Disclosed is a high-tension thread fastening structure for an eyeglasses frame having a lens held by stretching a length of high-tension thread around the lower sector of the lens to push the lens against the upper sector of rim. The length of high-tension thread has a single knot formed at each end, each knot being caught by each end of the upper sector of rim, and being terminated with a spherical end, thereby preventing the loosening or unbinding of the fastening. Alternatively the length of high-tension thread has first and second knots formed at each end, the first knot being caught by each end of the upper sector of rim, thereby preventing the loosening or unbinding of the fastening by using the second knot as a backup for the first knot.
