Mellsop said part of his work involved helping children whose eye muscle movement developed more slowly than others' to get special glasses or do eye exercises to be able to learn to read.
“That’s been the most satisfying thing that I’ve done,” he said.
“If they don’t get that help, they’ll be stuck all through school.”
Any child with reading difficulties should be given an eye test and this was something schools had become more proactive about over the years, he said.
Mellsop spent time seeing schoolchildren who were sent in a minivan from Castlecliff School to ensure they did not have undiagnosed vision issues and were wearing properly fitted glasses with accurate prescriptions.
The cost of an optometrist appointment was often a barrier for families, and the support offered by Work and Income New Zealand for glasses subsidies was vital, he said.
Over his career, Mellsop had noticed a growing awareness among optometrists about the impact visual-related learning difficulties could have on a person’s life.
“If you were to screen people in the prison population, a lot of these people have got visual problems that have never been picked up or treated,” he said.
“They’ve struggled and not been able to keep up; so they act out.”
Advancements in stronger instruments for optometrists had allowed the industry to spot patients’ eye diseases at much earlier ages, he said.
But the rise of mobile phones and computer-based work meant increased screen time was impacting people’s eyes.
“When you’re sitting looking at a screen, your eyes are at a set distance, and so they’re not moving around much and it’s quite stressful on our visual system,” Mellsop said.
“If you’ve got any small visual error, it’s more obvious and so people who would get by if, say, they were working on a farm, now can’t if their job is on a screen.”
This meant people who previously would not have used glasses now needed them, he said.
New Zealand’s ageing population had also created more demand for optometry with a higher prevalence of eye diseases needing treatment.
In his retirement, Mellsop plans to spend more time tramping and volunteering at community events through the Central Baptist Church and Whanganui parkrun, while maintaining a connection to the eye industry through mentoring up-and-coming optometrists.
“I think now’s the time to give it up, and I’m ready,” he said.
