How can I measure my Pupillary Distance (PD)?

You can assess your PD with a help of another person. Pupillary
Distance (PD) is the distance between your pupils. Please ask the person to
stand 12-16 inches (your typical working distance) away from you. Ask the
person to measure the distance between your pupils in millimeter (mm) with a
ruler while you focus your eyes on that person’s nose.

Alternatively, you may obtain your PD from your ophthalmologist/optometrist. Since PD is typically measured for far vision, you
would need to subtract 2 mm to arrive at your PD for your typical working
distance.

How do I select optional lenses to enhance my vision?

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.

How to select an appropriate Loupe for my vision?

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.

What is the Longevity of Dr. Kim Headlight System?

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.

What are differences between loupes and telescope?

Loupes provide a 1.5 – 2.5x magnification and generous field of view while the telescope lens provide 2.0x-3.0x magnification and narrower field of view. 

Loupes are available for specific pupillary Distance (PD) and diopter (farsightedness). On the other hand, the telescope has a built-in focus adjustment for each eye and a
mechanism to accommodate a range of typical PD. We will ship a telescope to
your specified PD but you will need to adjust focus for your eyes.

Whether to choose loupe or the telescope is
totally your personal preference. Most physicians find Dr. Kim Headlight with a
customized loupe satisfactory and a cost-effective way to begin. You can also
acquire the telescope if you require greater magnification.

Can I take digital photos using Dr. Kim Headlight system?

We provide an optional
digital camera (D-CAM2) so you can take photos/video recordings of what you
see. This small light-weight digital camera system can be mounted on C-band and
loupe seamlessly. Operation of the digital camera requires USB connection to
Windows 7 compatible PCs. Photo or video can be captured and saved from a
custom program.

What type of batteries cell do we use?

Our batteries use CR-V 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.

What should I do if light does not turn on? Trouble shooting instructions.

The most common reason that light does not turn on is the lack
of battery power. Please check the battery to make sure it is placed properly,
that the brightness dial is not in off position (turned all the way to downward
position), and that battery is not out of power. Placed a freshly charged
battery, adjust the brightness dial setting to middle, and turn LEDs on. If you
still experience problem, please contact us.

Incidentally, when placing battery in the charger, be sure that
battery contacts are properly aligned with the contacts of the charger.

Precautions and maintenance

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.
