| Description | Designed by: Dr. August Colenbrander Conventional, high-contrast letter chart acuity captures only one aspect of visual performance. Low contrast acuity is equally important for activities of daily living, since most everyday objects have less than | Precision Vision offers a variety of Low Contrast and Mixed Contrast Eye Charts for testing Contrast Sensitivity. Notations for testing at Near Vision, 1 meter, 2 meters, 2.5 meters, 3 meters, 4 meters and Multi-distance. Products range from Flip | Developed by Jeff Rabin, OD, PhD,US Air Force School of Aerospace Medicine This Super Vision test includes visual acuity and letter contrast sensitivity (CS) on a single chart. The top portion of the chart tests for acuity vision while the bottom | Contrast sensitivity vision test includes a legend card for easier recordings. Also, eye test features five levels of contrast for more precise diagnosis of contrast vision. Chart also uses Sloan optotypes that are highly reliable and repeatable. |
