The diopter of the eyepiece needs to be adjusted because different people have different vision problems, so the diopter of the sighting telescope needs to be adjusted to obtain a clear view and an optimal observation effect. For myopes, the focal point of the eye is in front of the lens, so it is necessary to focus the light to a greater distance to see the distant object. When using a scope, they need to adjust the diopter of the lens so that the light is more quickly focused after being scattered by the lens, and a clear image is seen. Whereas for presbyopic subjects the eye is focused behind the lens, so it is necessary to focus the light to a closer distance to see the near object. When using a scope, they also need to adjust the diopter of the lens so that the light is scattered by the lens and then focused more quickly to the near point, thereby seeing a clear image.
