Micro Plastic Lens Improves Vision

Precision micro plastic components, aluminum mirrors and polarizing film combine in a U.S.-funded research project to improve vision. The telescopic contact lens magnifies 2.8 times.TelescopicContactLens_1

“We think these lenses hold a lot of promise for low vision and age‐related macular degeneration (AMD),” says Eric Tremblay, an EPFL researcher whose collaborators include Joseph E. Ford, a researcher at the University of California, San Diego, and others at Paragon Vision Sciences, Innovega, Pacific Sciences and Engineering, and Rockwell Collins. EPFL stands for Ecole Polytechnique Fédérale de Lausanne in Switzerland.

The invention incorporates a very thin reflective telescope inside a 1.55 mm thick lens. Small mirrors within bounce light around, expanding the perceived size of objects and magnifying the view, so it’s like looking through low magnification binoculars.

The most recent iteration incorporates air channels that are 0.1mm wide to allow oxygen to flow under the normally impermeable optical structures to reach the cornea.
