Problem: Stretched-Out Plastic Sunglasses

               塑料太阳镜变形

Solution: Immerse the sunglasses in hot water, or blast them with a hair dryer until the plastic starts to become flexible, then slowly and gently bend the frame back into shape.

处理方法：把太阳镜浸入热水中，或者用吹风机吹，当塑料开始变得有弹性的时候，轻轻地把镜架调到原来的位置，晾凉即可。
