[Prescription of special optical aids for visual defects. II].
In 1993-1995 the authors prescribed in the Institute for the Treatment of Ophthalmological Defects and the Second Ophthalmological Clinic optic aids for 795 patients with impaired eyesight and evaluated their functional effectiveness. Optic aids for far distance were prescribed to 325 patients. Their mean natural vision (or with common correction) was 4.5/60. With the optic aid the mean vision improved to 6/15-12. Aids for short distance were prescribed to 758 patients. Their mean natural vision or with common correction was J. No 15; with the use of the prescribed aid it improved to J. No 5.
