Overnight lenses gradually changed the shape of Claire's corneas
Eye Health Claire Robson discovered the use of amazing, new lens technology to help correct her short-sightedness.
Having experienced moderate short sightedness in both eyes, and astigmatism in her right eye, Claire Robson had to wear glasses all the time.
"In my first year of university and I was struggling to wear lenses comfortably for more than four hours."
She first realised she had mild visual impairment when she was 10, struggling to read writing on the whiteboard at school. “When I first got glasses, I only used them occasionally but by the time I was 12, my eyesight had deteriorated so much that I began wearing glasses full time and have done since. My main symptom was struggling to read things from boards and signs,” Claire recalled. She began wearing normal contact lenses at the age of 13, before being told about nocturnal lenses. “It was only when I was in my first year of university and I was struggling to wear lenses comfortably for more than four hours at a time that I remembered these nocturnal lenses.”
Discovering Ortho-K lenses
Ortho-K lenses are a type of hard lens worn at night changing the shape of your cornea so when removed, vision should be corrected or at least significantly improved.
If worn for around six hours a night (depending on the individual), the user should have corrected vision for the following day, without the need for contact lenses or glasses. Claire added: “With prolonged use, some users find they only need to wear the lens every other night for the corrected vision to remain. It is a reversible treatment so may be favourable to those concerned about permanent damage.
"I was looking for an alternative to normal contact lenses/glasses but laser eye surgery didn’t seem viable."
Claire continued: “Ortho-K appealed to me as I had worn normal contact lenses full time for about six years and gradually found my eyes were very dry and irritated. I was looking for an alternative to normal contact lenses and glasses but laser eye surgery didn’t seem viable as I suffered from dry eyes and my prescription wasn’t yet stable for a long enough period. Ortho-K seemed to provide an alternative to this whilst providing me with the freedom of not having to wear lenses or glasses during the day."
How do hard lenses feel?
"It's much easier to go to the gym/exercise, particularly in air-conditioned rooms."
Claire explained that the feeling of wearing them was unusual at first but added: “Since you are asleep, any discomfort that I would normally have as a result of my dry eye is not noticeable.” It’s made a huge difference, with Claire commenting: “Not wearing lenses or glasses during the day has made it much easier to go to the gym/exercise, particularly with air-conditioned rooms, I don’t have to decide between wearing lenses for lectures or wearing them to go out in the evening.”
