Legally blind means eligible for compensation as if blind, not being actually unable to see. GURPS bad sight is quite severe, it arguably reaches the definition of legally blind.

In terms of actual effects, at a range of 1 yard, 20:20 vision has a resolution of 0.01" (about 1 pixel on a typical monitor). Having a resolution of merely 0.1" will not especially affect anything most animals care about, though for animals with binocular vision it does affect parallax detection (range uncertainty of a couple inches at a range of 1 yard).
