Ortho-k lenses continue their rise in the public's minds, with one US publication discussing its use for children.
With a recent study suggesting that the progression of shortsightedness, or myopia, can be stopped or slowed by the lenses, 12-year-old Isabella Jorgenson tried out the overnight correction lenses.
Her mother, Sheri Jorgenson, told abc12.com said: "We're looking to see if we can stop the progression, and I said, 'that's what we want'."
Optometrist Rob David spoke further about ortho-k lenses. "It's flat in the centre and steeper on the sides."
He added that the lenses would not permanently correct the problem but it would "reduce the progression".
Ms Jorgenson found that daily wear lenses were too difficult for her young daughter to deal with and the bonus with ortho-k lenses is that parents can see what their children are doing with them.
As they are worn at night a mum or dad can stand by and assist a child before bed and when they wake up in the morning to take them out.
