Contact lens with built-in telescope could help people with blinding disease
Scientists are developing smart contact lenses embedded with miniscule 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 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. AMD causes the loss of central vision due to gradual damage to the eye's retina and there are few options for cure or treatment. The lenses have only been trialed on a handful of humans to test for comfort, with the majority of research to date performed in the lab using a model chemical eye. But more human trials are on the cards with the eventual goal of daily wearable contacts to aid the visually impaired.
