Avoid damaging the frames or lenses due to excessive force. Folding the frame should start from the left.

1. The distance between the two temples of glasses and the curvature of the temples must be appropriate. Wearing glasses cannot Too loose or too tight. The eyes must be facing the optical center of the lens, otherwise the prism effect will occur, causing symptoms such as visual distortion, dizziness, dizziness, eye soreness, fatigue, and even strabismus.

2. Do not dry wipe the lens if there are fingerprints or oil stains on it. Dry rubbing will easily scratch the lens. It is recommended to rinse the glasses with clean water or low-concentration neutral detergent, then use paper towels to absorb the water, and then wipe them dry with a special glasses cloth. Remember not to rinse with hot water, as this can easily cause the lenses to peel off.
