With the technological advancements, medical science is able to solve gravest of problems plaguing the human race. The innovations made in this field are innovative and promising, working towards making our every-day lives easier. The bionic eye is one such invention that is proving to be a blessing for those with no or low eyesight.
It is basically an experimental visual device that can help in the restoration of functional vision. The aim behind this innovation is to reconstruct the optic signals for people who are blind or are experiencing an acute eye disease such as retinitis pigmentosa (which is a rare genetic disorder in which each cell bordered in the retina collapses, resulting in the depletion of peripheral vision). With the help of the bionic eye, one can take care of diminishing vision as well.
The entire procedure is based on an electronic system that includes an image sensor, microprocessors, receivers, retinal chips and radio transmitters. This artificial intelligence also includes 3,500 micro photodiodes, which are placed in the back of the retina. The working of this artificial eye can be compared to that of the human eye.
It functions with the help of an apparatus, which is used by the person with no eyesight. Similar to the human eye, it also receives an image from the camera lens fixed in the instrument. This image is then sent to the microprocessor, that reforms the data into an electronic signal. Further, the waves are then transmitted to the brain by the tiny cable of an electrode panel, which enables the mind to decode the signal and recognise the subject.
Unfortunately, with the help of this advancement, we are able to restore lost visions to only an extent. There are limitations attached to it, as this is only helping in developing a blurred vision, a clearer vision seems far. The process of complete revival of the eyesight still has a long way to go. With the progression in a higher number of electrodes, the bionic eye may help in building a more definite, coloured and functional image in future.
