More research needs to be conducted into the viability of augmented reality contact lenses before the products are rolled out on a widespread basis, it has been claimed.
Karen Sparrow, optometrist and education advisor for the Association of Optometrists, said that the augmented reality contact lenses may eventually have advantages over ordinary contact lenses, but this is a long way off.
One example of the new technology is the Google glasses, which have been highly publicised over the last few weeks and enable people to see a computer display at the same time as walking down the street.
However, there could be drawbacks to this type of technology, which may become evident, she noted.
"Now obviously, something that distracts you from what you are doing might be a problem. You probably wouldn't want it to be working if you were crossing the road for instance," Ms Sparrow said.
This technology projects an image out in front of people and displays what they would see if they were looking at a computer screen.
However, in terms of augmented vision or bionic vision, it depends on somebody's own pair of eyes and how well they might be able to see.
"It may be that they manufacture eye wear that can be glasses or contact lenses that will enable you to see in this way but there needs to be lots more science and research involved to see how useful that would be in people's daily lives," the expert added.
It comes after Innovega recently announced the development of the iOptik lens, which will enable wearers to see a superimposed, virtual reality and could eventually be rolled out worldwide.
In addition, the contact lens will also be able to improve users' vision as they look at the real world around them.
