A pair of eyeglasses includes an eyeglass frame and a lens unit mounted detachably on the eyeglass frame. The eyeglass frame includes a curved front frame with two downwardly projecting end portions, and two bows. The curved front frame has an engagement groove formed therein, and a retained portion disposed at the middle section of the curved front frame. The engagement groove has two end portions respectively extending into the front surfaces of the downwardly projecting end portions of the curved front frame. The lens unit includes two lenses and a plastic lens rim mounted securely on the lenses. The lens rim has a rib projecting upward from the upper end portion thereof so as to engage the engagement groove. The rib has two lugs projecting respectively and outwardly from two ends thereof and being inserted into the end portions of the engagement groove. A hook is fixed on the lens rim and has a retaining space formed therein so as to retain the retained portion of the curved front frame.
