What visual acuity defines low vision?

• A. Worse than 20/400 in the better eye
• B. 20/200 to 20/60 in the better eye with correction
• C. Worse than 20/100 with correction
• D. 20/30 or better in the better eye

Answer: (B)

The definition of low vision is characterized by visual acuity that ranges from 20/200 to 20/60 in the better eye when corrected. This range indicates that the individual may have difficulty performing everyday tasks, even with corrective lenses, and requires specialized services or aids to enhance their visual function. This classification of low vision recognizes that individuals in this range may benefit from various interventions, including occupational therapy, to help them adapt to their environment and maintain independence. For instance, they might use magnifying devices, strategic adaptations within their living spaces, or specialized training to optimize their remaining visual function. Definitions for visual acuity levels below or above this specific range pertain to other classifications, such as severe visual impairment or normal vision. Those with worse acuities, such as worse than 20/400, fall into more severe categories of visual impairment, while those who can see 20/30 or better are generally considered to have normal vision and do not fit within the low vision category.
