What is myopia (short sightedness)?
Clear vision occurs when light is focused on the retina (the back of the eye). For someone with myopia (the technical term for short sightedness) light comes into focus too far forward in the eye, causing distance objects to appear blurred. This is because the eye is too long for the power of the eye.
How short sighted am I?
|Low||up to -3.00 DS|
|Intermediate||-3.00 DS to -5.00 DS|
|High||More than -5.00 DS|
Why is myopia a problem?
As well as needing thicker glasses or contact lenses to correct higher levels of myopia, myopia brings an increased risk of eye disease and poor vision. Having myopia increases the risk of eye disease, in particular retinal detachment, myopic macula degeneration and glaucoma. The higher the myopia, the greater the risk.
Over many years, research has been carried out to find an effective way to influence the tendency for myopia to get worse as children grow and develop . Recently there have been some exciting new developments in the area of myopia management and we now have several options to consider, both in spectacle lenses and contact lenses.
Did you know?
If one or both parents are short sighted, this increases the risk of a child becoming myopic.
Each generation tends to be more short sighted than the previous.
The younger a child first becomes myopic the higher their myopia is likely to become.
UK prevalence of myopia has doubled in the last 50 years.
50-53% of UK university students are now myopic.
Things are even worse in Asia; 93% of Taiwanese medical students are myopic.
Myopia is now the most common cause of impaired vision (poor vision even with glasses) in the developed world.
What is myopia management?
In the past, we have had no option but to simply correct myopia with conventional spectacles or contact lenses to focus light at the back of the eye. Now, following extensive research and lens development, we have options to both correct myopia and reduce the progression of short sightedness.
At Keyes Eyecare, we have two options for myopia control. These can either be used separately or in conjunction with one another. These options are contact lenses developed for myopia management and a new spectacle lens, MiyoSmart.
Using this approach, myopic progression can be reduced on average by 50%. This is highly significant, both in terms of the level of myopia that a child develops as they grow and reducing the risk of complication associated with myopia. It is important to note however, that this is an average so some children will have a better reduction in the rate of progression, some will have results that aren’t as good.
How does myopia management work?
Conventional spectacle lenses or contact lenses correct Myopia by diverging central light so it comes into focus at the back of the eye.
However, not all light coming into the eye behaves in the same way; light focussing in the eye peripherally behaves differently to the light coming in centrally.
In children who are becoming myopic, the peripheral light tends to focus behind the retina. Because this peripheral light does not focus on the retina it is thought that the eye responds by growing. Whilst the larger eye reduces peripheral blurring, it also makes the eye increasingly myopic. By wearing glasses or contact lenses prescribed for myopia control, peripheral blur can be managed, and the growth of the eye reduced. Doing this reduces the severity of myopia. On average a 50% reduction in myopia progression is achieved.
