i can see your microphone, and i can see that you are smiling and i can see the buttons on your shirt. take a look at the audience. yeah. they are waving! i can see there is a lady in the front with a red jacket and the guy next to her is wearing stripes. oh, my god, it is so amazing! applause. i didn't quite realise how many people were there and then i put them on and i could see everybody in the audience. it was a scary feeling, actually. something maisy felt especially robbed of through this traumatic experience was her ability to read herfavourite books. we have a copy of harry potter and the philosopher's stone here. do you think you would be able to read us the first few sentences if i hold the microphone up? 0k. can you see it? yes. she cries. i'm sorry.
12:46 pm
0k. "mr and mrs dursley of number 4 privet drive were proud to say that they were perfectly normal, thank you very much." applause. it made me really happy that i could have that back, that thing that was taken away from me, to have it back was lovely. i really do miss the sensation of purchasing a book, bringing it home and reading a book and to think in the future that this kind of technology may be quite mainstream and that ability will be back for me, it is a wonderfulfeeling. it has been a very overwhelming experience, but a really great one as well, i am really grateful. this really was an emotional moment for all of us. but what about other types of vision impairment? jen copestake has been looking at a piece of technology aimed at people who are colourblind. but does it work?

it looks so different! i'm notjoking. it looks so different. that's the real world. that's how we see colour. this was the moment nine—year—old sebastian tried his enchroma glasses for the first time. designed to help improve the sight of people with certain colour deficiencies, his video was similar to many others posted online. there are so many different greens! oh, my god, sweetie. some of these videos have millions of views on youtube. your bag! and a quick internet search sets up dozens of fundraising pages set up by families trying to raise money to purchase a pair. this could be because the glasses are not cheap. they start at us$349 for adults and $269 for children, with similar prices in the uk. sebastian's father chris first heard about the glasses through watching
12:48 pm
a video and was keen for his son to try them out. i think you probably feel, as with all disabilities for children, powerless and very keen to try and do anything you can to improve or correct even partially, that disability. sebastian was born with a genetic colour deficiency called protanomalous dichromacy. this gives people a decreased sensitivity to red light in particular. people with this deficiency are often called red—green colourblind. about 8% of men and 0.5% of women worldwide have a degree of colour deficiency in their sight. i met sebastien and his father at the institute of ophthalmology at university college in london. i have this book here. what colour do you see this as? i think it is red but i know it is pink. i find that fascinating. put your glasses on and tell me what it looks like. now i see it as definitely pink.
12:49 pm
if you take the glasses off again, we've got quite a few balloons here. what colour is this balloon? i see it as green but i know it is orange. wow. and with the glasses on? now ijust see it as orange. the glasses are said to work using spectral notch filters that actually remove part of the colour spectrum. professor andrew stockman is going to run through some traditional colour deficiency tests with sebastian. these are called ishihara tests, and they're tests for colour deficiency. this example you can definitely see, most people can see, all the colours. what number do you see? a 12. the ishihara test works by showing a number that is slightly different colour to the dots in the background. the glasses don't seem to be helping sebastian with this test. do you see any numbers here? no.
12:50 pm
and how about here? a10? and does that change when you wear the glasses? i slightly think it's a 20? that is closer. it slightly improves your discrimination but you would still not pass a colour test. i'm sorry. there are better results with this test which looks at different colours of wool. this one changes so much. it changes from a green to a very standard pink. and this one where sebastian said he saw a shape he could not see without the glasses. i see a pink circle and a pink triangle on a grey background. what do you see? i sawjust a blue circle but when i put the glasses on i saw a triangle here. so before did you not see a triangle?
12:51 pm
no. what is going on? we are removing part of the colour spectrum. it changes the apparent colour of light. and it's more than a placebo effect? oh, yes. it definitely changes the appearance of coloured lights. i spoke to the company's president via skype from california who said that the glasses are only sold as an optical assistive device. it is important to understand that the glasses are not a cure for colourblindness. they should help the person to see colour in many situations but they don't necessarily provide normal colour vision. recent peer—reviewed research from the university of grenada conducted on 48 people with colour vision deficiency concluded that the enchroma glasses introduce a variation of perceived colour but do not improve results in diagnostic tests for colour deficiency or give the wearers normal colour vision. enchroma provided us a statement regarding the study saying only its indoor use glasses were used on two tests with the subjects wearing glasses for a few minutes at a time.
12:52 pm
they said this would tend to minimise any results. for chris, the science behind the glasses is less important than the experience his son gets while wearing them. yes, of course, if i thought that him wearing the glasses was harmful then i would be far more concerned. if it is a parlour trick, to be brutally honest, i don't really care. but others may expect more definitive results, especially considering the marketing hype and luxury pricetag. these beautiful tulips were generated by a computer programme. the realism is uncanny, and that is because the algorithm these beautiful tulips were generated by a computer programme. the realism is uncanny, and that is because the algorithm that generated them was trained on 10,000 pictures of real tulips. anna ridler, the artist behind this work, then hand—annotated each picture. for each photograph i wrote what colour it was, how stripy it was, what type of tulip it was,
12:53 pm
what state it was in, so if it was a bud or if it was dead, and i used that information to then use machine learning to train an algorithm to produce these moving image pieces. i had read about tulip mania which was this in dutch history in the 1630s when the price of a tulip went at one point for the same price as an amsterdam townhouse, and it was the first known speculative bubble. and i was interested in kind of comparing this moment in history with speculation that is going on now around cryptocurrencies. so in this piece the tulips are kind ofjittering and flickering, that is because the way the tulips have been created by the algorithm is controlled by the price of bitcoin. so as the tulips change, that is because the price of bitcoin is changing. as beautiful as these tulips are, every so often the realism falls away, and you start to see the artifice.
12:54 pm
part of the reason that i display my dataset as a separate work is to really kind of emphasise the humanity and humanness that sits behind all of these processes. and that is it for the shortcut of click from hay, the full—length version has so much more from this amazing festival. you will find it on iplayer right now, and if you need us during the week we are on social media, youtube, instagram, facebook and twitter at @bbcclick. thank you for watching and we will see you soon. hello. a quick glance and you could be

forgiven for thinking it is the med — glorious blue skies and azure seas, but it is our own beautiful st ives in cornwall this morning. some sunshine and mediterranean warmth across the southern half of the uk. through the first part of the weekend, at least, that one feeding up from iberia. to the north, you can see the paler colours on the chart behind me. rather more average temperatures. and by sunday, we see cooler weather pushing into the west as a low pressure begins to take an increasing influence. however, this afternoon, plenty of sunshine for south wales, the midlands, perhaps increasingly even into the north east of england and the temperatures shoot up in that sunshine, perhaps up to 27 across eastern england in the afternoon. that will make it the hottest day of the year so far. further north, much more clad, drizzly rain, showers for the north west of scotland and temperatures capped in the high teens. not a bad evening. the cloud thins and breaks
12:56 pm
before our next area of low pressure feeding from the atlantic, bringing quite heavy rain into scotland by the end of the night. a pretty muggy night, lows in some spots of 16 degrees. sunday, as this front pushes into the west, it will introduce some fresher air. but ahead of that, in the east, another warm day, with sunshine, temperatures across eastern england could easily get up into the mid 20s. further west, showers from the get—go. more persistent rain clears from scotland, but perhaps the odd heavier shower for scotland and northern ireland with thunder later in the day. and a breezy day, quite gusty where we get heavier showers. cloud fills in across eastern england later in the day, but still, temperatures possibly into the mid 20s. more widely, around the high teens or the low 20s across the uk for sunday. by monday, the front is on the continent, we are all into fresher air and for the start of the new week, we are opening our doors again to the atlantic,
12:57 pm
feeding areas of low pressure. so an unsettled scene for the weekend, quite changeable weather, sunshine one day and showers the next, and temperatures return to much more average values.
