Increased sports activity and exposure to ultraviolet rays means an increased risk to your child’s eyes, say experts at The Vision Center at Childrens Hospital Los Angeles.

New research shows that children’s eyes can be damaged from sun exposure like their skin. This damage may lead to increased risk of developing diseases including cataracts or macular degeneration as adults.

A Swedish inventor has unveiled a solar-powered water purifier that could provide billions of the world’s poorest people with access to clean and disease-free drinking water [video].

The device, called the Solvatten, (Swedish for ’sun water’), looks much the same as a standard jerrycan and can be filled with up to ten liters of water, opened out, and left in the sun. A simple indicator shows either a red or green face to let users know when the water is safe to drink (typically after 3-4 hours), thus avoiding the risk of contracting water-borne diseases.

Over one billion people - 18% of the world’s population - lack access to safe drinking water worldwide. Only 56% of Africa’s 800 million population have access to clean water. About 700 million people in 43 countries are affected by water scarcity, according to the UN.

In another few years - in 2025 to be precise - the number could swell to 3 billion driving back gains in the fight against poverty and under-development, otherwise known as the Millennium Development Goals (MDGs).

For many people around the world, safe drinking water is a scarce resource and out of necessity, they resort to what’s available - polluted water.

But contaminated water isn’t just dirty—it’s deadly. Some 1.8 million people die every year of diseases like cholera, caused by poor sanitation. Tens of millions of others are seriously sickened by a host of water-related ailments—many of which are easily preventable.
