How long do plastic frames last?

Plastic frames are made of non-biodegradable materials and are possible to last forever.  If the frame is made of acetate, the layers of acetate fibers make the frame vary in degrees of transparency and pattern.  The plastic frame manufacturing process makes the plastic frame more brittle than the acetate frame. In this sense, the acetate frame has a longer service life.  Then the plastic, which is made of SAP, will never break down.  Depending on the circumstances, it could take years.  If the lenses are polycarbonate, the material takes hundreds of years to break down naturally. If TR-90 is normally stored, not exposed to the sun, and put in the box with cloth wrapped, and then you can keep 3 years, there is no effect.
