The eye is able to view varying degrees of light intensity and colors due to the presence of rod and cone cells present within the retina of the eyeball. Rod cells are responsible for night vision and cone cells are responsible for more detailed, trichromatic vision. Utilizing a combination of these cells will not damage the eye. Watching TV in the dark at the correct distance is not damaging. Please note that prolonged viewing of any single object can cause eye strain, which once again can be damaging to the eye; this should not be confused with the act of watching TV in the dark.
