(Charts that have been converted to metric measurements show normal vision to be 6/6. This indicates that the line marked “6” can be read from a distance of 6m.) A person with 20/100 can only read line “100” from 20ft., which is very poor vision. A person with 20/15 vision has better than 20/20 vision. Stand 20 ft. from the eye chart. ................
