The invention discloses a pair of glasses provided with lenses easy to dismount and mount. The glasses comprise a glasses frame, wherein glasses frame rings, nose pads and temples which are in bilaterally symmetric distribution are arranged on the glasses frame; an annular groove is formed in the center of an inner ring of each glasses frame ring, two sides of the annular groove are the outer sidewall and the inner side wall, an inner side wall bulge is integrally formed on the edge, away from the annular groove, of the inner side wall, a groove is formed in one end, close to the corresponding temple, of the inner side wall, the middle end of the groove coincides with the center line of the annular groove, and two tail ends of the groove coincide with the edge line of the inner side wallbulge. With the adoption of optimized design of the structure, the lenses are simple and fast to dismount and are dismounted and replaced by users conveniently and autonomously, so that use experienceis greatly improved, further, limitation to the glasses frame structure is small, and the lenses are suitable for multiple types of frames; meanwhile, the two glasses frame rings both adopt axial symmetry type design, therefore, the two lenses can be exchanged in the two glasses frame rings, the lens configuration difficulty is reduced, and the use cost of the users is reduced.
