Multi focus reading glasses

Multi-focus color-changing reading glasses are a combination of multi-focus lenses and color-changing glasses, the following is a detailed introduction to it:
How it Works:
Multi-focus principle: The lenses of multi-focus reading glasses have a number of different focal degree areas from top to bottom, which are generally divided into the far light area, the transition area, and the near-light area. The far light area is used to see distant objects, such as watching scenery, watching TV, etc. The transition zone is an area of gradual change in degree, which facilitates the transition between seeing far and seeing near; The near light area is used to see close objects, such as reading books, looking at mobile phones and so on. This design allows the wearer to obtain relatively clear vision at different distances, without frequent replacement of glasses

Discoloration principle: The discoloration function is achieved through the discoloration factor in the lens. In a weak light environment such as indoors, the lens remains transparent or lighter in color, which does not affect the normal visual effect; When in the outdoor UV strong environment, the color change factor will have a chemical reaction, make the lens color darker, play a role in blocking ultraviolet light, reduce glare, and protect the eyes.
Advantages:
Convenient and practical: a pair of glasses at the same time have the function of seeing far, seeing close and seeing things clearly at different distances, and can also automatically change color according to the light intensity, whether indoors or outdoors, can meet the needs of the wearer, avoiding the trouble of frequently replacing glasses with different functions.
High visual quality: The multi-focus design can provide continuous clear vision, avoiding the visual jump feeling of traditional double-light reading glasses when switching between different areas, so that the wearer's visual experience is more natural and comfortable.
Beautiful appearance: Compared with traditional single-light reading glasses, the appearance of multi-focus color-changing reading glasses is more similar to ordinary myopia glasses, there is no obvious lens boundary, more stylish and beautiful, and it is easier to be accepted by the wearer.
