Light-responsive contact lenses developed

UV-protective contact lenses, which darken when exposed to excessive sunlight, have been developed at a laboratory in Singapore.

Eye conditions such as age-related macular degeneration and cataracts are caused by long-term, unprotected exposure to sunlight.

But scientists at the Institute of Bioengineering and Nanotechnology (IBN) in Singapore have developed an answer - the first "photocromic" contact lenses for vision protection.

The innovative lenses adapt to changes in lighting indoors and outdoors – providing the best possible vision without discomfort.

IBN executive director Professor Jackie Ying said: "IBN"s mission is to conduct strategic research that addresses important biomedical problems through novel technology platforms that present major commercial potential."

Professor Ying was named as one of the "one hundred chemical engineers of the modern era" at the American Institute of Chemical Engineers centennial celebrations in 2008.

IBN was established in 2003 as a national research institute under the Agency for Science, Technology and Research, Singapore.
