Section 67-1105 - Loss of Vision

A. Loss of vision is based on reading without the use of corrective lenses. Eighty percent loss of vision, or more, is considered one hundred percent industrial blindness.

B. The following table, derived from the Snellen Notation, is used to determine the percentage of impairment to vision. The physician also may rely upon the American Medical Association's "Guide to the Evaluation of Permanent Impairment" and any other accepted medical authority or treatise in deriving an impairment rating.

C. Loss in muscle function, in conjunction with other factors, may warrant a greater percentage of loss of vision.
