Rechargeable head magnifier

The GUOUBUO GU-XSB-R223XC-B-N is a rechargeable head-mounted magnifier designed for close work such as watch repair, crafts and jewellery. It provides five interchangeable rectangular acrylic lenses with individual magnifications of 2X, 4X, 6X, 10X and 13X that can be combined up to 23X. The blue frame holds dual LED lights with two brightness levels and independent power buttons for each side.

Switchable binocular frame and lenses

The switchable binocular frame allows single-eye observation to reduce strain during extended use, with a focal length range from .85in to 9.84in. Rectangular lenses give a larger viewing area than round equivalents and store in a protective case. Dual LED illumination offers separate control for left and right lenses, while the rechargeable power supply removes the need for disposable batteries.

Practical limits of high magnification

At the highest 13X setting the optimal focal length is only 1.52in, so the lens must be held very close to the object. Using both eyes simultaneously at high power produces blurring, so the maker recommends single-eye viewing. The fixed set of five lenses means users who need magnification steps outside the 2X to 13X range must look elsewhere.

Questions about this item

What is the highest magnification available with the 13X lens and how close must I hold it to the object?

The 13X rectangular lens provides up to 13X magnification alone and combines with others for 23X total. Its optimal focal length is 1.52 inches, so you must hold it very close to the work.

How does the head-mounted frame fit and what wearing options exist?

The binocular frame holds two switchable rectangular lenses and is worn on the head. You can flip up either lens to use a single eye, which reduces strain during long sessions and lets you alternate eyes.

How do I install the interchangeable lenses and which step do users often miss?

Lenses snap into the frame slots; the set includes 5 pairs (2X, 4X, 6X, 10X, 13X) that combine up to 23X. Users often forget to match each lens to its marked focal distance — 13X needs 1.52 inches — or they try using both eyes at high power, which causes blur.
