The future of contact lenses is to wear them inside the eye, according to a scientist.
Daily contact lenses - currently the choice of millions of people thanks to their convenience and hygiene benefits - could become redundant with new technological advances.
Scientists are trying to develop flexible lenses that respond to movement of the eye"s muscles.
Everyone over 45 would benefit because it means they will be able to see distance and near absolutely naturally.
"It is the true definition of a bionic eye."
However, the thought of eye surgery may not be for everyone and contact lenses are a comfortable option for many people.
In addition to this, the price of contact lenses over the internet means they are convenient and cheap to order and have delivered.
