Dr. Bailey Shen and\u00a0Dr. Shizuo Mukai from the USA have developed a prototype camera unit that can be used by opticians to take photos of your retina. Normally, pupil-dilating eyedrops are required to do this, causing blurriness and headaches afterwards. By using a combination of light sources to first of all focus on the retina and then to take the actual picture, the eyedrops aren’t necessary. The camera’s total cost is approximately $185, a fraction of professional units.\u00a0A ScienceDaily article is available to read here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
