Prism glasses, recumbent glasses, telescopic mirrors

The field of vision is expanded or the viewing angle changed with the help of prism glasses, reclining glasses or telescopic mirrors.

If you have neck problems, the viewing angle can be changed by up to 90 degrees, allowing you to read in a lying position. However, they do not compensate for any visual impairment, which is why it is still necessary to wear normal glasses. They do not compensate for visual defects, but merely widen the angle of vision.
