Head magnifier Discovery DHR 20 rechargeable — Discovery DHR 20 Head Magnifier

The Discovery DHR 20 rechargeable head magnifier is a hands-free optical aid designed for detailed close-up work. It combines magnification lenses with an integrated rechargeable LED illumination module to provide consistent, adjustable light and clear magnified viewing. The head-mounted frame distributes weight across the forehead and temples, allowing extended use while keeping both hands free for precision tasks.

Advantages

The integrated rechargeable illumination ensures stable light output without the need for disposable batteries, while the head-worn design offers improved comfort and balance compared with handheld magnifiers. Multiple magnification lenses or lens inserts can be used to adapt viewing power, and the adjustable visor angle positions the optics for optimal focus. The construction supports prolonged use during hobbies, electronics repair, inspection, or reading small text.

Suitable for

• Electronics assembly and repair
• Model making and detailed hobbies
• Jewellery inspection and small-part assembly
• Reading small print and document inspection
• Quality control and visual inspection tasks

Key specifications

• Head-mounted frame with adjustable fit for forehead and temple support
• Built-in rechargeable LED illumination providing consistent, directed light
• Interchangeable magnifying lens options for variable magnification levels
• Adjustable visor angle to set working distance and focus plane
• Lightweight construction for prolonged wear without excessive strain

How to use

Charge the unit according to the manufacturer’s instructions before first use. Fit the head-mounted frame and adjust the strap or tensioning points so the magnifier sits comfortably and securely on the forehead. Install the desired magnifying lens or insert, switch on the LED illumination, and adjust the visor angle to achieve a clear focus at the preferred working distance. Use the illumination control, if present, to set brightness to a comfortable level that reduces glare and eye strain.

Usage recommendations

For best results, work in a stable seated position and position the workpiece within the recommended focal distance of the selected lens. Recharge the unit after extended use and avoid exposing the device to excessive heat or moisture. When changing lenses, handle optical surfaces by the edges and clean with a soft, lint-free cloth to maintain clear visibility.
