Almost forty pairs of glasses were handed out to Indigenous children during a visit to Mount Isa and Cloncurry by a team of volunteers from OPSM's OneSight program.
Karen Hall, regional sales manager for OPSM, based in Penrith, was one of 20 people to volunteer to provide free eye-care and eye-health education to Indigenous Australians.
The clinics, held at schools in Mount Isa and Cloncurry, were part of the OPSM OneSight Indigenous eye health program.
Ms Hall said the team saw 527 students, conducted 80 eye tests over two days and handed out 39 pairs of glasses.
"The kids were wonderful, they were very enthusiastic," Ms Hall said.
"I wanted to be part of something local and give back to the community, especially our future generations.
"Sight is so important to early learning and personal confidence for young Australians, so it's an honour to volunteer for such a great cause," she said.
"It is humbling to think that we have helped so many people to see better in just two days," she said.
