Description

Two smaller groups 10/20 to 10/8 for repetitive eyesight testing (20/40 to 20/16 equiv.).

This translucent eye chart uses Sloan optotypes for accurate testing. Each optotype has been calibrated for size, difficulty, threshold blur, and dimension. Each line is arranged equally. This eye test also includes two smaller groups for repetitive testing without memorization.
