Purple lenses Glasses
Dr Daniel Bor, of the University of Sussex, said: ‘The main thing I have problems with is when people use red and green on graphs in seminars and I can’t tell the difference between them.
‘And there’s my occasionally weird dress sense, which my wife puts me right on. But putting on the glasses for the first time was really quite an exciting moment. I was with my daughter in the gym and suddenly her lips stood out.
‘She was wearing a red-orange jumper and suddenly it stood out from the surroundings.’
The glasses, which were originally developed for medical use, are the brainchild of US scientist Mark Changizi.
The lenses filter out bands of light that interfere with the ability to distinguish various shades of red and green.
Dr Changizi, of Idaho firm 2AI Labs, said: ‘It makes it so they can suddenly see red-green differences in the world which were originally too small for them to notice.’

Wearing the glasses, Dr Bor managed to pass the colour blindness test used in used in schools around the world. However, they were not without their drawbacks.
He said: ‘My daughter’s baby monitor has a yellow light on it and normally I can see that. But with the glasses on, it was completely invisible.
‘Without the glasses, nothing is invisible. It was a bit disturbing that some things disappeared out of my vision.
WHAT IS COLOUR BLINDNESS?
Colour blindness affects around 1 in 12 men and 1 in 200 women in the world.
In Britain this means that there are approximately 2.7million colour blind people (about 4.5 per cent of the entire population), most of whom are male.
There are different causes of colour blindness.
For the vast majority of people with deficient colour vision the condition is genetic and has been inherited from their mother.
However some people become colour blind as a result of other diseases such as diabetes and multiple sclerosis or they acquire the condition over time due to the ageing process or medication side effects.
Most colour blind people are able to see things as clearly as other people but they unable to fully ‘see’ red, green or blue light.
There are different types of colour blindness and there are extremely rare cases where people are unable to see any colour at all.
‘I wouldn’t wear them all the time but if I was going to an art gallery or a flower show, I’d take them with me. I’d really welcome them then.’
The glasses only work for red-green colour blindness. This is the most common form and although rare in women, it affects up to 8 per cent of men.
On his blog, Professor Changizi said: 'Although we didn’t design our technology with colour-deficients specifically in mind, we weren’t too surprised that the Oxy-Iso may help with with red-green colour-deficiency.
'As I have argued in my research and my earlier book, Vision Revolution, our human variety of color vision evolved — above and beyond that found in other mammals — in order to sense these oxygenation variations, allowing us to sense colour-signals on the skin (including blushes, blanches, as well as sensing health).
'So the Oxy-Iso filter concentrates its enhancement exactly where red-green colour-blind folk are deficient.'
Daniel Bor, a researcher from the University of Sussex, said wearing the glasses enabled him to pass the commonly used test for colour blindness, the Ishihara Colour Test, in which patients are shown plates which feature a circle of dots.
Colour blindness sufferers are not able to make out numbers shown made up of dots of a different colour.
'When I first put one of them on, I got a shiver of excitement at how vibrant and red lips, clothes and other objects around me seemed, ' Mr Bor said.
The glasses are already available. However, while they enhance perception of reds and greens, they hamper the ability to distinguish yellows and blues.

What is the difference between anti-glare and anti-reflective coating for glasses? Which one is better for a person using the computer for greater than 8 hours a day? - Quora
Some thing. Anti reflective is correct name. Anti glare is more simple trade version. Neither is reduce glare as such, only reflections created by lens itself. Most of the public unaware that any lens create a lot of reflections and ghost images within. They tiresome and always very irritating. Coatings minimize this problem for wearer.Therefore they help if you have to wear spectacles for vision correction to roughly make it feel not worse than perfect eye without glasses. To get them in order to reduce any outside glare is a folly and dirty sales technic. Scare and sell works pretty w…
