Legal blindness relates to the best corrected vision after an eyeglass prescription is determined. You cannot look at the numbers on your eyeglass prescription to determine this. If the best you can do on an eye chart, with the best eyeglass correction, is 20/200, that is legal blindness in most states in the usa.
Legal blindness is a term used to establish eligibility for Social Security and other benefits. The next largest letters on most eye charts (2200) is the usual standard. These letters are 10 times larger than 20/20; this refers to best corrected vision only. No permanent damage is done to adults who wear an incorrect eyeglass or contact lens prescription. You may, however, be uncomfortable wearing them and annoyed by the inconvenience.
