Rx:
- Right Eye: +2.75 -1.00 x 120
- Left Eye: +2.50 -0.75 x 110

Add: +2.25

The patient has requested a pair of single vision lenses to use exclusively for reading at the near point. What will be the power of these lenses?

A. +5.00 -1.00 x 120 / +4.75 -0.75 x 110
B. +5.00 sph / +4.75 sph
C. +5.00 -1.00 x 30 / +5.00 -1.00 x 30
D. None of the above

The power of single vision reading lenses based on the given prescription would be +5.00 spherical for the right eye and +4.75 spherical for the left eye.

To creating single vision lenses for reading based on a complex prescription that includes astigmatism correction. The provided prescription is +2.75 -1.00 x 120 for the right eye (traditionally denoted as OD) and +2.50 -0.75 x 110 for the left eye (OS), with an additional reading add of +2.25.

To compute the power for reading glasses, we simply add the reading add to the spherical component of each eye's prescription. Therefore:

Right eye: +2.75 (sphere) + +2.25 (add) = +5.00 spherical
Left eye: +2.50 (sphere) + +2.25 (add) = +4.75 spherical

The correct answer for reading glasses, which only considers the spherical power needed for near vision, is B. +5.00 sph for the right eye and +4.75 sph for the left eye.

The astigmatism correction and axis are not relevant for single vision reading lenses, as they are designed to focus solely on near objects.
