Contact lens with built-in telescope could help people with blinding disease

• Scientists are developing smart contact lenses embedded with minuscule mirrors that can magnify your vision by almost three times.
• The 1.55mm-thick lenses incorporate a thin reflective telescope made of mirrors and filters; when light enters the eye it bounces off the series of mirrors and increases the perceived view of an object or person.
• It is hoped that the lens will improve the sight of people with age-related macular degeneration (AMD) -- the third leading cause of blindness globally.
• A key innovation with the lenses is the added ability to switch between magnified and regular vision through a complementary pair of glasses.
• The battery-powered glasses use LCD technology to watch the movement of the eye and a simple wink can alter their polarization and determine whether light entering is magnified or not.
•  A strategic wink will enable users to keep an eye on their periphery, such as cars approaching them as they cross a street, whilst also being able to zoom in and recognize the faces of those around them.
