Myopia glasses are concave lenses, while hyperopia glasses are convex lenses; Deep degree lenses are thick, while light degree lenses are thin; Can you measure the degree of each of its two lenses separately: take one lens facing sunlight, place a piece of paper on the other side, and change the distance between the lens and the paper until the light spot on the paper becomes the smallest and brightest. Measure the distance from the smallest and brightest spot to the convex lens, which is the focal length of this presbyopia lens. The reciprocal of the focal length is the lens focal length. Multiplying the lens focal length by 100 is the degree of the lens, and the degree of the other lens is also measured in this way. By measuring the degree of two lenses, it is known that they are not the same degree.
