However, you know what? For some times ,a careless simple action, will let the optical glasses damage. Therefore, as a senior glasses maker, here is the tips from us as a senior maker:

1.  Do not put your glasses in the sun under the front windshield of car.

No matter what kind of material of glasses can not afford such a strong high temperature,especially lenses. You will find that the lens will be tear apart when the concave-convex principle works.

2. Do not put your acetate frames in a strong high temperature or wet place

For the acetate frames, highly recommend not put it in a strong high temperature or wet place. because of principle of heat expansion and cold contraction , the frames will be deformed. 

3.For injected frames, like TR90, ultem or PC, not use it under overly cold place(Not less 0 degree centigrade or Not less than 32 degrees Fahrenheit)

What will be happened if you put injected frames under 0°C? Color or pattern on the surface`s frames will be falled away, and more badly, the frames is so easy to be broken because it become hard and crispy.

4. For metal frames, like copper, nickel, stainless steel, the seawater is their natural enemy. 

If your work environment has anything to do with the sea or the seawater, and you like metal frames, pls use Titanium optical frames which will not be easy eroded by seawater.
