Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.

			Study reveals a revolutionary way to treat eye injuries, prevent blindness New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness - by softening the tissue hosting the stem cells which then helps repair wounds, inside the body.

			What is Lagophthalmos? Lagophthalmos is a condition in which the eyelids do not close completely. This prevents complete closure during blinking as well as during sleep.

	What is Ametropia? Ametropia is defined as an eye disorder due to an error in the refractive power of the eye. In simpler words, the eye is unable to bend light correctly and focus images directly on the retina. This ultimately results in blurred vision.

	What is Iridodonesis? Iridodonesis is a condition in which the iris (coloured part of the eye) vibrates during eye movements. Upon moving the eye rapidly, the iris can appear to ‘dance’, or ‘tremble’ (tremulousness).
