The researchers proposed that preschool children who do not initially exhibit signs of anisometropia but have any degree of myopia, significant hyperopia and/or astigmatism should undergo at least one additional refractive measurement. “The significance of follow-up examinations grows with higher ...
Visual Acuity, Refractive Procedures, and Sudden Vision Loss Definition The state of an eye in which light rays are not properly focused on the retina, resulting in image blur. Ametropia Arefractive error(e.g., myopia,hyperopia, or astigmatism). ...

Among them 3 with double hypermetropia, 2 with emmetropia in one, and hypermetropia in the other eye. From Project Gutenberg Determination of refraction of the better eye is given in 6 cases, and showed twice emmetropia, twice slight myopia, twice hypermetropia. From Project Gutenberg On May...
b. hyperopia. c. hypoxia. d. myopia. Nearsightedness: Nearsightedness is an eye-focusing condition in which objects near the person appear clear, but objects far away appear blurry. This can be due to an eye that is longer than normal or a cornea with a steeper...
Refractive status was determined according to the cycloplegic spherical equivalent (SE) of the eye with less SE and classified into myopia (SE ≤-0.5D), emmetropia (0.5D > SE >-0.5D), or hyperopia (SE ≥0.5 D). Results : Among 20,419 preschoolers from 2014 through 2019, a total of...
