Tell the child to keep both eyes open and read or match (if using HOTV matching cards) the critical line of letters with the uncovered eye. Observe the child and make sure he or she is not peeking, squinting or tilting their head.
- Page 6 7 HOTV Matching Card (20/80 size from 10 Ft) HOTV matching cards can be used by children unable to identify their letters to help them perform the test. We recommend laminating the cards and disinfecting them after each use, or consider them as one-time use material.
