Someone with hyperopia has a prescription of .8D for lenses that are 1.5cm from their eyes. What is their near point?

Expert Solution

Sign convection :--

Everything on right is taken as positive.

As object is on right side of lens so object distance is taken as positive.

Everything on left of lens is taken as negative. Image will be formed on left side of lens so taken as negative.

Image formed

Object distance = (Dmin - Dl)

Image distance = -(DN- Dl).

D(N)= distance of near point of hypermetropic eye.

Distance between near point and eye.
