Medical Definition of Sand-blind
Sand-blind: Partly blind, semi-blind, half-blind. From the Old English samblind from sam- meaning semi- + blind. In the erroneous belief that the term referred to blindness caused by sand, Samuel Johnson defined the term in his great Dictionary of the English Language (1755) as: "Having a defect in the eyes, by which small particles appear to fly before them."
