Should myopic students wear eyeglasses?―A regression-discontinuity analysis

Applied Economics Letters, 2022
Despite the high prevalence of myopia among school-age children in China, many myopic students are reluctant to wear eyeglasses. This study estimates the effects of wearing eyeglasses on myopic students’ academic performance, using data from a large ...

Standards of Eyeglasses

Medical Care, 1973
There are formal and informal standards for lenses, frames, and the fabrication of eyeglasses. We review here the context and analyze the applicability of these standards. The experiences of the New York City Medicaid Program in establishing and overseeing its ophthalmic standards is presented. The general disorganized state of ophthalmic standards and

Mobile. Egocentric Human Body Motion Reconstruction Using Only Eyeglasses-mounted Cameras and a Few Body-worn Inertial Sensors

IEEE Conference on Virtual Reality and 3D User Interfaces, 2021
We envision a convenient telepresence system available to users anywhere, anytime. Such a system requires displays and sensors embedded in commonly worn items such as eyeglasses, wristwatches, and shoes.

Correcting Presbyopia With Autofocusing Liquid-Lens Eyeglasses

IEEE Transactions on Biomedical Engineering, 2021
Objective: Presbyopia, an age-related ocular disorder, is characterized by the loss in the accommodative abilities of the human eye. Conventional methods of correcting presbyopia divide the field of view, thereby resulting in significant vision ...

Perovskite‐Based Smart Eyeglasses as Noncontact Human–Computer Interaction

Advances in Materials
More than 70% of human information comes from vision. The eye is one of the most attractive sensing sites to collect biological parameters. However, it is urgent to develop a cost‐effective and easy‐to‐use approach to monitor eyeball information in a ...

Computational Phase-Modulated Eyeglasses

IEEE Transactions on Visualization and Computer Graphics, 2021
We present computational phase-modulated eyeglasses, a see-through optical system that modulates the view of the user using phase-only spatial light modulators (PSLM). A PSLM is a programmable reflective device that can selectively retardate, or delay, the incoming light rays. As a result, a PSLM works as a computational dynamic lens device.

Generative Landmarks Guided Eyeglasses Removal 3D Face Reconstruction

arXiv.org
Single-view 3D face reconstruction is a fundamental Computer Vision problem of extraordinary difficulty. Current systems often assume the input is unobstructed faces which makes their method not suitable for in-the-wild conditions.

Lab-on-Eyeglasses to Monitor Kidneys and Strengthen Vulnerable Populations in Pandemics: Machine Learning in Predicting Serum Creatinine Using Tear Creatinine.

Analytical Chemistry, 2021
The serum creatinine level is commonly recognized as a measure of glomerular filtration rate (GFR) and is defined as an indicator of overall renal health. A typical procedure in determining kidney performance is venipuncture to obtain serum creatinine in
