Some people may believe that
ortho k is a brand new venture.
However, others know that is not the case, with one journalist mentioning all the way back in 2007 that for short-sighted folk, ortho k lenses are a great invention.
Writing in the Independent, Jimmy Lee Sheeve said that from the age of 13 he was forced to wear glasses.
After a few misadventures with contact lenses and a fear of being "zapped by a ray gun" by having laser surgery, Mr Sheeve opted for ortho k lenses.
From just one night of use, he claimed he was "stunned".
"I'd still been slightly sceptical. I thought my eyesight might be corrected a bit with
ortho k - perhaps to the point of being able to watch TV without glasses, but nothing more dramatic. I didn't expect a return to 20/20 vision," he said.
"As far as I'm concerned, it's a minor miracle."
If you don't fancy the risks associated with
laser eye surgery or are looking for an alternative for daily wear lenses,
ortho k could be for you.
