[0042] Example 4 of spectacle lenses: ( Figure 15 is to help understand Figure 16 schematic diagram, Figure 16 is a schematic diagram of a compound spectacle lens) Figure 15 The above figure is an achromatic prism 12 that can eliminate or weaken chromatic aberration, which is composed of a prism 11 and another prism 10 (another material) whose base faces the opposite direction. (12 is composed of two different materials. ), the following figure is a schematic diagram of the prior art myopia lens 2. Figure 16 It is a schematic diagram of an achromatic composite spectacle lens 13 composed of an achromatic prism 12 and a prior art myopia spectacle lens 2 (the composite spectacle lens can be made of two kinds of materials or three kinds of materials), and it is made of two kinds of materials with different refractive indices. The formed two refracting prism bases are stacked and bonded opposite to each other to form a prism for eliminating chromatic aberration or reducing ...
