Monovision is used in treating presbyopia. Each eye is subjected to a different correction for the strength of the refraction of light for the purpose of preparing one eye for distance vision and the second eye for near vision. In short, an artificial step is made to create one nearsighted eye and one farsighted eye!
The eye will self-guide to distance and the second up-close. The patient’s preference is recognized before the operation, with the help of simulation with glasses or contact lenses. Finally, depending upon their vocation and personal feelings, the patient can decide if monovision is the best solution for him.
