At Eyeworks London lots of our younger patients are short sighted (or myopic), we are often asked if there is anything that can be done to prevent the myopia getting worse. The good news is that there are a growing number of options to manage the myopia and lots of ongoing research for more options in the future.
For a number of years Eyeworks London has offered MiSight contact lenses which can reduce myopia progression by an average of 59%. More recently in January 2021 HOYA have developed a new spectacle lens call MiYOSMART which gives similar efficacy but with the convenience of glasses. This is a really exciting development in the struggle against myopia; opening up treatment options to those who were not suitable for contact lenses.
During a routine eye test we will be able to give our younger patients an indication of the risk of developing myopia and discuss treatment options if necessary.
What is myopia?
Myopia causes blur in the distance vision. The blur is caused by the image being focused too soon; in front of the retina rather than on the retina. The usual reason the focused light rays don't quite make it to the retina is that the eye is too long.
In some children as they grow the eyes will grow in length too. The elongation of the eyes will cause the myopia to progress. It follows then that myopia progresses more in late childhood and teenage years and therefore myopia management will be more effective in this age range.
What is myopia management?
Myopia management does not cure or reduce myopia, but aims to slow down the rate at which it gets worse. The eye grows rapidly until early adulthood, so myopia management will usually be continued until at least 17 years old. If myopia management is stopped before the eye has stopped growing, the myopia may start to get worse again.
Why does myopia matter?
There are two reasons why the amount of myopia matters. The first reason is obvious; the higher the myopia the more dependence on glasses or contact lenses. This can be inconvenient and expensive.
The second reason is that large amounts of myopia can affect the health of the eyes. The greater the myopia the longer the eye will be. A physically long eye creates tension on the structures of the eye. Consequently, a myopic eye is more at risk of retinal detachment and maculopathy. Studies have shown that a 1 dioptre increase in myopia will double the risk of maculopathy.
Risk of eye condition with myopia level
||Retinal Detachment||Myopia Maculopathy|
|-1.00 to -3.00
|-3.00 to -5.00
|-5.00 to -7.00
Therefore, every dioptre counts and intervening before the myopia progresses will be beneficial for the health of the eyes as well as reduce the dependence on glasses.

Myopia management options available at Eyeworks London
MiYOSMART Spectacle Lenses
It is not fully understood but under-correction of the peripheral vision reduces the progression of myopia.
Hoya optical lens manufacturers have collaborated with Hong Kong Polytechnic to develop a lens called MiYOSMART. The lens has a peripheral defocus (to reduce myopia progression) while simultaneously providing clear vision. They have called this technology DIMS (Defocus Incorporated Multiple Segments).
The MiYOSMART lens was trialled in a 2 year study where participants had an average of a 60% reduction in myopia progression. The lens is a new non invasive myopia management solution. It is safe and convenient with the same look and experience as an ordinary spectacle lens.
MiSight contact lenses
Soft contact lenses have recently been developed especially for myopia management. These contact lenses have a dual focus like multifocal lenses that create a peripheral defocus. MiSight lenses from Coopervision reduce myopia progression on average 59%. Theses lenses are a daily disposable lens and are suitable for children as young as 8.

Making Myopia Management Routine
Myopia is such a common eye condition yet Myopia Management remains a speciality in Optometry. It is usually only offered in specialised clinics in specific appointment slots. We feel Myopia Management Consultations should be offered as part of a routine eye test - so no special appointments or extra charges apply. For an appointment please call 02075842697 or book online.
