The Beecher
Mirage 4X and 5.5X provide moderate magnification in a lightweight headborne
binocular system. The expanded field of view and brightness of these optical systems make
the Beecher excellent for television viewing by patients with loss from macular
degeneration. The systems weigh about 3.5 ounces and are easily focused for distances from
about six feet to infinity. Patients generally report better appearance of colors in TV
viewing which we believe is due to the brightness of the system. Patients in the range of
about 20/100 to 20/300 may benefit from the 4X system.
