Recent advances in smart contact lenses can assist biomedical engineers to realize medical applications and vision imaging for augmented reality with wireless communication systems. Previous research on smart contact lenses ...
Our vision can be damaged or lost by damage to the retina—a sensory membrane lining the back of the eye that senses light, converting the image formed into electrochemical neuronal signals—resulting from two classes of ...
Making the most of the low light in the muddy rivers where it swims, the elephant nose fish survives by being able to spot predators amongst the muck with a uniquely shaped retina, the part of the eye that captures light. ...
