Circadian-lighting spectacles achieve global sales

The manufacturers of a pair of special LED spectacles which it claims can adjust the wearer’s circadian rhythm say sales are thriving, with customers in 40 countries.

The Australian company says its Re-Timer spectacles – developed at Flinders University in Adelaide by sleep specialists Professor Leon Lack and Dr Helen Wright – are scientifically proven to re-time the user’s body clock. 

The company has 11 patents patents and has conducted five clinical trials into the performance of the Re-Timer technology. The product works by suppressing the body’s production of melatonin, the sleep hormone our bodies produce which makes us feel tired.

The spectacles deliver green-blue light to the eyes via two LED lights mounted on the frames. The firm says this is the most effective colour of light for treating seasonal affective disorder, or the so-called ‘winter blues’.

The company says that because the lens of our eyes becomes cloudy and yellows as we age, it restricts blue light, so green light – the Re-Timer peaks at 500nm – is a superior treatment option for older people.

Re-Timer, which costs  £149 (US$215), should be worn for 30 minutes a day.

The research at Flinders University found that the circadian clock can be advanced to an earlier time or delayed to a later time when using light comprising a peak wavelength in the green-blue spectrum.

The firm says that light is effective not only for those who suffer with clinically diagnosed insomnia, but also in a population of healthy sleepers looking to optimise their sleep–wake rhythm and extend their total sleep duration.

 

 

Human-centric spectacles? Gordon Routledge isn’t a fan…

It’s worrying times in the world. Here in the UK we face our Brexit referendum on quitting the EU, the US has an interesting presidential dilemma and the trouble in the Middle East hangs constantly over our heads. 

When storm clouds are gathering, people put off making decisions and tighten the financial belt until the dangers passes. 

So in these troubled times, we often need find quick and effective ways of saving money. Inspiration can be found in the most unlikeliest of places, and I suggest you turn to the money saving tips which have for decades being served up by the British adult comic Viz. Examples of its Top Tips include:

  • ‘Don't waste money buying expensive binoculars. Simply stand closer to the object you wish to view.’
  • ‘Save a fortune on your laundry bills. Give your dirty shirts to Oxfam. They will wash and iron them and you can then buy them back for fifty pence.’
  • And perhaps my all-time favourite: ‘Don't waste hundreds of pounds on expensive carpet. Simply buy two small pieces - attach them to the bottom of your feet and get that quality carpet feel throughout your home.’

It's this last one which has been seized upon by the lighting industry. We all wish that users of lighting would recognise the importance of better colour rendering or invest in the latest human centric technology to improve people's abilities at work, speed up recovery times in hospitals, counteract jet lag or aid a better night’s sleep. 

This is still an emerging field of application and it's tempting just to ignore the science, complex design work and just go for the cheapest LED panels.

Well relax, here’s my top lighting tip: Go ahead and buy the cheapest, nastiest LED panel you can find, the one with the lowest possible colour rendering and the alien autopsy white. Choose enought enough lumens to do the job and generally find your way around the space without tripping up. 

Then buy a pair of these so-called light therapy glasses to correct all of the world’s lighting ills. You too can look stupid for just £149.
