Snellen Eye Chart 20x26
POPULAR ITEM: Hang this 20 x 26 (51 x 66 cm) eye chart in medical offices or use as nostalgic decoration in the home office of ophthalmologists. Variations of the Snellen chart are routinely used by optometrists and other eye care professionals to measure visual acuity.
The patient covers one eye, and reads aloud the letters of each row (within the white area), beginning at the top. Smallest row that can be read accurately indicates the visual acuity in that eye. The left vertical black strip numbers the lines; the right black strip identifies the point size that the patient can read at 20 feet.
