Graphene Oxide Thin Film Eyeglasses

 

Project Introduction

Traditional eyewear lenses rely on a series of grinding, polishing and other deep processing procedures in the glass lens to form a concave or convex lens, and then form the required degree to achieve correction of myopia or hyperopia goals. Although the processing of glasses have a fixed equipment, but the processing time is long, and because of the different processing experience, the processing effect of a certain degree of uncertainty. In addition, for more serious myopia or hyperopia, the curvature of the lens caused by increased lens thickness. While the manufacture of ultra-thin lenses will greatly increase the cost and require a higher process.

 

The recent development of the graphene film of graphene (http://www.nature.com/ncomms/2015/150922/ncomms9433/full/ncomms9433.html) has provided the possibility of a technological revolution for ultra-thin glasses. The graphene film is subjected to laser pattern processing on a very thin (~ several tens of nanometer) oxide graphene film to achieve the design of a convex lens or a concave lens. This thin film lens is expected to break the traditional lens to rely on geometric curvature for wavefront shaping needs. Depending on the laser pattern, the wavefront is adjusted to form the coherence of the light (real focus hyperopia correction) or coherent cancellation (virtual focal myopia correction).

 

Project features: to remove the expensive vacuum coating process, innovation and traditional glasses processing technology, a significant reduction in production costs. The use of new graphene material to achieve multi - functional glasses.
