Canadian doctors say they have found an inventive way to treat lazy eye — playing the Tetris video game.
An estimated one in 50 children has lazy eye, known medically as amblyopia.
Normally, the treatment is to cover the good eye with a patch to make the weak one work harder.
Robert Hess of McGill University set out to investigate whether a different approach might work.
Armed with a special pair of video goggles they set up an experiment that would make both eyes work as a team.
Nine volunteers with amblyopia were asked to wear the goggles for an hour a day over the two weeks while playing Tetris, the falling building block video game.
The goggles allowed one eye to see only the falling objects, while the other eye could see only the blocks that accumulate on the ground in the game.
Another group of nine volunteers with amblyopia wore similar goggles but had their good eye covered, and watched the whole game through only their lazy eye.
At the end of the two weeks, the group who used both eyes had more improvement in their vision than the patched group.
The researchers then let the patched group have a go at using the goggles with both eyes uncovered. Their vision then improved significantly.
