Arclight: a device to fight blindness in poorer countries

To detect early signs of blindness, eye doctors use a wide range of sophisticated and expensive equipment like the ophthalmoscope that requires replaceable items like films, bulbs and batteries. Scientists in Britain have developed a much simpler and smaller device called Arclight. It has been designed to make instant diagnostic decisions in poorer countries. Dr Andrew Blaikie of the University of St Andrews in Scotland is the lead researcher of the team who has created the device.
