It also predicts further increases in the number of cases by if treatment is not improved—with almost million cases of blindness and million people with moderate to severe vision impairment.

Computer Science researchers at Queen Mary University will use the psychological findings from these tests to develop new computer software applications that aim to develop new software - supporting people who are visually impaired in their work and leisure activities.
The new technology will be tested at the University of Bath for functionality and usability to gauge its impact on the ability of blind people to collaborate with sighted people. The project brings the disciplines of psychology, computer science and engineering together in new ways that aim to influence the individual fields, but ultimately allow for a bright future for those individuals who are becoming visually impaired and enable them to feel they have a full, interactive place with the visual world.
The vOICe sensory substitution device is a revolutionary tool that helps blind people use sounds to build an image in their minds of the things around them. Tests using the device found that, even without any training, the best performances exceeded the level of visual performance of the current invasive technique for vision restoration, such as stem cell implants and retinal prostheses. Although the use of stem cells might improve to provide the literal sensation of sight with time, the affordable and non-invasive nature of the vOICe provides another option.
As well as an alternative to invasive techniques, sensory substitution devices might be best used alongside them to train the brain to see again, or even for the first time. University of Bath. Analysis of data from countries suggests there are more than million people with moderate to severe vision impairment. That figure is expected to rise to more than million by He said it also limited people's educational and economic opportunities. The worst affected areas for visual impairment are in South and East Asia.
Parts of sub-Saharan Africa also have particularly high rates. The study calls for better investment in treatments, such as cataract surgery, and ensuring people have access to appropriate vision-correcting glasses. Prof Rupert Bourne said: "Interventions provide some of the largest returns on investment.
