While eyeglasses have improved the lives of millions of people, many wearers are painfully aware of how weird glasses can make their eyes look. The eyes of near-sighted wearers appear smaller through the lens, while the eyes of far-sighted wearers appear larger.
The problem is “the traditional process of trying on and picking new eyeglasses in a brick-and-mortar shop has a significant shortcoming: eyeglasses on the display are equipped with demo lenses that have zero corrective power, and thus refraction does not deform the eyes,” write Qian Zhang of Nanyang Technological University in Singapore and other researchers in “A Virtual Try-On System for Prescription Eyeglasses,” published in the July/August 2017 issue of IEEE Computer Graphics & Applications.
Zhang and her team have developed a system to give users a more realistic experience, a virtual try-on system for prescription eyeglasses modifies an input video and virtually inserts prescription eyeglasses, producing an output similar to a virtual mirror.
The proposed system generates a 3D representation of the corrective lenses mounted into the eyeglasses frame, giving wearers an accurate picture of how the glasses make them look.
Better than other virtual try-on systems, this approach simulates the refraction effects due to the corrective lens and takes into account reflections and shading, allowing wearers to make more informed purchasing decisions.
