Description

Spectacle-frame convenient to adjust

Technical Field

The utility model relates to a glasses technique especially indicates a spectacle-frame convenient to adjust.

Background

Spectacles are lens pieces embedded in a frame that are worn in front of the eyes to improve vision, protect the eyes, or for decorative purposes. Lenses can correct a variety of vision problems including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia, and the like.

The glasses include myopia glasses, hyperopia glasses, presbyopic glasses, astigmatic glasses, plano glasses, computer goggles, swimming goggles, night vision goggles, electronic competition game goggles, electronic competition goggles, sunglasses, toy glasses and sunglasses 15. There are also special glasses for watching 3D stereoscopic images or virtual real images. Other types of eyewear include goggles, sunglasses, swimming goggles, etc., which provide various types of protection to the eyes. Modern spectacles are usually provided with a nose pad in the middle of the lens and soft pads at the positions where the left and right arms rest on the ears. People who like beauty or are not used to wear glasses can choose to correct vision with contact lenses. Although contact lenses and laser vision correction operations are more and more popular in recent years, the wearing of the lenses is still a safe and effective vision correction tool, but the size of the head of most people is a problem, so that the comfort level of a user is determined by the size of the glasses frame, and the small glasses frame enables the head of the user to be tightened for a long time, so that marks are left, and the user feels uncomfortable.
