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.
