How Do Ortho K Lenses Correct Your Vision Overnight?

You might be surprised by the notion of overnight vision correction. How could contact lenses possibly correct your vision while you sleep? Well, for starters, these are no ordinary contact lenses – these are Ortho K lenses. They’re designed to gently reshape the surface of your eye and in doing so, can correct many cases of short-sightedness. Once these lenses get to work at night and you remove them when you wake up in the morning, you won’t need to wear glasses or normal contact lenses during the day. Instead, you’ll experience crystal clear, pristine vision and freedom, of course.


It may sound too good to be true, but the science behind orthokeratology reveals exactly why it really does work.

The science bit

Short-sightedness occurs when the front of the eyeball grows a little too long, which means when light enters your eyes they don’t focus correctly on the retina, but do so just before it, meaning objects in the distance end up looking blurry.

Reshaping the cornea via Orthokeratology helps to accurately focus the light entering your eyes.

The effects last for a day or 2, carry little risk and are completely reversible. Wearing them every night helps maintain clearer vision for longer and it’s a treatment that works for wide variety of ages, with some patients even being fitted with them from as young as eight years old.

Ortho K: the solution for kids and adults

Ortho K is suitable for adults who are short-sighted and want to leave glasses and normal contact lenses behind them, but don’t want to take the risk of undergoing laser eye surgery.

Maybe you love playing sports but are tired of worrying about your glasses getting knocked off your face, damaged, or even causing you injury. Perhaps you’ve tried normal contact lenses but have since developed Dry Eye as a result? Or it could be that you just want to enjoy all that summer has to offer without the hassle of wearing glasses or normal contact lenses all day long.

It isn’t just adults who stand to gain. Ortho K can be used for children who are short-sighted too. It is even proven to slow down the progression of short-sightedness in children, which reduces potential future complications, such as an increased risk of cataracts and glaucoma. As the lenses are only worn at night, parents needn’t worry about their children struggling to put them in or forgetting to take them out; they can be right there helping or supervising them each night and morning.
