For a 2004 bilateral loss of vision that becomes permanent and stationary, how is the disability rated?

• A. Ratings are based on vision with best practicable correction
• B. Whichever eye rates highest is used
• C. Ratings are based on uncorrected vision
• D. The standard rating is based on disability found under reduction of vision plus half the difference

Answer: (A)

Disability ratings for permanent bilateral vision loss are determined from vision with best practicable correction. This means you assess how the person would function with the best corrective options realistically available (glasses, contact lenses, surgery, etc.) rather than judging from uncorrected vision or from one eye’s acuity alone. By using the best possible correction, the rating reflects the true residual impairment after optimal correction, which is important when both eyes are involved.

This approach differs from judging uncorrected vision, which could undervalue impairment, and from methods that use only the higher eye or apply a “reduction of vision plus half the difference” formula, which are not appropriate for a bilateral, permanent, stationary loss.
