He was once painted as the "bad boy" contestant of Australia's much-loved Bachelor franchise.

But Jake Ellis says he's moved on from the days of nightclub openings and attending reality star studded events, now focusing on more worthwhile causes close to his heart.

"My time doing that stuff is kind of done I think," he told news.com.au of the latest Bachelor in Paradise series airing.

"I've been very fortunate I feel, doing what I've been doing the past two or three years, using it to help organisations and other people."

The newly-single star, who recently broke up with fellow contestant Megan Marx for a second time, went on last year's Bachelor in Paradise for a second shot at finding love after coming third in Georgia Love's season of the Bachelorette.

"I've done my dash with events," he said.

"You get over it."

But the 33-year-old certainly has time for events of a different kind - charity events and worthwhile causes.

The Gold Coaster, who is already an ambassador for the National Breast Cancer Foundation, has now also taken on helping Guide Dogs.

While he's previously revealed his heartbreak losing his mum Robyn to a 25-year battle with breast cancer in January 2018, he hasn't spoken much about his dad Brian until now.

After 43 years together, Jake's dad's health further declined after his wife died.

Having already undergone a double lung transplant he was still recovering from, Robyn's death rocked the whole family.

Mr Ellis' eyesight slowly deteriorated to the point of having his driver's licence confiscated. He's now in a care facility, which Jake said was tough because his dad had lost his independence at 72 years old.

"In his recovery he aged a lot more," he said.

"It's hard seeing a family member or someone you love lose their independence they've had their whole life.

"It's hard feeling helpless. Anyone who's been together that long, the sense of loss for my dad is a lot different to mine.

"It amplified his health issues a bit, you feel it a lot more and people stress themselves out when they get sick."

Mrs Ellis was also diagnosed with glaucoma during her illness and Jake said she was in constant fear she would lose her sight.

Glaucoma is a common form of eye disease that often runs in families and effects the optic nerve connecting the eye to the brain.

According to the latest statistics from the Centre for Eye Health report, by 2020 more than half a million Australians will be living with sight loss.

Research from Guide Dogs in NSW and the ACT found one third of study respondents felt disconnected from society and like their world was shrinking as a result of sight loss.

Two thirds said they felt depressed.

An overwhelming majority have even experienced bullying and discrimination as a result of their vision impairment.

Together with younger brother Luke, Jake has been supporting his dad through his own vision loss.

"My family is my everything and always has been," he said.

"It's just hard to see. You grow up and your parents are your heroes, they're still my heroes.

"Life's unfair sometimes, it's what you do to change that makes difference."
