Re: Night vision (Student question)

[Deborah Briihl]

What I have read is the opposite - Males appear to have better visual acuity under photopic conditions, while females have lower absolute thresholds under scotopic - and can be seen in childhood. Females also may dark adapt faster. There are other gender differences as well related to acuity. I'm pulling this information from:
Coren, Ward, & Enns (1994) Sensation and Perception (4th ed.)

Folks,

Are there any explanations for variations in the acuity of night vision from
person to person (other than owning night vision goggles)?  

A student  asked what the explanation would be, according to her, her brother
and husband see better in the dark than she does . I also wonder since this
is a subjective and ancedotal account, if night vision has been studied with
this in mind (finding out who might have better than average night vision and
what neuroanatomical or neurochemical conditions would make this so.)

Thanks for any help you can give me.
