Children's eyesight appears to be getting worse. That's according to a new study - published in the British Journal of Ophthalmology - which also shows that one in three children worldwide is now short sighted or unable to see things in the distance clearly -- and that number's likely to continue rising.

The highest rates are in Asia - 85% of children in Japan -- Paraguay and Uganda had some of the lowest levels of myopia, with the UK, Ireland and the US all at about 15%.
