Solve the following questions given below:
Question 1: What power contact lens is needed to correct the vision of a person who has a near point of 71.0 cm and allow him to see objects 25.0 cm away?
Question 2: If this person has a normal 8.00% ability to accommodate (increase) the power of his eyes, what is the maximum distance of objects he can see clearly with his contact lenses and with totally relaxed eyes? (Assume a lens-to-retina distance of 2.00 cm. If he can see very distant objects clearly, enter 'infinity'.)
Please explain the equations and steps are used to get the answer. Thanks!
