Travelling west
Since most people's body clocks adjust more easily to later time zones,
you only have to use the appliance for one day before you travel across
four time zones. Add an additional preparation day for each three
additional time zones. You do not have to use the appliance for more
than three days, even on longer westbound trips. Use the appliance for
30–40 minutes late in the evening. Start two or three days before you
leave. Use the appliance two hours later the following nights.
When you arrive at your destination, try to stay awake until bedtime and
avoid bright evening light (wear sunglasses) for the first few days. Before
you travel home, avoid any bright afternoon and evening light. Use the
appliance in the morning for a few days.

Light intensity

Use the appliance in addition to the normal room lighting. This Philips
appliance is more comfortable to use in a well-lit room. Adjust the
brightness to a comfortable level. Allow a few minutes for your eyes to
get used to the bright light. If the highest setting is too bright for you,
start using the appliance at a lower setting. Increase the light intensity if
you feel no effect after a week.

How to use the appliance

1 Place the appliance at arm's length (at approximately 50-75cm from
your eyes) within your field of vision. The light must bathe your face
(Fig. 5).
- You can read, eat, work at the computer, watch TV or exercise while
you use the appliance.
- For the best results, place the appliance at the same level as your
midriff (stomach area), e.g. place it on the table at which you are sitting.
- Use the appliance in a well-lit room to minimise eyestrain.
