For testing at 3 meters (10 ft.)
Acuity range 25M to 5M (20/160, 6/48 to 20/10, 6/3 equiv.)
Two smaller groups 6M to 1.5M for repetitive testing (20/40, 6/12 to 20/10, 6/3 equiv.)
Test includes a soft-tipped pointer, recording forms (CAT. NO. 2514) and test instructions
Measures 23 X 35.5cm (9 X 14 in.)
CAT.NO. 914 Small Illuminator Cabinet is necessary with these low contrast charts
Traditional Sloan lettering
Helps to assess contrast sensitivity in a large range of ages
Usable in a clinical setting for measuring contrast sensitivity
Contrast sensitivity changes with a patient's age. Because of this constant change, patients should be tested regularly. Furthermore, low contrast sensitivity scores can help detect many different visual problems. Some problems that cause low contrast vision scores include contact lens problems, glaucoma, cataracts and more. By testing often, these problems can be detected sooner and have a higher treatability rate.
