3x Magnifier (O50mm)

A 3x magnifier with a lens diameter of 50mm refers to a handheld optical device that provides a magnification of three times (3x) and has a lens diameter of 50mm. This means that when you look through the magnifier, objects will appear three times larger than their actual size, and the lens has a diameter of 50mm.

The 3x magnification indicates that the magnifier enlarges the viewed objects three times. For example, if an object is normally 10mm in size, when viewed through the magnifier, it will appear as if it is 30mm in size.

The lens diameter of 50mm specifies the size of the magnifier’s lens. A larger lens diameter allows for a wider field of view and more comfortable viewing experience, as it allows more light to enter the lens.
