The style of prescription glasses
Choose the material, and then choose the style. The width of the appropriate frame should match the distance between the two pupils to ensure that the eye can pass through the optical center when looking at things. Choose the right style according to your face shape. Generally follow the complementarity principle, such as choosing square frames for round faces and round frames for square faces. After choosing the frame, you should try it on for a while to see if the weight is appropriate and the style is suitable.
Use your two hands to wear and take off the glasses.
When you pick and wear glasses, you need to grab the temples with both hands and take them off. When you pick and wear glasses with one hand, it is easy to cause deformation and loosening of the glasses. According to the convention of international glasses design and manufacture, you should fold the left temple first. When placing glasses, keep the convex side of the lens up to avoid scratches on the lenses.
