LEA Grating Paddles

For infants, visual acuity is measured with grating acuity tests. This is a detection test for preferential looking situations. The handle on each paddle allows the tester to easily administer the test.

Grating levels printed on each handle are: 0.25, 0.5, 1.0, 2.0, 4.0, and 8.0 cpcm (cycles per centimeter of surface).

Includes: instructions and storage case.

Four paddles printed on both sides. 8" (20.3 cm) diameter.
