A teenager with a devastating eye condition has made an emotional appeal for his estranged father to come home — so he can see him before he goes blind.

The Gazette reports that  Harry Lovett, 16, is slowly losing his vision and suffers from a number of health conditions including cerebral palsy, autism, dyslexia, epilepsy and impaired hearing.

Medics have warned that his condition is already is beginning to deteriorate, and that he is likely to lose his sight for good.

Instead of letting it affect him, defiant Harry compiled a ‘bucket list’ of the things he hopes to see and experience before he goes permanently blind.

But one of the most heartbreaking wishes on his bucket list is a plea to his father Calum, who he hasn’t seen or heard from in two years.

The family have not heard from father-of-two Calum Lovett who left the Bridge of Weir home back in October 25, 2013. 

Speaking on behalf of Harry, sister Bryony, 18, said: “When my dad first disappeared, Harry thought he was dead.

“But we have since heard that he is alive, which we are glad of, but we would rather he was alive and in our lives.

“Our dad has missed so many of Harry’s achievements over the last few years, which is sad because he should be a part of them.

“It was completely out of character for our dad to disappear so suddenly as he was such a family man, it’s turned our lives upside down.”

Inspirational Harry’s achievements over the last two years have been endless; being nominated by the Royal Blind School to take part in this year’s Relay, scooping silver in the British Judo Championships and having won Gold in the Swimming Nationals.

But throughout all his accomplishments, the youngster has been nursing the secret heartache of missing his father.

Harry’s mum, Fiona, 42, made a desperate appeal for the father of her two children to get in touch and let them know he is safe.

She said: “My worry is that Calum thinks the kids don’t want to see him — completely not the case — so I want him to know that.

“Harry has achieved so much on his bucket list but the one thing he hasn’t managed to tick off is seeing his dad again.”

Over the last few months, brave Harry has been trying to see as much of the world as possible so he can have clear memories of his adventures when he loses his sight.

And last month, one of his biggest wishes came true when he was offered the chance to be driven round a race track, in Harry’s words, “really fast.”

Harry, who attends The Royal Blind School in Edinburgh, described the experience — provided by top racer Chris Knox — as “the best moment of my life.”

His sister Bryony was the first to come up with the idea for Harry’s list and, alongside doting mum Fiona, the family jotted them down and vowed they would be soon ticked off.

Now he has just a few goals left in including; going on safari and see hippos, giraffes and elephants, discovering how the sound and lighting desk operates in the theatre and learning to take great photos and buy a great camera and lenses.

But the biggest and most touching goals on his bucket list are his vow to “make my mum prouder than she has ever been” and reunite with dad Calum.

Harry said: “There’s a lot of things I want to achieve, and one if them is to be able to take pictures, so I know how to use a professional camera before I lose my sight.

“I’d love to be a photographer because I’ve always been fascinated with cameras and pictures, if I can see them in my head, it means I’ll always be able to remember them when I can no longer see.”

Although the family have no time scale as to when Harry will lost his sight for good, he is already beginning to struggle with some everyday tasks.

However, it certainly doesn’t stop him from achieving his goals, having had the chance to even meet the Queen on her 80th birthday.

Speaking at the family home, mum Fiona said: “I’m often an emotional wreck — but it’s tears of happiness.

“Harry is just amazing and hilarious, he just gets on with things and never lets anything get him down. He does get frustrated at times.

“Like recently he was trying to watch the football but could see the players and not the ball.

“It’s upsetting but Harry is so resilient. We’re determined to give him the memories he wants to make before he loses his sight.”

Bryony added: “We were all very close to our dad but Harry misses him the most and it still affects him.

“This is our last chance to try and get our dad to get back in touch.”
