Abstract

To the Editor.—  The Denver Development Screening Test has elevated the humble raisin to prominence in establishing the visual development of an infant and his eye-hand coordination. The raisin is attractive to most small children but the fact that a child can see and pick up a raisin does not mean that he has normal vision.We recently "calibrated" a raisin to determine just how much vision a child needs in order to see one and pick it up. We were surprised to find that, presented on a neutral gray background at a distance of 14 inches, it requires only 20/2,000 vision to see a raisin well enough to find it.We would like to recommend to all pediatricians and those interested in the development of children that the ability of a child to find and grasp a raisin does not, therefore, indicate that he has normal vision.
