Do you have trouble getting off to sleep at night?

Do you continually watch TV, use the computer or read as you can't sleep?

Do your teenage children stay up late on their laptops, DVD players or watch TV, then are impossible to get out of bed the next day?

Zzzz Low Blue Light Glasses

These glasses block the blue light that causes suppression of melatonin.  Blue light is a part of the light spectrum in sunlight but is also found in light from artificial lighting from incandescent and fluroresent bulbs or tubes.  It is also produced by television and computer screens and your bedside reading light. By exposing yourself to this light in the evenings you are confusing the hormones in your body, in particular melatonin which is produced in the absence of light.  The presence of melatonin enables your body to ready itself for sleep and allows you to feel sleepy. 

By using the blue light blocking glasses an hour or two before you wish to go to sleep you will encourage the production of melatonin.  You can continue to watch TV, use the computer or read until you feel sleepy. 

In order to get the benefit of having melatonin present for a longer time it is suggested to put on the glasses a few hours before going to bed.  You may read, watch television or work on your computer according to your routine.  On your way to bed avoid exposing you eyes to white light.  Just a short (5 minute) exposure may undo the good you have done.  If you need to take off your glasses to wash or shower, use an amber nightlight or LowBlueLights light bulb to find your way.  Put on your glasses again if you need to turn on other lights.  Keep them on until you are in your darkened bedroom, and get into bed with the aid of an amber nightlight. 

It may take a week to adjust since you are moving your circadian clock ahead in time.  If you get too sleepy, too soon in the evening, put on the glasses a little later. 

It is important to put your glasses on at about the same time every evening in order to keep you circadian clock at the same setting.  When you go to bed and go to sleep is less important.  Continually resetting your circadian clock reduces melatonin production and can lead to poor physical and mental health.  To maximise melatonin (9-10 hours total flow time) you should avoid ordinary light for 10 hours from the time you put on your glasses. If you need to get up during the night, put your glasses on again. If your daily routine involves being in a dim light setting it is suggested that you get as much natural light as possible.

Note: These glasses may make you fatigued and it is not recommended to wear them while driving or operating machinery.
