To help determine if you have sensitivity to light treatment, we recommend that you
perform this pretest upon first use of this device:
Step 1 - Start this test with the comfort lens. Turn on the lamp and position it about
18inchesfromyourface.(Donotlookdirectlyintothelamp.)
Step 2 - Operate the lamp for approximately 10 minutes and turn it off. If the light
has caused any discomfort, stop using the lamp and consult a doctor.
If you have no discomfort, you may consider gradually decreasing the
distance from the lamp and increasing the use time, which results in
more lamp intensity and greater effect. You also may change from the
comfort lens to the high-energy lens and repeat the device pretest. For
your initial sessions, you should monitor the degree of any discomfort and
accordingly adjust the time used, lens used and lamp location.
