Abstract Details

Purpose:

To demonstrate the ability of an optical remotely activatable technology, that may fit to glasses and intraocular lens, to achieve multifocality and zooming capability.

Setting:

Bar-Ilan University, Faculty of Engineering, Institute of Nanotechnologies and Advances Materials, Ramat Gan, Israel

Methods:

We designed an optical setup simulating an externally influenced reflective lens. We used a multiple element lens with coating surfaces, on and in the lens, that have tunable reflectivity as they are made from a semiconducting nano-material whose reflectivity can be modified by an external control illumination at a wavelength that is selectively absorbed by the semiconducting coating layer.

Results:

Using this optical setup in laboratory, we were able to achieved tunable multifocality by selectively bringing into focus the reading chart at 30cm (reading distance) or at 80cm (intermediary-computer distance). Zoom capacity was successfully achieved by magnifying the reading chart placed at distance of 3m by a factor 3.

Conclusions:

These promising preliminary results might bring a revolutionary solution to overcome presbyopia symptoms as well as age-macular degeneration visual impairments, with the help of an image magnification externally activated. A new setup to fit a pairs of glasses is currently under development.
