Telescopic systems are ideal for enlarging distant objects. There are two types of systems, Galilean and Keplerian systems. When combined with front caps, these telescopic systems also enable near vision, e.g. for reading, viewing photos or craftwork. Telescopic systems are available in a wide range of magnifications. They enable people with extremely low vision caused by eye disorders to regain their ability to read, watch TV or find their way around outdoors.
