The pupil of the human eye can vary in diameter from 2.00 mm in bright light to 8.00 mm in dim light. the eye has a focal length of about 25 mm, and the visible spectrum extends from 390 nm (violet) to 750 nm (red). note that the light-sensitive cells on the retina have radii ranging from 0.75 μm to 3.0 μm.
