Over the last 30 years short-sightedness has increased significantly and now affects 42% of the population2. As short-sightedness is inherited it is now it a key health issue facing families. However the results from a major new study into “Myopia Control”1 have revealed that if children are fitted with special overnight contact lenses the progression of their short-sightedness can be halted.
The SMART Study1 into ‘Myopia Control’ involves over 250 children who are monitored over a five-year period. After two years, the control group wearing soft contact lenses experienced an average increase in their prescription of almost one dioptre (equal to 3-4 lines on an eye chart). The children wearing the new overnight contact lenses experienced no clinically significant increase in their myopia.
Whilst myopia rates in the western world were assumed to be 25%, research published last December 2 reported a rise of 66% over the last 30 years. Short-sightedness is typically diagnosed around the age of 10 and progresses at around -0.5 dioptres per year until it stabilises in the early 20’s. The primary driver of short-sightedness is genetic, if one parent is affected there is a 40% chance of inheriting the condition but if it affects both parents it rises to 75%. However the sudden overall increase has been attributed to modern living. The fact that children now spend around 7 hrs a day staring at computers and mobile phones 4 and less time outdoors in natural light 3 is having a major detrimental effect on the development of their eyesight.
Mrs Huang and her husband are both high myopes and their children have inherited this condition. Valerie the eldest is -3.75D, her brother Antonio is -6.00D and sister Maxine is -1.00D. “I found out about overnight vision correction from my goddaughter in China who has been wearing overnight lenses for seven years. She is now 25 and her prescription has not changed in that time” says Mrs Huang.
Maxine the youngest child stands to benefit most from “Myopia Control”. At six her short-sightedness is still mild and has been caught in time. By fitting her now it is expected that her prescription will remain at around -1.00D and not progress to the higher levels of her brother. Valerie 15, can also benefit from her prescription not increasing and she is noticing other benefits. “As I have got older I have found glasses more inconvenient. I do lots of sport and with swimming I always had to get new goggles every time my prescription changed. Wearing my lenses at night gives me so much more freedom.”
Overnight contact lenses are made using a unique computerised map of the eye surface and are specially designed to sleep in. They gently flatten the cornea altering the angle at which light enters the eye so it focuses correctly on the retina. By holding the eye in the correct shape as the eye develops the lens acts like a dental brace. When the lenses are removed in the morning, full vision correction is maintained for over 24 hours. The lenses can be worn at any age but for children the additional benefit of stabilising their prescription before it becomes too high is significant. In the long term those with high degrees of short-sightedness are more likely to develop retinal detachment, glaucoma and cataracts.
Jennifer Golden CEO of i-GO Optical - which markets the new overnight contact lenses says “Whilst i-GO lenses are relatively new in the UK there are already over 100,000 people worldwide wearing them. They have major benefits for children because of the added freedom and confidence its gives them at school along and more importantly their ability to arrest the development of myopia.”
Shelly Bansal, a specialist contact lens practitioner who has fitted a number of adolescents says ”Over the years there have been many products which have claimed to halt myopia progression in children and now for the first time there is real evidence to support overnight vision correction as a treatment for short-sighted children.”
