glasses

The present invention relates to a type of eyeglasses, and more particularly to a pair of eyeglasses that can be adjusted to match the size of a user's head.

Early glasses are usually designed with a pair of temples on the left and right sides of a lens unit. By attaching the lens unit to the bridge of the nose and the hooks of the temples on the ears, it is possible to wear glasses. purpose. However, since each user's head size is different, for example, the distance between the bridge of the nose and the ear is different, each of the temples has a fixed length, and the distance between the two temples is fixed and cannot be adjusted, so the glasses are worn. If the temples are not properly spaced from each other, it will cause discomfort in wearing.

Referring to Fig. 1, in order to overcome the aforementioned problems, Taiwan Patent No. M358315 discloses a lens that can adjust its structure in accordance with the size of a user's head. The lens includes a lens body 91, two adjustment blocks 92, and two mirrors. Feet 93. The spectacles body 91 has two engaging portions 911 on opposite sides.
