Title:
VISION PROTECTION DEVICE FOR ELECTRONIC APPARATUS HAVING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/143072
Kind Code:
A1
Abstract:
A vision protection device for an electronic apparatus having a display device comprises: micropower laser sources (2, 2') provided at the periphery or back of a display screen (5) of an electronic apparatus; and a control circuit (1') provided inside the electronic apparatus to cyclically control operation of the micropower laser sources. The control circuit controls the micropower laser sources to irradiate the eyes with micropower laser beams, such that the micropower laser energy absorbed by the eyeballs facilitates blood circulation in the eyeballs and the lens, thereby enhancing automatic accommodation ability of the lens. The invention can resolve the issue in which the accommodation ability of the lens deteriorates when the eyes focus on the same screen for a long time, thereby enhancing the health of the eyes, preventing nearsightedness, improving vision, and facilitating correction of nearsightedness.
