So I added details of the OM-1, OM-2, OM-3 and OM Mention of these cameras are important because of their unprecedented influence on the overall design and direction of SLR cameras specifically and broadly. shining light into one's eye causes pupil to constrict (direct) and other pupil to constrict as well (consensual) light activates retinal ganglion cells axons w/in optic nerve (synapse on nuclei of pretectal area) CN III lesions - loss consensual reflex CN II - loss of direct. vision and optic reflexes The eyes are truly remarkable organs. Their light-sensitive retinas are able to convert light rays from objects in the visual field to impulses on the optic nerves, which ultimately give rise to images in the visual cortex of the brain. When both pupils contract/dilate in response to a stimulus or lack of stimulus to one eye. Shining the light on one eye sends a signal to the brain telling the brain that there is a bright light and the brain responds by sending a signal to constrict both eyes.
