I am just beginning to read about the path that light takes to the substantia nigra and the affects light can have on various dopaminergic pathways in the brain. The lions share of literature regarding light therapy-red--near infrared wavelengths is geared towards beneficial effects on sleep- EDS, etc-- i was wondering of anyone has researched this further and if occluding the "good" eye-- to force "use" of the amblyopic eye might have any beneficial effects.

Interestingly, there seems to be a signal shooeing increased PD in people with occupations associated with bright light exposure and less PD incidence in the blind
