The following instructions should be followed by people with:

• Delayed sleep phase disorder

Start wearing the glasses 2 hours before you usually fall asleep. Then, you start 1 hour earlier every week until you have reached your preferred bedtime.

Example: John 20 years old, cannot sleep until 4am and therefore misses the first hours of school every day. He wants to be able to sleep from 11pm.

1^st week: Chrono Chrome glasses (CC glasses) from 2am

2^nd week: CC glasses from 1am

3^rd week: CC glasses from midnight

4^th week: CC glasses from 11pm

5^th week: CC glasses from 10pm

6^th week: CC glasses from 9pm

GOAL!

This process takes same time, but reduces the risk for unwanted large shifts in the circadian rhythm that might produce jet-lag symptoms. The gradually advancing start of the darkness-time allows your body to adjust smoothly. For an even stronger effect Chrono Chrome recommends the use of a dawn simulating lamp followed by bright light after waking up.

Side effects, adverse events or injuries related to the use of Chrono Chrome's glasses should be reported to your doctor and info@chronochrome.com without delay.
