Description

Contrast Sensitivity plays an intricate part in everyday life. Testing contrast sensitivity helps to establish a record of what is normal for each patient, since everyone’s contrast sensitivity is unique. After establishing this accurate record for the patient, pinpointing abnormalities will be easier and can lead to quicker detection of vision problems. Abnormal contrast sensitivity results can help detect early signs of diseases such as Parkinson’s, Glaucoma, Cataracts and Glare problems, among many others.

Sloan low contrast vision test features equivalents on each side of the chart. These equivalents include Meters, Feet, LogMar, and Decimal. This list helps in easy translation and conversion of equivalents. Coupled with Sloan letters, true contrast levels and ETDRS style format, this contrast sensitivity test is accurate and reliable.

CAT. NO. 2425 Illuminator Cabinet is necessary with these translucent low contrast charts.

Low lighting often causes problems with patients that suffer from contrast sensitivity loss. In dimmed or low lighting, patients may not be able to make out furniture, read, or walk without running into items. Also, because patients with low contrast sensitivity may not be able to see other cars or pedestrians, driving at night would be very difficult. These symptoms point to an underlying problem with a patient’s vision and can be early signs of many types of diseases.
