Ophthalmology
In brief: Pupil size
Bright light in the eyes does indeed cause your vision via the pupil to get smaller. Less light coming through the smaller pupil is usually the normal natural response to keep from overwhelming the retina.
The peripheral field of vision is constricted with this respose and the central macula, needing the brighter level of light is in control.
