Monocular observation: we recommend using only one eye of the binocular magnifier to observe the object, as the focusing will fail when using both eyepieces at the same time. You can use two barrels alternately to eliminate visual fatigue and improve your work effectively. Note: This magnifying glass is suitable for close operation, please observe the object close to the target.4. Removable: The stand and headband are replaceable, both can be worn safely and reduce fatigue during long-term use. And the adjustable magnifying glass bracket can be rotated up and down, and can be rotated to the desired position to ensure that the eyeball is in the middle position, and the details can be seen more clearly.
