My kid has never had an eye examine and I'm wondering if I should take her. She's 3 and a half and as far as we've noticed, she can see very well, however BD and his family all have really really bad eye sight and my sister and my parents wear glasses. Does she need one? If so, who do I take her to? Can she go to like... one of the places in the mall, Lens Crafters, Sears Optical, etc or does she need to go to a special place?
