Have you noticed how many of your friends or colleagues complain about being tired and not being able to get a ‘good night’s sleep’?

Medical research indicates that the number of individuals who are suffering from sleep disorders has increased dramatically in recent years. While some of the blame is as a result of stress and poor lifestyle, the main culprit is thought to be the amount of blue light in our modern environment.

Digital devices including LED televisions, cellphones and tablets all produce high levels of blue light as does lighting from modern LED lights and compact fluorescent lamps – fluorescent lights produce about 25% more blue light and LEDs, about 35% more than older, traditional incandescent lights.

This blue light suppresses the production of melatonin – commonly called the ‘sleep hormone’, which is necessary for sleep to take place and plays an important role in controlling one’s circadian rhythm.


The circadian rhythm is the 24 hour cycle of day and night which controls our sleep patterns and is adapted to the earth’s natural rhythm of day and night.

Sunlight also contains blue light, therefore as the sun rises melatonin production is suppressed and our bodies wake up, at night as the sun sets and light fades into darkness there is less or no blue light and melatonin is produced preparing the body to move into sleep mode.

Nowadays, however, artificial light from lamps and particularly from electronic devices, means that the brain struggles to distinguish the change from day to night, melatonin production is suppressed and so our bodies’ are unable to move effectively into sleep mode.

In order to adequately prepare the body for sleep and allow sufficient melatonin production, one should not be exposed to blue light for at least two hours before bed time.

SleepSpec – a pair of spectacles with specially manufactured scientifically developed orange lenses provide a solution to this modern dilemma. These lenses absorb all blue light, allowing for melatonin production

SleepSpec3The advantage of the SleepSpec shades is that you are able to carry on with all normal activities whether it be working, watching television or reading e-books without the negative side effect of not being able to go to sleep when switching off the light.

It is also important that one’s room is made as dark as possible and that the spectacles are only removed once the light, tablet, television etc have been turned off. One can purchase a torch with an orange light which should be used at night to see, rather than turning on conventional lamps or lights, which will immediately disturb sleep.

The health risks of poor sleep and suppressed melatonin include an increased risk of cancer, impaired immune system function, obesity, diabetes and heart disease. There is also new research which links sleep deprivation to mental illnesses such as depression, dementia and Alzheimers.

SleepSpecs can be purchased online from You can also find out more and shop directly for SleepSpecs by visiting the SleepSpecs Facebook page or call 011 884 5624.
