121
that is disposed frontwardly of the viewing part
111
, that interconnects the end segments
122
,
124
, and that is formed with an engaging tongue
123
which projects rearwardly therefrom and which extends through the mounting hole
114
in the viewing part
11
. The temples
13
are respectively pivoted to the end segments
122
,
124
of the connecting member
120
through two hinges
126
, each of which is formed with a protrusion
127
that is inserted into the retaining recess

,
124
of the lens member
11
and subsequently pulling and bending the intermediate segment
121
of the connecting member
120
to dispose the intermediate segment
121
in front of the viewing part
111
of the lens member
11
and to permit engagement between the tongue
123
and the mounting hole
114
in the viewing part
111
.
The conventional eyeglasses

SUMMARY OF THE INVENTION
Therefore, the object of this invention is to provide a pair of eyeglasses having a lens member and a temple unit that can be assembled to the lens member in a convenient manner so as to overcome the aforesaid disadvantage of the prior art.
According to the present invention, a pair of eyeglasses includes: a curved one-piece lens member having opposite front and rear faces, upper and lower ends, and opposite left and right sides interconnecting the upper and lower ends, the lens member being formed with an arcuate groove that extends between the left and right sides, that is disposed adjacent to the upper end, that is indented inwardly from the front face, and that has two opposite end portions, the lens member being further formed with left and right passages that are respectively disposed rearwardly and that are respectively aligned with the end portions of the arcuate groove, a left retention hole that is disposed between the left passage and the left side of the lens member, and a right retention hole that is disposed between the right passage and the right side of the lens member; and a temple unit including an elongated curved connecting member that has two end segments and an intermediate segment extending between and interconnecting the end segments, and a pair of temples respectively hinged to the end segments. Each of the end segments of the connecting member is formed with an engaging tongue that projects frontwardly therefrom. The end segments of the connecting member extend rearwardly through the end portions of the arcuate groove and the left and right passages in the lens member, respectively, so as to place the intermediate segment in the arcuate groove in the lens member. The engaging tongues of the end segments project frontwardly into and engage the retention holes in the lens member, respectively.
