On a computerized optometry checklist, SE refers to the refractive error that the computer recommends for correction. s stands for hyperopia, -S for myopia, and E for esotropia. The result of a normal visual acuity examination is 0. The presence of a number indicates nearsightedness or farsightedness, e.g., SE+1.25 in the right eye indicates 125 degrees of farsightedness in the right eye, and SE-0.50 in the left eye indicates 50 degrees of nearsightedness in the left eye. If the examination reveals that the myopia is not “pseudomyopia”, the need for glasses and their prescription should be assessed according to the results of the visual acuity examination. In general, if the visual acuity is below 0.6 and the degree of myopia is more than 50 degrees, you need to consider wearing glasses to correct the myopia. Eyeglasses should be worn properly under the guidance of a physician, and care should be taken to protect the eyes from over-exertion.
