1. Keanu is 47 years old, and the amplitude of accommodation in his left eye is about one standard deviation above average for his age. From now on, we concentrate exclusively on his left eye. When Keanu's eye is unaided by vision correction, he can focus on objects about 40 cm in front of it, but not closer. He has a Maximum Accommodation of 5 Diopters.

His eye sphere correction is +2.5D, he has a minimum power of 57.5 D (may not need to answer question)

1.5. Keanu wears a contact lens to correct his vision. The radius of curvature of the back surface of the contact is 8.8 mm. If the contact lens has an index of refraction of 1.65, what is the radius of curvature of its front surface in millimeters? Both the front and back surfaces are curved in the same direction as the cornea (bulging out away from the eye).

1.6. What is Keanu's far point distance (i) without vision correction and (ii) with vision correction?

1.7. What is Keanu's near point distance (i) without vision correction and (ii) with vision correction?
