First topic message reminder :

The glasses reduce the amount of ultra-violet light reaching key areas of the eye, tricking the brain into believing less harmful rays have penetrated the body.

The result, doctors believe, is that the body produces less of a natural substance it needs to defend itself against harmful ultraviolet light.

The theory will be published tomorrow in a book called Survival Of The Sickest, which analyses the origins of modern disease.

It was written by disease specialist Dr Sharon Moalem, who has studied the process of tanning and ultra-violet, or UV, light.

Sunglasses make the brain think it's dark and this means you're not starting the natural process of tanning.

He thinks it may help explain the soaring rates of deadly skin cancer, or melonomas, in affluent countries.

His research has alarmed skin experts and led to calls for the development of "clear" sunglasses that protect the eye from UV damage but do not trick the body.

Previously, scientists and dermatologists had urged people to wear sunglasses to shield the retina from damage.

It's a startling theory, but seeing as the brain creates other chemicals in response to light, it might very well be true.

Oh, do fuck off, Tommy...

You truly don't have a clue what you are talking about here..

Obviously you know less than zero about sun exposure and skin cancers,  so why do you keep on trying to disrupt this thread ?

He's making more sense than you.

The fundamental question here is - what triggers the production of melanin? Is it UV rays going into the eyes or UV rays hitting the skin?

If it's UV rays going into the eyes, then why doesn't someone produce melanin when they're covered up with clothing?

Could be ballcaps, except wide brim hat's have been around for ever.  

I wonder if obesity could increase the chance of skin cancer?

So is it a choice between skin cancer and cataracts then? Or cover up and wear la very large brimmed hat. or would the hat have the same effect as the sunglasses?

Then there is this. One thing that has changed is the use of sunscreen. In the past, people just wore long sleeves and hats. now they lather on chemicals.

I rarely use the stuff, unless I'm going topless. Shocked Cool
