Pay attention to cosmetics: cosmetics or cosmetics and other chemical cosmetics can easily discolor or deform the frame. Please wipe it off with a special cloth or paper for glasses. 2. When the frame is folded: most of the glasses are gently folded from the left side of the lens. If the frame is folded from the right side first, the frame itself will be unbalanced and skewed, making it uncomfortable to wear. 3. The correct position of the glasses on the face: In order to give full play to the correct function of the glasses, the optical center of the lens is made in the part that suits your eyes, please wear it in the correct position 4. Use both hands when taking and wearing the frame: Do you often take and wear glasses with one hand? If you use one hand to take and wear glasses, it is easy to deform the frame 5. Don't put it in a hot place: Don't put it in a heating room or a place easily exposed to the sun for a long time, because the frame is easy to change color or deform under the contact of light and heat. 6. When there is wind and sand on the lens when wiping the lens, please rinse it with water, and then dry it with a special cloth or paper for glasses 7. When placing the glasses: Do not put the convex surface of the lens downwards, fold it in the opposite direction of wearing it, and put the lens upwards. When not in use, try to put it in the glasses case. ------------------------------------------------------------------------
