Color plates: Your pcp may have a copy of the ishihara (?Sp) plates that are used as a screening test for the various levels of color blindness. I seldom have a request for this screening but find the process helpful. My pcp found a mild issue with my vision with my pre college exam & i keep a copy of the book around to screen kids if asked. If he is old enough to answer questions this can pick it up.
