YouTuber Mr Beast, 24, pays to cure the sight of 1,000 blind people trends now

YouTube's most subscribed individual just cured 1,000 people's blindness by paying for their simple eye-surgery.

Jimmy Donaldson, a 24-year-old known online by his moniker MrBeast, just released a video detailing the scores of people from the US and across world whose severe cataracts he had removed with the help of a the non-profit eye care organization, See.

MrBeast also gave away $10,000 to a number of patients, bought one a Tesla, and even donated $50,000 to another's college fund. He also donated $100,000 to See.

Donaldson is known for his outlandish stunt videos - which include him being buried alive for 50 hours, and another wherein the last person to take their hand off a private jet gets to keep the plane. In addition to being YouTube's most subscribed individual, he is also one of the website's highest earners.

In the video, MrBeast shows patients getting their bandages removed after surgery, and shows their reaction. For many of them it was the first time they had seen properly in decades.

One patient was a man named Charlie, who's deteriorated vision prevented him from working anymore. After receiving the surgery, Charlie is able to see again and MrBeast gives him $10,000.

'I just haven't been me for the last 62 years,' one patient tells MrBeast in the video, 'I can actually see your face.'

Another man said the first thing he wanted to see when his bandages came off was his son, who he said had been his 'rock' throughout his vision problems. 

'Seeing him, seeing his face, you know, that's what I miss the most,' he said. 

As soon as he came out of surgery, his son was there and the two embraced in tears.

'I can see everybody's facial features now,' he said, wiping away a tear. 'It's a little blurry with my tears coming out.'
