Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

As shown in fig. 1 and 2, the present embodiment discloses a pollen-proof glasses, which includes a protection cover 1 and a frame 2, wherein the protection cover 1 is detachably assembled inside the frame 2, and the protection cover 1 makes up a gap between the frame 2 and the face of a wearer. Picture frame 2 includes left picture frame, right picture frame and connects the bridge of left and right picture frame, and 2 both ends of picture frame are equipped with mirror foot 3, are equipped with lens 4 and nose on picture frame 2 and hold in the palm 5, and lens 4 and nose hold in the palm 5 can with picture frame 2 integrated into one piece or as independent spare part equipment on picture frame 2. The frame 2, the lenses 4, the temples 3 and the nose pads 5 are all common designs in the field of glasses, and the assembling method thereof can be realized by referring to the prior art.

As shown in fig. 2 to 5, the inner sides of the two ends of the frame 2 are respectively provided with a limiting groove 6, the two ends of the protective cover 1 are provided with limiting protrusions 7, and the two limiting protrusions 7 are respectively inserted into the two limiting grooves 6 on the frame 2. The limiting groove 6 and the limiting convex part 7 are in interference fit, the limiting convex part 7 is clamped by the upper inner wall and the lower inner wall of the limiting groove 6, and therefore the position of the protective cover 1 relative to the mirror frame 2 in the vertical direction is determined. The two retaining grooves 6 are preferably arranged oppositely, and the frame 2 and the protective cover 1 are preferably symmetrical structures, so that the pressure on the two sides of the face of the wearer is the same. The frame 2 and the protective cover 1 of the present invention are preferably made of plastic material and preferably have good wear resistance. The protective cover 1 is preferably made of a material having elasticity and can be more tightly attached to the face of the wearer.

As shown in fig. 2 to 5, in order to ensure the assembling stability of the shield 1 and the frame 2, it is preferable that the nose pads 5 integrally formed on the frame 2 are each provided with a groove 8 on a side away from each other, the shield 1 is provided with two opposing stopper portions 9 respectively inserted into the two grooves 8, and when the two stopper portions 9 are inserted into the two grooves 8 to be positioned, the shield 1 is attached to the frame 2. Spacing portion 9 and recess 8 are interference fit, and the front and back terminal surface of spacing portion 9 is pressed from both sides tightly by the inner wall of recess 8, and recess 8 prevents relative picture frame 2 of protection casing 1 to produce the back-and-forth movement with the cooperation of spacing portion 9. Fig. 3 shows a preferred embodiment in which the nose pad 5 is integrally formed with the frame 2. if the nose pad 5 is assembled to the frame 2 as a separate component, the groove 8 may be formed in the frame 2, or the conventional metal bracket of the nose pad 5 may be modified to have a structure capable of blocking the movement of the stopper 9.
