Our warranty covers our product(s) from any defects/malfunction for one year from the date of purchase. The warranty, however, does not cover accidental damage (for example, broken loupe due to a drop). After one year, we will repair/replace parts at additional cost. Please contact us if you have any issues or questions.

In addition to providing optimal lighting, Dr. Kim Headlight System can further enhance your vision with the use of lenses. Two types of lens magnifications are available - loupe and telescope. Loupes and telescope are engineered to work seamlessly with the headlight. You can easily attach/remove loupe and telescope as needed. You do not need any special tool. Please note that you cannot use loupe and telescope simultaneously. Only one can be used at a time. However, you may use loupe simultaneously with your eyeglasses. Since loupe/telescope is attached to the C-band and is light in weight, it does not place any additional strain on your nose or neck.

Loupe is selected based on two parameters: Pupillary Distance (PD, in mm) and Diopter. For example, a loupe with 58-1.5 indicates a PD of 58 mm and diopter of 1.5 (mild farsightedness). Since loupes 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 loupe for your need.

See, How can I measure my Pupillary Distance for detail. Diopter range from 1.5 to 3.5 in 0.25 increment. For those with mild farsightedness (hyperopia), 1.5 diopter is recommended. Diopter of 2.5 and 3.5 are recommended for those with moderate and severe farsightedness, respectively.

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 featherlight 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.

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.

Our batteries use CR-V3 Li-ion. Although you can buy any type of CR-V3, we recommend you use Dr. Kim's battery for optimal results. You may order additional batteries [here]
