Problems solved by technology

Because the oncoming vehicle has high beam lights on, the driver's eyes will be irradiated by the opposite light and cannot see the road ahead. of novice drivers don't know how to change the lights when meeting cars, which caused a traffic accident

[0003] In the prior art, there is a kind of glasses that can help the driver block the strong light on the opposite side, but when there is no vehicle on the other side, wearing glasses will make the eyes darker, which is not conducive to driving

And wearing it for a long time will deform the eye sockets and affect the image
