This is in contrast to nyctalopia (nighttime blindness), where vision is lost in low light conditions. Daytime blindness is characterized by a significant decrease in visual acuity in the eye exposed to the eye, while their vision remains relatively normal in low light or nighttime conditions. Causes of Day Blindness The most common causes of day blindness (hemeralopia) are vitamin and mineral deficiencies and certain genetic developments can cause hemeralopia, chronic or long-term injury or disease affecting the accessory nerve can also cause day blindness.
