- Visual Field: A someone's optical field (the totality area realise when looking straight before without moving the eye) is narrow to 20 degrees or less in the better eye. This is much referred to as "tunnel vision".
The term "best-corrected" is important. It means that still when wear the strongest potential eyeglass or contact lens, the mortal still falls within these parameter. If sight can be improved beyond 20/200 with glasses, the individual is loosely not classified as lawfully blind.
