The light is focused by the lens system of the eye into an inverted image at the photosensitive ____
A
Cornea
B
Eye muscle
C
Optical Nerve
D
Retina
Explanation: 

Detailed explanation-1: -The crystalline eye lens acts as a light-sensitive screen by forming an inverted true image of the item on the retina. The light that enters our eyes is converted by the retina into electrical impulses that our optic nerve transmits to our brain, which produces the images we see. It’s a crucial element of our vision.

Detailed explanation-2: -The pupil changes size according to how much light is present; it is smaller in bright light and becomes larger when there is less light. As the cornea is curved, it bends the light entering the eye, creating an upside-down image on the retina.

Detailed explanation-3: -The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.

Detailed explanation-4: -The image formed by the eye lens on the retina is real, inverted, diminished.

Detailed explanation-5: -The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina. The retina receives the image that the cornea focuses through the eye’s internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain.
