(N/A) The human eye adapts to different light intensities using two types of photoreceptor cells located in the retina: rods and cones.
$1$. Rods: These cells are highly sensitive to dim light but do not perceive color. They allow us to see in low-light conditions (scotopic vision).
$2$. Cones: These cells are sensitive to bright light and are responsible for color vision and high-acuity detail. They function effectively in well-lit conditions (photopic vision).
Additionally,the iris regulates the amount of light entering the eye by adjusting the size of the pupil.
