Prismatic glasses are special glasses that help people with limited neck and back mobility to read books or view other materials without making an effort to raise their heads. They consist of two silver-plated glass prisms mounted in a frame.
The principle of operation of prismatic glasses is based on the fact that they change the direction of light rays entering the eyes in such a way that the image of a book or other material that is on the table in front of a person is reflected on the prisms and falls directly into the eyes. This allows a person to read while lying down, without having to raise their head.
Prismatic glasses can be useful not only for people with limited mobility, but also for anyone who often reads or works at a computer. They reduce strain on the neck and eyes, which can help prevent pain and fatigue.
Prismatic glasses come in different types and sizes. Some of them can be worn on regular glasses, while others can be worn in the form of special frames. Some models have adjustable prism length and angle, which allows you to customize them to the individual needs of the user.
Although prismatic glasses are a fairly specific product that may not be suitable for everyone, they can be beneficial for people who suffer from limited mobility or vision problems. If you think prism glasses might help you, discuss this with your doctor or optician. They will be able to recommend the right model that will best suit your needs.
