Myopia Control and Ortho-K for Kids
There is, as yet, no cure for myopia. The physical change of the elongated eyeball cannot be reversed (even laser-eye surgery can’t do this) and that’s why myopia control is so important.
The aim is to slow down, or halt, the progression of myopia, and this is becoming increasingly effective, especially in children and teenagers.
Orthokeratology is playing a key role in myopia control all over the world. Recent studies have indicated that myopia develops at a much slower rate, and can even be halted, in children fitted with orthokeratology lenses.
The results vary for each individual child, but most experts maintain that these lenses are the best available option for children suffering from myopia.
Research indicates that children who are genetically predisposed to myopia (children with short-sighted parents) can reduce their chances of developing the condition by increasing the amount of time they spend outdoors.
It is believed that natural, outdoor light on the retina protects the eye from lengthening and therefore becoming myopic.
Around 14 hours a week spent outdoors has been shown to reduce the chance of a person becoming myopic – even in overcast weather.
Unfortunately, once a child becomes short-sighted, the amount of time spent outdoors ceases to impact on the eye, so exposure to natural light is only preventative. It should however, be considered from as early in a child’s life as possible.
Contrary to previous theories, excessive homework or reading are not factors that contribute to the onset of myopia.
Overnight vision correction lenses can be used by both adults and children.
The treatment can be used for eye prescriptions up to -5.00 Diopters (combined prescription).
It is usually used for the treatment of mild to moderate myopia (short-sighted) conditions. This treatment can also reduce other eye problems, like hyperopia (long-sight) and reduce the symptoms in astigmatism (a problem with how the eye focuses light). It is helpful for children, to attempt to slow the progression of myopia.
Young adults that are too young for laser treatment, will find OVC will benefit them as they won’t need to wear glasses or contact lenses during the day for sports, swimming or recreation. If dry eyes prevent you wearing normal contact lenses, OVC would be a good choice of treatment.
People who work in dusty environments, which pose a problem for wearing normal contact lenses, will also find the OVC treatment beneficial.
