Question

If one lens is very different from the other, the centers must be placed accurately to prevent unwanted binocular prismatic effects. True or false?

Answer 1

False. If one lens is very different from the other, the centers do not need to be placed accurately to prevent unwanted binocular prismatic effects.

Step-by-step explanation:

False. If one lens is very different from the other, the centers do not need to be placed accurately to prevent unwanted binocular prismatic effects. Prismatic effects occur when light passing through a lens is refracted unevenly, causing the image to appear shifted or distorted. When the lenses are very different, the prismatic effects cancel each other out, resulting in a clear and undistorted image.
