Scientists have invented glasses that correct colour blindness.
These sound like high-tech specs. What's the story?
Dr Mark Changizi and Dr Timothy Barber, friends and founders of 2AI Labs in Boise, Idaho, designed the glasses to enhance the wearer's ability to see oxygenated blood.
They thought this would help doctors spot veins and bruises more easily. But it turns out the filters in the glasses concentrate their effects around the wavelengths where red-green colour-blind people have difficulties. It's mostly men who suffer from this condition - one in 10 in fact. Women are rarely afflicted.
Do they work?
Daniel Bor, a colour-blind neuroscientist at the University of Sussex, tried out the glasses by taking the Ishihara test for red-green colour-blindness. He passed with, um, flying colours. However, it seems that the glasses make it more difficult to perceive yellows and blue.
"My daughter's baby monitor has some yellow lights on it and I couldn't see them at all," he told The Times. This means people driving should not wear the specs.
I understand Dr Changizi has a new theory of why primates see colours?
Yes. The old theory is that colour vision evolved to help primates see fruits in the forests. The problem with this is that the diets of primates with the same colour vision vary widely.
Dr Changizi's theory is that colour vision evolved to help primates see changes in blood levels - ie blushing - and help interpret others' emotional state and health.
In this case, the primates with colour vision would be the ones with naked spots on faces and rumps, for example. This turns out to hold true.
Are these glasses available on the market yet?
They are on sale for US$279 (Dh1,024).

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.
