The crowded Near Test Card is perfect for measuring the near vision of pre-literate children and adults with a learning disability. The pictures are sized for 33cm testing distance and measure from 0.8 to -0.1 LogMAR ( 6/38 to 6/4.8 Snellen). The card is double sided and matt-laminated. On each side is both single and linear crowded pictures in crowding boxes so that children from around 18 months of age upwards can be tested. Each side has a different arrangement of the picture optotypes to test each eye separately.
