Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears

Advanced Intelligent Systems, EarlyView.
The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.

Aging and Color Vision: A Model Using the Farnsworth‐MUNSELL 100‐Hue Test

Color Research &Application, EarlyView.
ABSTRACT Introduction This study examined the theoretical changes in the FM100 Hue scores induced by age‐related changes in the ocular media transmittance. These changes were analyzed with and without a von Kries‐type chromatic adaptation to determine the role of this adaptation process on age‐related changes in hue discrimination.
