The CSV-1OOOE contrast sensitivity chart test face is the most widely used contrast sensitivity test in the world. This test provides for four (4) rows of sine-wave gratings. At the recommended test distance of 8 ft (2.5 meters), these gratings test the spatial frequencies of 3, 6, 12 and 18 cycles/degree.

The CSV-1OOOE provides a full contrast sensitivity curve, which is very useful for the evaluation of ocular disease (particularly cataracts, glaucoma, optic neuritis, diabetes and macular degeneration), contact lenses and refractive surgery.

The CSV-1000RS test face is used widely for screening refractive surgery patients. The test presents ETDRS LogMAR acuity from 20/10 to 20/100 and one row of spatial frequency at 12 cycles/degree.

The patient can be easily screened in the examination chair for ETDRS acuity and contrast sensitivity. If a contrast sensitivity deficit is found, retesting the patient with all four spatial frequencies using the CSV-1000E is recommended.

The CSV-1OOOS test face is widely used for in or out-of-office screenings and for cataract evaluation. This test presents standard visual acuity from 20/15 to 20/200, two rows of spatial frequencies (6 and 12 cycles/degree) and a real-world driver's scene.

The CSV-lOOOSLanC test face provides the same tests as the standard CSV-1OOOS, except that the acuity test is presented in Landolt C format.

The CSV-lOOOCVA test face is used to evaluate both contrast sensitivity and low contrast acuity.

Three contrast levels (high, 25% and 12.5%) of LogMAR acuity (20/16 to 20/100) are presented on the test face as well as the two spatial frequencies of 6 and 12 cycles/degree

The CSV-1000-1.5CPD is a special test face designed specifically for Food and Drug Administration clinical trials.

At the recommended test distance of 8 feet, the gratings test one spatial frequency of 1.5 cycles/degree.
