Micro Telescopic Lenses for Macular Degeneration Patients

3/24/15   Researchers from the Ecole Polytechnique Federale de Lausanne in Switzerland have improved on their micro telescopic lenses that were first released in 2013. The latest prototype was unveiled at the American Association for the Advancement of Science annual meeting.
This contact lens has micro telescopic lenses that respond to the blink of an eye and can zoom in on objects with up to 2.8 magnification.
The lenses were first developed to enhance soldiers vision capabilities in the field, the newest prototype is being promoted as a possible visual aid for macular degeneration sufferers.

This new prototype contact lens is just 1.55mm thick. Unlike soft-lens contacts, the telescoping lenses are placed on the sclera (white part of the eye) using numerous precison micro machined plastic components, micro aluminum mirrors and polarizing film. There are also micro sized air channels across the structure of the lens to provideadequate flow of oxygen.

Obtaining a balance between contact function, cost and eye comfort is always a hurdle when researching new and improved eyewear. MES has worked on many micro ophthalmic projects over the years. Anyone who wears contact lenses knows it is extremely uncomfortable and irritating to the eye to have even a tiny dust-speck sized piece of dirt on surface of your lens. For this reason surface finish and the blending of parting lines, spherical radii, and matching cores & cavities are the key to creating these challenging lenses.
