prism glasses, sunglasses, telescope mirrors

With the help of prism glasses, reclining glasses or telescope mirrors, the field of vision is extended or the angle of view is changed.

For neck problems, the viewing angle can be changed up to 90 degrees, allowing reading 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 any visual defects, but merely extend the angle of vision.
