Although there are currently aging quenching processes to delay the yellowing of lenses, the process of lens yellowing is irreversible. What is the shelf life of glasses?

Children and adolescents should change their lenses or kids eyeglasses near me promptly as their myopia deepens. It is best to retest their refractive power every six months, and if there is a change of more than 50 degrees, they should be replaced.

Many people do not easily change their glasses unless necessary, but research shows that not changing glasses promptly can directly affect visual health.

Whether it is nearsighted glasses or sun visors, when there are scratches, coating fading, lens wear and blur, a significant decrease in transmittance, etc. on the lenses, the wearer should replace them promptly, otherwise it may hurt vision.

Because scratches on the mirror surface of glasses can significantly affect their optical correction performance, regular maintenance and replacement of glasses are necessary to ensure that they are always in good working condition.

So, what are the hazards of not changing glasses for a long time? What is the 'shelf life' of a pair of glasses? How to protect the lenses well?

Taking the popular resin lenses in the eyeglass mart as an example, due to material reasons, the lenses will undergo a "yellowing" phenomenon over time. The biggest problem with the yellowing of resin lenses is the occurrence of color deviation in human visual perception.

Due to the occurrence of color cast, the human eye will have an additional burden to adapt to this color deviation, thereby increasing eye function and visual fatigue. Long-term wearing of yellowed lenses can increase the possibility of myopia, especially childrens glasses for growing adolescents.
