Q. My dogâs eyes are red. A. Dr. Nunnery: Changes in the color of the eyes can be disconcerting. In fact, itâs one of the most common eye concerns that compel owners to bring dogs to the vet.. My dog has been squinting, as well as rubbing, his eyes. A. Squinting or holding the eye shut usually indicates ocular pain, which can be intense because there are so many sensory nerve endings on the corneaâs surface.
For good day and night vision an animal such as the bobcat must have an abundance of both rods (light receptors) and cones (color receptors) in its eyes. The cones allow it to distinguish color, see fine details, and detect movement. The rods respond to changes in light intensity and add to its ability to see at night.
