The development of smart contact lenses has gone to another level – scientists are now embedding the lenses with miniature mirrors that can magnify a person's vision as many as three times. The lenses are 1.55 millimeters thick and in them a reflective telescope is installed.
The telescope consists of filters and mirrors. The idea is that when the light comes into the eye, it is reflected off a series of mirrors which increases the view of any given object. The scientists are hoping to help patients that suffer from the third leading cause of blindness in the world – the age-related macular degeneration (AMD). AMD is responsible for gradually damaging the retina of the eye.
The key improvement is the possibility of magnifying an object when you put on a pair of glasses that come with the lenses. This is a very attractive feature, hold the scientists. The combination of lenses and glasses makes it easier to go about the daily routine and magnify an object when a person wants to see it larger. At the same time the user of lenses is able to have normal peripheral vision and a magnified object in front of them. This is not the case with regular vision aids.
There were, however, downsides to earlier designs – these lenses, namely, lowered the amount of oxygen that reaches the eye. The scientists have bypassed this problem by creating air channels to help the flow of O2 into the eyes.
