Understanding Accommodation in the Human Eye

What is the primary function of accommodation in the human eye?

• To adjust the optical power of the lens

• To change the color of the iris

• To alter the shape of the cornea

• To modify the size of the pupil

When viewing distant objects, how do the light rays enter the eye?

• Converging towards the lens

• At a sharp angle

• In a scattered manner

• Parallel to each other

What characteristic of the lens is necessary for focusing on distant objects?

• The lens must be thick

• The lens must be flexible

• The lens must be thin

• The lens must be opaque

How do light rays behave when focusing on nearby objects?

• They converge before reaching the lens

• They scatter in all directions

• They come in at a sharp angle

• They enter parallel to each other

What change occurs in the lens when focusing on nearby objects?

• The lens becomes rigid

• The lens becomes thinner

• The lens becomes thicker

• The lens becomes transparent
