Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of eyeglass frames, and particularly relates to an eyeglass frame with good adaptability. BACKGROUND

[0002] An eyeglass frame is an important component of an eyeglass, and mainly serves to support an eyeglass lens. An eyeglass frame with a beautiful appearance can also serve an aesthetic function.

[0003] People who wear eyeglasses for a long time will have a deformed nose bridge. The sponge body at the nose wing is pressed for a long time, resulting in a concave shape. In particular, a person with high myopia will have two obvious pits on the nose bridge after taking off the eyeglasses. Therefore, the first selection criterion for people when selecting eyeglasses is to try to be light, so as to minimize the pressure on the nose bridge. However, for a user with high myopia, it is not true that the lighter the eyeglass frame is, the better. Light eyeglass frames generally have a characteristic that the frame is relatively thin. It should be noted that in actual use, three positions need to generate uniform force on the head to maintain the positioning of the eyeglasses on the face. The three positions are the force on the ear bone at the rear ear hook part of the leg, the support force of the nose pad, and the inward clamping force of the leg. If the degree of the eyeglasses is high, the lens will be thick and heavy. If the frame is too light and thin, the eyeglass frame will be 'top-heavy and bottom-light'. At this time, the two force points on the leg will be weakened, which will increase the pressure on the nose bridge. Moreover, people will install clip-type sunglasses on the eyeglasses in use. When watching 3D movies, 3D glasses will also be clipped. This will further cause the eyeglass frame to be top-heavy and bottom-light, and make people feel very uncomfortable in use.
