Night blindness: Many people have more trouble seeing at night than during the day and have normal eyes. People with a small glasses prescription may not need it during the day, but the vision may be helped by using the prescription at night (driving, for example). Some people have trouble getting around in the dark, and have poor dark adaptation. It is possible that this could be from a retinal problem.

Vitamin deficiency: In addition to the other answers one can suffer vitamin deficiencies for a variety of reasons that can start as decreased night vision. This needs to be explored.
