Nyctalopia is the medical term for the condition more commonly known as Night Blindness.
Nyctalopia, also known as "Night Blindness" is the inability (or severely reduced ability) to see in low-light levels, such as at dusk and at night.
Note that those affected can, in the absence of other conditions, see to a normal extent during typical "daytime" light-levels .
