The glasses lens is yellow, do I need to replace the glasses?

The direct way for spectacle lenses to turn yellow is to replace the lenses! The longer the lens is worn, the higher the deterioration rate (the lens will also deteriorate). After the lens deteriorates, its optical performance will be weakened, which will affect the vision of the eye.

Lenses that have been overdue will also be discharged. The lens also has a service life, and it will change if it is overdue.

Normal adults’ myopias should be replaced once a year and a half to two years; adolescents are at the peak of eye use, so they should be replaced every 3 months to half a year; for the elderly, it is recommended to replace them once a year.

Lenses that are worn for a long time will generally have scratches and other wear conditions. Wearing such lenses will affect vision, so it is better to replace the lenses in time.

So, if the lens is yellow or worn, just change the pair of lenses.
