Question

Most of the bending (refraction) of light rays which enter our eyes is done by A. The eye lens B. The retina C. The fovea D. The cornea

Geranium plants are perceived by our eyes to change color during the day, going from looking more reddish during daylight to looking more violet/bluish at dusk. Why?

During the day their color is detected by the cones in our eyes, which are more sensitive to red light, while at dusk they are detected by the rods, which are more sensitive to bluish light

During the day the resonance frequencies of the plants match red light, but that changes over to blue light during at dusk
