Many parents blindly pursue the same diopter for their children's eyes to achieve beautiful corrective effects when fitting glasses, but the diopter of each child's eyes is different.

We call children with binocular diopter over 100 ° -150 ° anisometropia. Astigmatism above 100 ° and spherical lens anisometropia above 150 ° may cause children's binocular images to be unequal

Causing a decrease in visual quality. After optometrists perform optometry on children, they also need to try on children's glasses based on the specific situation of the child's eyes, as each child's tolerance for binocular anisometropia varies.

Children don't have to choose to wear contact lenses because the safety requirements of contact lenses are relatively high during use, and some unscientific methods of use can cause serious damage to the cornea.

Especially young children should not wear contact lenses. Due to poor maintenance, cases of severe keratitis caused by wearing contact lenses are common, so do not wear contact lenses for the sake of aesthetics.

The corrected vision is not as clear as possible. Excessive corrected vision can often cause the eyes to feel bloated, sore, fatigued, and painful, and even lead to bloating, tightness, and headaches. A few people may also experience systemic symptoms such as lack of concentration, decreased memory, forgetfulness, and insomnia.

Therefore, childrens eyeglasses and corrected vision should generally not exceed 1.0, and it is recommended to have a reading range of around 0.8 to read the blackboard characters during class.
