Teenagers and children's frames from kids eyeglasses online advocate using lightweight materials. In addition to aesthetic requirements, the shape and style of the frames should ideally match the child's pupil distance.

A mirror frame that is too small can cause local compression on the face, causing discomfort in children and affecting facial development; A frame that is too large can cause the lens to shift too much, resulting in a significant difference in thickness around the lens and worsening of visual deformation in the surrounding area, affecting vision and field of view.

Teenagers and children should choose lenses with different refractive indices according to different degrees of kids' eyeglasses online; For moderate to low myopia, it is decided whether to always wear glasses according to the situation. For medium to high myopia, it is necessary to wear glasses when looking up and far; The selection of functional lenses depends on individual needs.

The essence of dilated refraction is to relax the fatigue caused by prolonged excessive tension of the eye muscles, thereby obtaining the true refractive state of the eye. This is mainly because teenagers have a strong ability to adjust their eyes.

Suppose the pupils are not dilated during optometry. In that case, the regulatory effect of the ciliary muscle can make the lens convex, enhance refractive power, and cannot remove the components of regulatory myopia, also known as pseudomyopia, which affects the accuracy of the results.

The precautions and principles for optometry and glasses selection for teenagers and children. In addition, parents are reminded to take their children for regular examinations at the best place to buy eyeglasses after glasses selection. Especially for children with high myopia, not only do they need to undergo refractive index tests every year, but they also need to undergo fundus examinations.
