Method of taking off the contact lens
Wash your hands before removing contact lenses, and be careful not to leave long fingernails, to avoid contamination of the lenses by bacteria and nail scratches. Look up, open the upper and lower eyelids with the left index finger and right middle finger. Pinch the middle and lower edge of the lens gently with the thumb and index finger of the right hand, and remove the lens. You can use the index finger first to move the lens down, and then gently pinch the middle and lower edge of the lens with the thumb and index finger belly, and take off the lens.
How do bifocal reading glasses work?
Bifocal reading glasses have two different lenses on the same lens. The top of the lens is your normal distance prescription, while the bottom is for close-up viewings, like reading. The two lenses allow you to alternate between them by moving your eyes up and down as needed. A bifocal lens is a type of lens that has two different areas of vision: one for close range and one for long-range. Typically, the upper section covers remote vision and the lower section covers reading. With a traditional bifocal lens, you can see the difference between the two lenses because the lower curve is a little different.

Put into the lens box when not in use.
When taking off glasses, many people will easily hang them on the head, collar, or casual display, so that glasses often suffer a variety of damage. To do this, fold the glasses and place them face up in the case. Do not place your glasses in direct sunlight or in high temperatures, as heat can easily peel off the film on the lens. For example, in summer, the glasses are exposed to direct sunlight in the car for a long time, which is easy to cause lens stripping.
Progressive multifocal glasses are more powerful.
