Western's most popular eye chart. Made on non-reflecting, matte finish cardboard with brass mounting eyelet, this visual acuity chart measures 11" wide by 24" high. The Snellen Letters are designed to be read at a distance of 10 feet, which is useful when exam room space is limited. A Standard 20 foot viewing distance Eye Chart
is available as well. Red and green bars not only serve as a reference point, but hint as to a patient's color perception.
