Low vision is defined as what?

• A. Residual vision
• B. Snellen eye chart
• C. Phoric
• D. eyesight that cannot be corrected with eyeglasses, contact lenses, drugs, or surgery

Answer: (D)

Low vision describes a level of sight that remains impaired after trying standard corrections. This means even with proper eyeglasses, contact lenses, medications, or surgery, the vision can’t be brought back to normal, yet the person still has usable sight. That residual impairment affects everyday tasks and often calls for adaptive tools and strategies to help function more effectively. The statement that eyesight cannot be corrected with common corrective methods captures this idea directly. The other options aren’t definitions of low vision: residual vision is just the remaining sight, a Snellen chart is a measurement tool, and phoric relates to eye alignment, not a definition of vision level.
