The Discovery Crafts DHD 30 is a head-mounted magnifier with interchangeable and combinable lenses. You can choose the most optimal magnification for the task, your hands remain free, and it has built-in lighting. The magnifier has a short focal length, so it is best suited for repair and survey work, as well as handicraft work. It can also be useful for reading small print.

The lenses are rectangular, designed so that you can see with both eyes at the same time. The lens material is polymer optical glass with a high degree of transparency. Strong, durable material that provides a clear, contrasted image. One or two lenses (one after the other) can be mounted on the magnifier.

The lighting is in the middle and includes two powerful LEDs. The lighting works with normal batteries. The headband of the magnifier can be adjusted to size.
