About Prism Glasses
The refractive index of the same medium is different for different colors of light. Different colors of light travel at different speeds in the same medium. Because the same medium has a different refractive index for various monochromatic light, and the deflection angle of each monochromatic light is different when passing through a prism. Therefore, white light through a prism will separate the monochromatic light, known as dispersion. What is the prism effect of glasses? As long as there is a deviation between the visual channel of the eye and the optical center of the lens, it can produce a prism effect. Therefore, the severity of the prism effect can be used to measure whether the glasses with the correct prescription are processed correctly and reshaped correctly.
