Answer 1

Step 1: Human Eye Lens System Function:
The human eye's lens system, analogous to a camera lens, concentrates light onto a light-sensitive layer. This system comprises the cornea, lens, and other elements that facilitate the focusing of external light onto the eye.

Step 2: Retina's Function:
The layer that receives the focused image, which is sensitive to light, is termed the retina. It houses photoreceptor cells, namely rods and cones, responsible for detecting light and transmitting visual signals to the brain.

Step 3: Summary:
The human eye's lens system produces an image on the retina. This image is subsequently processed by the retina, and visual information is relayed to the brain for interpretation.
