How often do children’s glasses need to be changed?

There is no fixed standard for the replacement time of children’s glasses, and it is necessary to comprehensively judge the changes in the child’s vision, the degree of wear of the glasses and other factors. The following are some common reference situations:
Visual change
Children are in the stage of growth and development, and their vision changes more frequently. It is generally recommended to take your child for an eye exam and optometry every six months to one year. If the degree changes more than 50 degrees, it is usually necessary to consider replacing the glasses to ensure that the child can obtain clear vision, reduce eye fatigue, and prevent further deepening of the degree.
For children with rapid myopia progress, there may be significant changes in less than half a year, and glasses need to be replaced in time. For some children with relatively stable vision, the degree change may be small for a year or even longer, and the frequency of glasses replacement can be relatively low.

Wear degree of glasses
The lens appears more scratches, wear or film off, will affect the optical performance and clarity of the lens, even if the degree does not change, it is recommended to replace the lens in time to ensure the visual quality of the child.
The frame deformation is serious, can not be adjusted to the proper state, or the frame is damaged, broken, etc., will affect the wearing comfort and correction effect of the glasses, need to be replaced with a new frame, or even replaced with the lens.
Child growth and development
As children grow older, their facial bones and features continue to develop. If the size of the glasses is not appropriate, such as the frame is too tight or too loose, pressing the child’s face or often slipping, affecting the wearing experience and visual effects, it is necessary to replace the appropriate glasses according to the child’s facial size.

In short, parents should pay close attention to their children’s vision and the use of glasses, follow the recommendations of professional optometrists or ophthalmologists, and replace appropriate glasses for their children in a timely manner to protect their children’s vision health.
