Anisometropia refers to a condition when two eyes have unequal refractive power. Generally, a difference in power of one diopter (1D) or more is the accepted threshold to label the condition anisometropia. Patients can tolerate 3 D of anisometropia before it becomes clinically symptomatic with headaches, asthenopia, double vision and photophobia. In certain types of anisometropia, the visual cortex of the brain will not process images from bot… Web02. dec 2024. · During alternating defocus conditions, the eye was exposed to either 30 or 15 minute cycles of myopic and hyperopic defocus, with the order of defocus reversed …

Web20. jan 2024. · Monovision (also called blended vision) is nearsightedness in one eye. It can occur naturally, but it is often induced with corrective lenses or surgery for people who have developed presbyopia. Induced monovision can help people with presbyopia achieve an acceptable degree of clear near and distance vision without the use of bifocals.
