| Description | Each line on the Rabin Contrast Sensitivity Test is a lower contrast than the one before it, using Log CS steps. This progression in contrasts helps to identify the patient's contrast sensitivity. Furthermore, the test helps to detect subtle effects | 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 | 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. |
