Donegan OptiVisor head loupes offer the highest quality hands free viewing for close up magnification. 3.5X optical quality replaceable glass lens
The highest quality optical glass lenses are mounted into a frame on a comfortable headband that can be tilted out of the way when magnification is not needed. Designed for close work, either reading, writing or crafting projects. They can be worn over glasses or alone. We offer them in 3 strengths. Note that the stronger the magnifier, the closer the reading matter must be held to be in focus. Working distances are: 1.75X - 14 inches, 2.50X - 8 inches, 3.5X - 4 inches.
