When no protection is needed, the frame 11 can be rotated to adjust the angle so that the second magnetic block 13 and the first magnetic block 14 are aligned with each other. A magnetic block 7 is magnetically attracted to each other, thereby stabilizing the frame 11. When the side of the eyes needs to be protected from the sun, the two handles 15 can be pulled to slide the two protective plates 14, and the positions of the two protective plates 14 can be adjusted to provide sun protection on the sides of the eyes. When the upper part of the eyes needs to be protected from the sun, the two handles 15 can be pulled to make the two sliding columns 23 slide in the two arc-shaped sliding grooves 22 respectively, driving the two mounting plates 17 and the two protective plates 14 to move, adjusting the two mounting plates 17 to a suitable position, and then adjusting the two protective plates 14.
