A hyperopic eye with an optical power of 58.00 D would most likely be prescribed a spectacle lens with how many diopters?

A hyperopic eye with an optical power of 58.00 D would most likely be prescribed a spectacle lens with how many diopters?

• A. +1.00
• B. +2.00
• C. +3.00
• D. +4.00

Answer: (B)

Hyperopia requires extra converging power to move the focal point forward onto the retina. For distant vision, the eye’s total refractive power is typically about +60 diopters. If the eye’s own optical power is +58 D, you add +2 D with spectacle lenses to bring the total to the ~+60 D needed. That’s why +2.00 D is the correct prescription. A +1.00 D lens would leave the system at ~+59 D and won’t fully correct the hyperopia, while a +3.00 D lens would overshoot to ~+61 D, potentially causing blur.
