In order to cater the variegated demands of our clients, we are offering an excellent quality range of Pelli-Robson Contrast Sensitivity Chart.

Other Details:

  • Features Traditional Sloan Optotypes
  • For use at 100cm (1m)
  • Includes two charts which may be wall or easel mounted and score sheets.
  • Illumination of 85 cd/m² is key to good results
  • Designed by DG Pelli, JG Robson and A J Wilkins, because they see contrast sensitivity as a realistic assessment of how well the patient sees large faint objects.
  • The chart follows the luminance, font, and letter spacing recommendations of the Committee on Vision of the National Academy of Sciences and National Research Council (Adv. Ophthal 41, 103-148, 1980).
  • The letter sequences are organized into groups of three (triplets) with two triplets per line. Within each triplet, all letters have the same contrast. The contrast decreases from one triplet to the next, even within one line.
  • The testing of contrast sensitivity on a regular basis is key to detecting early signs of diseases such as Parkinson’s, Glaucoma, and Cataracts. By testing with several different contrast levels configured together, the patient’s contrast sensitivity level is better assessed and records will be more precise.

The CSV-1000 instrument is the recognized world-wide leader for standardized contrast sensitivity, ETDRS and glare testing. The patented auto-calibration circuitry provides for standard and consistent test conditions without a hassle. The instrument automatically controls the test lighting to a level of 85 cd/m2, which is the light level recommended for vision testing by the National Academy of Sciences and adopted by the FDA as the required testing light level for clinical trials. Ease of use is one reason why the CSV-1000 is used in eye clinics in more than 60 countries. All you have to do is turn on the device and it is ready to evaluate patients using standardized and highly accurate tests.
