A glasses' front frame having a V-shaped groove 5 which receives a locking ledge stripe 1c, having a V-shaped cross section, around a circumference of a lens. There are formed a first frictional biting-into protrusion stripe 6a and a second frictional biting-into protrusion stripe 6b, respectively, on a first inclined bottom surface 5a and a second inclined bottom surface 5b defining the V-shaped groove 5. The first and second frictional biting-into protrusion stripes 6a, 6b extend in a direction in which the glasses' front frame extends, locate near upper edges of the first inclined bottom surface 5a and the second inclined bottom surface 5b defining the V-shaped groove 5, and contact a part of a first inclination bottom surface 1a of the locking ledge 1c of the lens 1 and a part of a second inclination bottom surface 1b thereof.
