Video game fans - this one's for you.
Doctors in Glasgow have developed a new game that might be good for your health.
The programme has been designed to help children with a problem called a lazy eye, which is when the vision in one eye doesn't develop properly.
By playing the game the brain is made to work the lazy eye harder, helping it to work correctly.
Lazy eyes are normally treated by patients having to wear an eye patch over their stronger eye and affect about 2 in every 100 children in the UK.
The researchers in Scotland have had great results so far with children who played the game daily having better sight after just ten days.
They hope that the technology might be able to be used to help others with eye problems.
