Getting to Know Your Earlens Hearing Aid
The Earlens Hearing Aid uses a small Lens placed in your ear by a physician to
activate your natural hearing system.The behind-the-ear Photon™2 Processor
collects sound and transfers it to the Light Tip, which converts the sound signal
to non-visible light. The Lens collects this light and gently activates your natural
hearing system.
There are important components to your Earlens Hearing Aid that will be described
in this section: the Lens, the Processor, the Light Tip, the Charger and mineral oil.
The components that you will interact with include the Processor,
Light Tip, Charger and mineral oil.

1Sound enters the microphone on the Processor,
which transforms the sound and sends the
audio signal to the Light Tip.
2The Light Tip converts the audio signal into light
and then projects the light wave to the Lens, which
makes direct contact with the eardrum.
3When the Lens is activated by the light wave,
it vibrates the eardrum gently at dierent
frequencies—resulting in rich, natural sound.

The Lens
The Lens is driven by light waves that contain sound information. When the Lens
detects light waves, it gently activates your natural hearing system allowing you to hear
sound. To keep your Lens functioning properly, you must apply Earlens mineral oil
twice a week and avoid placing foreign objects in your ear (such as Q-tips, bobby
pins, and your ngernails).

7
The Photon™2 Processor and Light Tip
The Processor sits comfortably behind your ear. It collects and sends sound signals
to the Light Tip, which then converts the sound signals into non-visible light that is
projected by the emitter. The light from the emitter is collected by the Lens.

10
Mineral Oil
Mineral oil plays an important role in keeping the Lens in position
and properly working. Apply two pumps of mineral oil to each ear
twice a week, or follow the instructions of your physician if you are
asked to use mineral oil more frequently. If you forget to apply the
mineral oil to your ear as advised, your Lens may stop working or fall
out. In the event that you forget to oil as scheduled, apply oil as soon
as possible and then resume as advised.
Detailed mineral oil use instructions are available in the Care and
Maintenance section of this manual.
