2153 SLOAN ETDRS Chart 4m 10 Percentage contrast
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.
