The Letter Contrast Sensitivity Testing on the Smart System uses standard Snellen and Sloan Letters presented at contrast levels from 100% to 0.8% contrast. The contrast of the monitors are precisely calibrated to give you consistent, repeatable results from visit to visit.
Presenting spatial frequencies of 18, 12, 6, 3 and 1.5 cycles-per-degree with contrast levels from 100% down to 0.8%, this easily administered test provides a great method for monitoring CSF, whether to monitor cataracts or assess quality of vision. Can be integrated with our GTS (Glare Testing System).
The new CSV-1000 HGT has been redesigned with a modern look including integrated glare lights. The CSV-1000 HGT still provides the ability to detect and quantify subtle changes in vision. Patented photocell circuitry automatically monitors and calibrates instrument testing light levels.
