FAQ

DOES NETROPTER REQUIRE TRAINING?

NETROPTER’s intuitive interface and great ease-of-use requires minimal
training. The use is very similar to a conventional phoropter or lens kit. The

more you use it, the more condent you will be with the process.

WHAT DIFFERENTIATES NETROPTER FROM OTHER EXISTING
VISUAL ACUITY MEASUREMENT SYSTEMS?

NETROPTER is the world’s rst portable phoropter. It provides the ease of use,

precision, and compact form factor of a phoropter with all of the portability of
a trial lens kit. Unlike a trial lens kit, you can’t lose individual lenses, mistakenly
grab the wrong lens, or drop the kit and have to reorder 200 individual lenses.

DOES THE NETROPTER HAVE AUXILIARY LENSES (EG. PRISM
LENSES, POLARIZED FILTERS OR RED-GREEN FILTERS, ETC.)?

Currently, NETROPTER only contains sphere and cylinder lenses.

IS THERE A VERSION OF THE NETROPTER FOR POSITIVE CYLINDER?

Currently, there is only one version of NETROPTER, which has negative
cylinder lenses and labels.

IS IT NECESSARY TO LOCK THE PD IN ORDER TO RUN A VISUAL
ACUITY TEST?

We recommend that the PD lock is engaged during testing to ensure that the
patient doesn’t accidentally change the PD while handling the NETROPTER.

CAN YOU REST YOUR ELBOWS ON A TABLE WHILE USING
NETROPTER?

Yes, for users who are elderly, disabled, or for any reason unable to hold the
Netropter in a stable manner, it is recommend to have the user rest their
elbows on a stable surface while holding the Netropter for added comfort
and stability.

CAN A SUBJECTIVE REFRACTION BE PERFORMED USING THE
NETROPTER?

Yes! Any qualied person can perform a standard subjective refraction using

the Netropter by adjusting the knobs while the user is looking through the
Netropter.

DOES NETROPTER DO A FULL EYE HEALTH EXAM?

Caution 1 - No, NETROPTER is not an intended substitute for a full eye
health exam. EyeNetra encourages you to consult with your optometrist or
ophthalmologist.

Caution 2 - NETROPTER does not measure any higher-order aberrations or
quantify retinal conditions.
