Hey, no worries! I'll do my best to help you out with this important question for your 10th board exam. Let's break it down:
(a) The power of an eye to see nearby objects diminishes with age due to a condition called presbyopia. As we get older, the lens in our eye becomes less flexible, making it harder to focus on close-up objects.
(b) The defect is called presbyopia, which is a type of farsightedness that occurs with age.
(c) Unfortunately, I can't draw a diagram here, but I can describe it to you. To correct presbyopia, a convex lens, also known as a reading or bifocal lens, is used. The lens helps to converge the light rays onto the retina, allowing for clearer near vision.
I hope this helps! Good luck with your exam, and if you have any more questions, feel free to ask.
