Few physicians have shared their initial concerns about the durability of the C- band given its lightweight plastic construction. High quality plastic was used in the I-beam shape to provide sufficient structural rigidity while providing feather light headband for improved comfort. None of physicians have yet to return the headlight due to mechanical failure. In fact, most physicians love their Dr. Kim Headlight for its untethered lightweight convenience and comfort.

Lens is selected based on two parameters: Pupillary Distance (PD, in mm) and Dioptre. For example, a lens with 58-1.5 indicates a PD of 58 mm and dioptre of 1.5 (mild farsightedness). Since lens provide generous field of view, don’t worry about fitting PD exactly. A loupe with closest PD should be adequate for your sight. Please contact if you have any question about how to select right lens for your need.

Dioptre range from 1.5 to 3.5 in 0.25 increment. For those with mild farsightedness (hyperopia), 1.5 dioptre is recommended. Dioptre of 2.5 and 3.5 are recommended for those with moderate and severe farsightedness, respectively.

You should take reasonable precautions not to drop the headlight. Also, be gentle especially when pushing down the dual LEDs apparatus to turn on the light.

Please keep Dr. Kim Headlight System clean and dry. This headlight should not be used when wet. If the headlight gets wet, discontinue the headlight immediately. Be sure to turn off the headlight immediately with gloved hand, remove the battery, and completely dry the C-band to minimize the risk of electrical shock.
