The difference between the two OptiVISOR models in this collection comes down to magnification power and working distance:

• OptiVISOR DA5 (2x): Offers roughly a 10-inch focal distance, ideal for general close work where you still want room to move your hands and tools.
• OptiVISOR DA10 (3.5x): Provides higher magnification at a shorter working distance, suited to the finest detail — precise instrument work, small-component inspection, and intricate procedures.

Both feature binocular acrylic lenses, which reduce eye strain compared to single-lens loupes by letting both eyes work together, preserving depth perception. If you wear prescription glasses, the OptiVISOR fits comfortably over them.

A common question is how to pick the right power: choose based on how close you can comfortably work. Higher magnification narrows both the field of view and the focal distance, so the DA5 is the more versatile everyday choice, while the DA10 is for when the DA5 simply isn't strong enough.
