Question

Quizplus · Accepted Answer

The lens of the eye does have convex surfaces.

Answer: B 
 The lens is stronger when it bulges more, not when it's flatter.

Answer: C 
 The lens of the eye is responsible for refracting light the most, accounting for approximately two-thirds of the eye's total refractive ability.

Answer: D 
 This statement is incorrect. The eye adjusts the lens flexibility to focus on objects at various distances, with a more flexible and bulging lens being used for close-up objects and a flatter and less bulging lens being used for distant objects.
