Night Blindness

About This Condition

People with night blindness (also called impaired dark adaptation) see poorly in the darkness but see normally when adequate amounts of light are present. The condition does not actually involve true blindness, even at night.

Symptoms

Symptoms include difficulty seeing when driving in the evening or at night, poor vision in reduced light, and feeling that the eyes take longer to “adjust” to seeing in the dark.

Other Therapies

Therapy includes management of any underlying medical condition.
