It may not be convenient, or cost-effective, to have every pre-Kindergarten or Third grade child travel to a special clinic for the recommended Patched, Surround Optotype Acuity Screening. Therefore, ABCD has developed a downloadable kit which can be used by parents, teachers, public health nurses or aids, pediatricians, etc. The "kit" consists of a surround HOTV chart for use at ten feet from the child with 20/40 cut-off for Kindergarten and 20/32 cut-off for Third Graders. The kit also sends a Matching Card with Instructions. Parents can generate effective patches from readily available duct or masking tape. A PinHole card can also be made to allow children with mild glasses problems to defer their confirmatory exam.
