The normal value of the refractive sphere lens in the right eye is 0, which means that there is no refractive error, and usually a range of -25 degrees to +25 degrees is considered normal. Refractive sphericity is defined as myopia or hyperopia. If the refractive sphericity is negative, it is myopia, and if the refractive sphericity is positive, it is hyperopia, and there is no refractive power in the normal range of vision, i.e., the refractive sphericity is 0 degrees. Refractive error exists because of myopia or hyperopia, where the light entering the eye is not clearly rendered on the retina. If the refractive error in the right eye is too large, you should go to the hospital for examination and timely correction, you can choose to wear frame glasses, corneal contact lenses or myopia surgery, pay attention to eye health in daily life, reduce the use of electronic products, avoid staying up all night and other bad habits.
