Research into digital contact lenses continues as scientists develop and regularly report new inventions that can eventually lead to the availability of contact lenses capable of displaying video images. Recently, they have come up with a material that could revolutionise display technology and make digital contacts a reality quite soon.
The researchers, working at Oxford University, adapted a material used in the production of DVDs. In an article published in Nature, they claim that their invention can introduce a new generation of displays, which will be extremely thin and light, and which will consume much less power than those used today. In addition, these displays will be possible to place on transparent surfaces, such as contact lenses or window panes.
The technology is based on the fact that some substances change their structure with temperature. This phenomenon is already used in many areas, but for the first time to make a surface change colour, which is necessary to display images.
Interestingly, the researchers’ first experiments were very successful and they made great progress in a very short time. As a result, they are confident that their invention will be used commercially within a few years.
