An eyeglasses lens-installing apparatus includes a lens. A substantially elliptical through-hole is formed in the vicinity of an edge of the lens. A substantially elliptical columnar member disposed on a lens sandwiching part of a connection member is fitted into the through-hole from one main surface side of the lens. The columnar member has a hole formed therein. A screw portion is provided on the inner peripheral surface of the hole of the columnar member. The columnar member is integral with the lens sandwiching part and the lug. A fastener is inserted into the through-hole from the other main surface side of the lens. The fastener includes a fixing part having a male screw portion disposed on the periphery thereof and a head part. The fastener is inserted into the through-hole, with a close-contact member installed on the periphery of the fixing part. At this time, the fixing part of the fastener is screwed on the screw portion of the columnar member. As a result, the fastener and the columnar member are fixed to each other.
