A 6-year-old child with no reserve for farsightedness can be treated by improving his eye habits and wearing glasses for correction. Improve eye habits by reducing prolonged close reading, computer and cell phone viewing, and participate in more outdoor activities. In addition, go to the hospital regularly for refraction and eye-axis length checkups. Based on the results of the checkups, formulate measures to prevent the development of myopia, and then wear frames or contact lenses to improve the corrected visual acuity and avoid further reduction of the reserve of hyperopia. A 6 year old child with no reserve of hyperopia will easily develop myopia in his/her eyes, and in the long run, he/she will develop high myopia or even ultra-high myopia. Under normal circumstances, a 6-year-old child should have about 100 degrees of farsightedness reserve, which is a godsend to avoid the occurrence of myopia, so farsightedness reserve is very crucial. It is recommended to take your child to participate in more outdoor activities, go out and look at the blue sky and green plants outside, and look at cell phones and computers as little as possible.
