75 degrees of myopia after dilated pupils at the age of 10 is not serious. 75 degrees of myopia is a low degree of myopia, which has a relatively minor impact on a child’s life and does not lead to more serious complications in the child’s eyes, such as retinal detachment or retinal tears. Some children with better adjustment may be able to see objects at a distance clearly without the need for eyeglasses. However, if children’s myopia continues to develop, more serious complications such as retinal detachment and retinal tears may occur once they develop high myopia. Therefore, it is recommended that children usually see far-sightedness, such as reading the blackboard in class, wear myopia glasses in time to correct their vision, which can avoid excessive eye adjustment fatigue, and accordingly slow down the growth of myopia. At the same time, they should pay attention to their eye habits, participate in more outdoor activities, and review the changes in their vision every 3 to 6 months.
