Diseases such as Parkinson's, Glaucoma, Cataracts, and problems with Glare all have early warning signs that can be detected through low vision contrast sensitivity testing. Lowered contrast sensitivity can not only point out these diseases, but it can have major effects on everyday life. Early detection can lead to earlier diagnosis and even earlier treatment. Without contrast sensitivity, many everyday situations like driving and reading are challenging. Regular contrast testing can establish an accurate record for each patient, and make it easier for detection of contrast sensitivity loss and disease.
