Abstract: An optical magnifying device is adapted for reflecting a magnified image of an object to eyes of a user, and includes a support unit, a frame unit mounted to the support unit, and a mirror unit mounted to the frame unit. The frame unit includes two spaced apart support arms and a mounting arm connected between the support arms. The mirror unit includes an objective mirror set mounted to the support arms, and an ocular mirror set detachably mounted to the mounting arm and spaced apart from the objective mirror set. The ocular mirror set has a first positioning member detachably connected to the mounting arm. The mirror unit is configured to form an optical path forming the magnified image of the object and adapted to reflect the same to the eyes by the ocular mirror set.

Abstract: A head-mounted optical magnifying device is adapted to be worn on a head of a user and for reflecting a magnified image of an object to eyes of the user. The head-mounted optical magnifying device includes a head frame unit, a mirror frame unit mounted to the head frame unit and including two support arms, a mirror unit, and a counterweight unit. The mirror unit is mounted to the mirror frame unit, includes objective and ocular mirror sets, and is configured to form an optical path extending from the object toward and reflected by the objective mirror set, and then extending toward and reflected by the ocular mirror set to the eyes of the user. The counterweight unit includes a head counterweight slat having a proximal end mounted to the head frame unit and a distal segment opposite to the proximal end.
