A new pair of goggles that can be used to play Tetris games can also treat a common eye problem according to the British researchers who have developed the gadget.
The gaming goggles has been developed by researchers from Glasgow Caledonian University who say that it can also treat amblyopia, or lazy eye, which affects around 4 percent of children. Patients suffering from amblyopia can focus better through one eye compared to the other and often have to wear a patch on the affected eye.
The new goggles developed by the researchers works by feeding a clearer picture into the affected eye. The researchers said that they found marked improvement among children with amblyopia in just one week after they were made to play Tetris for one hour every day.
"By forcing, in a way, the child to use both eyes the brain becomes aware of the image in the lazy eye. It's as if these cells, which were once dormant, have reactivated and regenerated", lead researcher Dr Anita Simmers said.
