From the medical perspective
The artificial eye serves the orbit as protection against environmental influences and, in doing so, prevents possible chronic infections.
The special glass used for ocular prostheses is the best possible material in this context. Its processing gives the artificial eye a homogeneous, fire-polished surface which is optimally moistened by the tear fluid. This rules out any form of allergic reaction and ensures excellent biological compatibility.
The optimal fit of the artificial eye also prevents any shrinkage of the eye socket.
An optimally fitting ocular prosthesis is particularly important where children are concerned. This is because the absence of an eyeball would hinder the eye socket’s growth – the inevitable consequence of which would be asymmetries in the facial area.
Besides the medical function, the artificial eye also has a cosmetic and thus a psychological function.
