Contact lenses that can monitor your health as well as correct your eyesight aren't science fiction, but an efficient manufacturing method has remained elusive. Until now. Researchers have reported developing a new manufacturing method to produce the lenses, solar cells and other three-dimensional curvy electronics.

Read moreThis study aimed to propose a new method for a bi-objective optimization. Ten student participants used a touch screen at 3 different installation heights, 3 tilt angles and with 3 button sizes. The joint angles, while using a touch screen, were measured to estimate physical workload. With the subjective screen visibility determined, the Pareto optimal solution showed ranges of 1124-1251 mm height and 44.4-67.9° tilt angle for the optimal installation of touch screens.
