Blindness is the condition of lacking visual perception due to physiological or neurological factors. Various scales have been developed to describe the extent of vision loss and define blindness. Total blindness is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for "no light perception."Blindness is frequently used to describe severe visual impairment with residual vision. Those described as having only light perception have no more sight than the ability to tell light from dark and the general direction of a light source.
It’s rather difficult to imagine a video game for the blind, seeing they can’t actually see, but what people should loose sight of is that the other four senses are still there, and they’re quite sharper. A group of researchers at the Department of Ophthalmology at Massachusetts Eye and Ear Infirmary and Harvard Medical School have [...]
In the culmination of 15 years worth of painstaking research work related to retina implants, scientists from Germany and Hungary have for the first time demonstrated that a light sensitive electronic chip, implanted under the retina, can restore useful vision in patients blind from hereditary retinal degeneration. As part of the research, nine persons previously completely [...]
Remarkably, researchers University of California, Berkeley have discovered that a chemical called AAQ can temporarily restore the vision in blind mice. The find might help people suffering from inherited genetic blindness or age-related macular degeneration, and bring back light into their world. The process isn’t quite as easy as applying eye drops, but it’s a whole lot less intrusive [...]
One of the most sophisticated parts of a robot is its navigation system, why requires precise sensing and processing of the information, if an anthropomorphic robot is to walk around a house safely or a rover trek through the rocky wastelands of Mars, for instance. Billions have been dedicated to this field, and naturally technological [...]
Researchers have managed to restore light perception to mice through gene therapy, by inserting algae genes into the retina. The treatment has succeeded in restoring the ability to sense light and dark to blind mice, and clinical trials in humans could begin in as little as two years. “The idea is to develop a treatment [...]
