refractive errors (such as myopia, hyperopia, astigmatism, etc.) in the eye through methods like wearing glasses or undergoing surgery. If unaided visual acuity is below normal levels, optical correction methods can improve visual clarity, enabling clear vision of objects at a distance or up close. This is the process of vision correction. During an examination, doctors typically assess a patient's corrected visual acuity to evaluate the overall health of their eyes. If the corrected vision is normal, it indicates there is no obvious organic eye disease present. However, if corrected vision is reduced, it may indicate the presence of certain eye conditions such as cataracts, iridocyclitis, or macular degeneration, which would require further investigation and treatment.
