As I age, the nearpoint for my eyes is moving out. I can read items fine at 45.0cm from my cornea, but I want to read at 25.0cm with my new reading glasses. I wear my glasses 2.00cm from my cornea, and my retina is 3.50cm behind the cornea. (Picture not to scale)
A) What is the focal length of my eye system? Treat it as a simple lens at my cornea. What is my eyes' refractive power in Diopters?
B) What is the refractive power of my new reading glasses? What kind of image does it form for my eye to see? What is the nature of the image made by the glasses (Inverted/Erect, Magnified/reduced, real/virtual)?
