Smart spectacles capable of automatically adjusting transparency of lenses according to ambient light intensity

Abstract

The invention discloses a pair of smart spectacles capable of automatically adjusting the transparency of lenses according to the ambient light intensity. The smart spectacles comprise a spectacle rack, left lens, a right lens, a control switch, a left film solar cell and energy storage device, a right film solar cell and energy storage device, an ambient light sensor an a control chip, wherein the left lens and the right lens are respectively embedded into two spectacle frame parts, and are divided into three layers, namely a first lens layer, a liquid crystal molecule interlayer and a second lens layer from outside to inside. The smart spectacles are capable of automatically adjusting the transparency of the lenses according to the intensity of ambient light to adapt with the illumination comfort level of human eyes; the ambient light sensor is used for converting the ambient light around the eyes into electric signals in a working state, treating by virtue of the control chip, and then outputting control voltage to the liquid crystal molecule layer of each lens interlayer. The light transmittance of each liquid crystal molecule layer is changed by changing the polarization state of liquid crystal molecules and combining a specific ambient light polarization state, so that continuous and automatic adjustment of the light transmittance of the lens adapting with the ambient light intensity is realized.

Description

technical field [0001] The present invention relates to smart glasses. The glasses can sense changes in the light intensity around the wearer, and after calculation by the processing chip, the transparency of the lens will be automatically adjusted accordingly, so that the light intensity received by the wearer's eyes is always at a comfortable intensity value, enhancing the wearing experience. The invention has a wide range of user groups: it can be applied to people who wear vision correction glasses such as myopia and hyperopia, and can also be used as ordinary sunglasses for people who do not need vision correction. At the same time, it can be applied to various complex lighting environments such as indoors, outdoors, strong sunlight or cloudy environments. Background technique [0002] Sunglasses are the necessities of life under strong light conditions such as summer. However, the light transmittance of ordinary sunglasses is usually fixed, and the transparency canno...
