For many decades, experts from around the world have been improving my skills in making eye prostheses. The result is not forced to wait: modern prostheses are almost impossible to distinguish from a real living organ with only a reservation – this is really only for daylight. In the evening, they are given a pupil. However, scientists from the UK have made a breakthrough in this area, creating an electronic prosthesis.
Despite the skill of the work of specialists engaged in the manufacture of eye prostheses, all of them were united by one very important drawback – their unnecessority is given out by the pupil: unlike a living eye, a “painted” pupil on a glass cornea of the prosthesis with a change in the intensity of lighting cannot narrow and expand.
If we are talking about an elderly person, then for him this difference is completely insignificant, but for young people, especially girls, this is a real problem. After all, after the physical and psychological trauma, I want to look normally at a disco, party or romantic date in the dark,.
Now they have such an opportunity provided by scientists from the University of Trent in the English city of Nottingham (Nottingham Trent University). For such people, they offer an invention created as a result of university research, which were conducted together with specialists from the company for the manufacture of eye prostheses John Pacey-Lowrie Ocular Prosthetics. This is a prosthesis that is crammed with electronics and eats from a very small battery.
The invented prosthesis can determine the degree of change in illumination thanks to a tiny sensor. Depending on this indicator, it passes through the pupil electric current. For this, an “artificial” pupil was made from a special material that allows you to do this.
So, when it becomes darker around a person, the sensor gives a signal about the need to increase the current strength. As a result, the pupil of the prosthesis expands similarly to how the real pupil of the human eye does it.
In more vivid lighting, the current stops passing through the pupil, so it returns to its usual narrowed state, characteristic of a living pupil.
Such an invention of British scientists will make the lives of many people who have lost their eyes for certain reasons, more normal, and will also help to overcome the psychological problem much faster.
