Today's question is:

In general, do the resin lenses we wear have a useful life?

No

Yes

Answer: yes

Analysis: the resin lens of frame glasses will be aged and yellowed for a long time, and there may be scratches or deformation, so that the light that normally passes through the lens decreases. Long-term use of such lenses may cause discomfort in the eyes, resulting in chronic visual fatigue and visual fatigue syndrome. Therefore, the resin lens has a service life.
