Final answer:
The patient has hyperopia, a condition where they can see distant objects clearly but struggle with close vision. Prescription glasses or contact lenses with a positive diopter can correct this issue, or refractive surgery might be considered. The eye's accommodation ability affects the focusing power for various distances.
Step-by-step explanation:
The patient you are describing appears to have a vision problem known as hyperopia or farsightedness, where close objects appear out of focus, while distance vision remains unaffected. To optimize vision for such patients, corrective measures such as eyeglasses or contact lenses are typically prescribed to converge light more effectively on the retina. In some cases, refractive surgery like LASIK might be recommended, depending on the patient's preferences and suitability for the procedure.
For patients with hyperopia, the near point of clear vision is further than normal. Glasses or contact lenses for these individuals would have a convergent or positive diopter prescription to help focus light correctly on the retina. The precise diopter value required can be determined through a comprehensive eye examination.
Furthermore, the concept of accommodation or the eye's ability to change its focusing power to see objects at various distances is crucial. For individuals to be able to switch focus from distant to near objects, their eyes adjust the power of the lens; however, those with hyperopia may struggle due to insufficient refractive power.
