We have developed an easy-to-use sleep calculator. Simply select the following from the drop down menu:

Whether you wish to change the time you sleep or the time you wake
The desired time you wish to sleep or wake
The time you currently wake
The time you currently fall asleep

A customized schedule will be generated for you, based on the information you have entered. The schedule will outline the best time to wear Re-Timer glasses to influence your sleep cycle.

Questions? Contact our helpful staff to confirm this schedule is right for your sleep pattern and for how you want to change your sleep.
