title: New instruments and products. Spectacle-mounted telescopic lenses for children.
abstract: Telescopic aids for children have received little attention in the ophthalmic literature. What has been written is anecdotal and stresses the negative aspects of mobility with spectacle mounted aids. The benefits of a telescopic system that also maintains the patient's mobility are presented in this article. Mounted high in a spectacle carrier lens and with a 10 degrees upward inclination the telescope is "out of the way" while the patient is moving about. However, instant availability is obtained by the patient depressing his chin slightly to align his visual axis with the scope. Forty of 167 legally blind students at the Missouri School for the Blind were fitted with these aids. The objective and subjective results were excellent. Students with albinism and aniridia seem well suited for this type of aid.
