Contrast Sensitivity, CSV-1000HGT
CSV-1000HGT Standardized Glare Test
Since 1991, the CSV-1000 has been a mainstay for clinical trials that measure contrast sensitivity, ETDRS acuity, low contrast acuity and glare sensitivity. The self-standardized back lit system automatically initiates and maintains a light level of 85 cd/m2. This light level is recommended by the FDA for vision evaluation. The system is also easy to use and requires no maintenance, thus greatly reducing overhead in clinical trials. The cool fluorescent bulbs used in the CSV-1000 have a 20,000 hour life and draw very little energy. Using the CSV-1000 makes bulb replacement obsolete and creates an energy saving footprint. The device is also configured electrically with a universal power supply so that is very simple to adapt for local electrical requirements by using a plug cord for the country of choice.
