The present embodiment has the same dimming effect as that of embodiment 1, and also has the characteristics of fast dimming speed and wide dimming range.
In this embodiment, the first liquid crystal layer 104 is made of TN liquid crystal (twisted nematic liquid crystal) material, for example. TN liquid crystal molecules are in a 90 ° or nearly 90 ° twisted state in an electroless or low-power state, and have optical activity, and incident light forms polarized light after passing through the first polarizing layer 400, and the polarized light is rotated by the twisted liquid crystal when passing through the first liquid crystal layer 104, and when the light absorption axis directions of the second polarizing layer 500 and the first polarizing layer 400 are perpendicular to each other, the rotated polarized light can smoothly pass through the second polarizing layer 500, and at this time, the light and dark adjustable lens has high light transmittance.

The Bluetooth control device is added in the control device 800, and mainly aims to enable the myopia glasses to be connected with the mobile phone through the Bluetooth control device in a Bluetooth mode, and dimming control can be performed on the myopia glasses through the mobile phone after connection is completed.
