① At noon in summer, place your glasses on the dashboard of your car.

② Wear glasses or keep them by your side when taking a sauna, shower, or hot spring.

③ The oil temperature during cooking in the kitchen is very high, and if it splashes onto the lens, it will immediately burst the film.

④ When eating hot pot, if the hot soup splashes onto the lens, it will also burst the film.

⑤ Place glasses for a long time next to hot household appliances, such as desk lamps, televisions, etc.

In addition to the above points, the cheapest eyeglasses online should also be kept away from liquids containing strong acids or alkalis to prevent corrosion of the frame or lenses.
