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 Beecher Mirage was developed by the late Dr. Beecher, from the University of Chicago. | ||
| Our practice has prescribed over 1200 Beecher Mirage systems. The most common vision problem has been macular degeneration. | ||

Today we have a group of Beecher products to help many degrees of vision loss at near and far. | |

The systems weigh about 3.5 ounces and are easily focused for distances from about seven 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. | |
| The most common uses of the Beecher Mirage are television viewing, viewing religious services, viewing sports events and driving. | ||
