Visual acuity test using four letters (H, O, T, V) designed for preschool children.
Full Definition
HOTV is a visual acuity testing method specifically designed for preschool children aged 3-5 years who may not yet know the full alphabet. The test uses only four letters - H, O, T, and V - which are presented at various sizes and distances. Children can respond by naming the letters, pointing to matching letters on a response card, or using other age-appropriate methods. This test provides more reliable visual acuity measurements in young children compared to picture charts and helps detect amblyopia and refractive errors early in development.
Usage
Usage note: Ideal for children who know some letters but cannot read full words yet.
