What Does the Screening Test Evaluate?
Visual acuity screening tests evaluate how well the child sees
small objects far away.
What You Need to Do the Test:
1. Two crowded Single Lea Symbols Visual Acuity test cards
(Disk cards). One card is for 3-year-olds and one card is
for 4- and 5-year-olds. At each age level, one side is for
testing the right eye and one side is for testing the left
eye so children don’t memorize the order of symbols. The
masking window displays one symbol at a time. The wheel
rotates from one symbol to the next. Each side of each card
contains 8 symbols (combinations of an apple, house, circle
and square) surrounded by crowding bars (lines around
each symbol).
2. Lap card which displays each of the 4 symbols (with
crowding bars).
3. Single, large symbols (one each of the apple, house, circle
and square) with crowding bars for pre-testing.
4. Baseline flip book for testing the right eye and left eye at 5
feet.
5. Two pair of occluder glasses (one for testing the right eye
and one for testing the left eye). Micropore tape or junior
size eye patches (e.g. Opticlude patches).
6. VIP illuminator with power supply and measuring cord.
7. Tissues to wipe the ear pieces and nose area of the
occluder glasses.
8. Antibacterial wipes to clean the lap card.
9. A sturdy table or chair to set the lamp stand on.
10. Chairs for the child and the screener.
11. Recording form and pen.
12. A small hand-held mirror (optional)
Getting Ready:
1. Place the lamp stand on a table or chair and turn the lamp
on.
2. Select the disk card and recording form
that are appropriate for the age of the
child to be tested.
3. Slide the disk card for the child’s age
into the slot on the lamp (right eye side
towards the child). (Assure that no
symbol is visible through the window.)
4. Use the measuring cord to position the
child’s chair so that the card is 5 feet
from the child’s eyes. Place one end
of the measuring cord in the notch on
the lower right side of the lamp stand (see right). The other
end of the cord marks the position of the child’s eyes. The
child should be looking straight ahead at the cards and the
cards should be at the same level/height as the child’s eyes.
If possible, mark this spot on the wall or floor with tape to
facilitate monitoring test distance during testing.
5. Record the screener’s name and child’s name and age
on the form.
