Myopia Management
What is Myopia?
Myopia is an eye condition, also known as short-sightedness or near-sightedness, which causes people to have difficulty seeing distant objects clearly. Children will struggle to see the board at school, or the TV or perform less well in sports activities due to not being able to see distant objects as clearly as they should. Myopia is usually progressive and as a result changes occur in the physical structure of the eye, elongating it. These changes, especially in individuals with high levels of myopia, can significantly increase the risk of retinal detachment, myopic maculopathy, cataracts and glaucoma, in turn leading to vision loss and blindness.
'Short-sightedness' or 'nearsightedness' are the common terms for myopia - a common eye condition that makes distance vision blurry. It usually starts in childhood and gets progressively worse until the child stops growing.

Myopia incidence and levels of myopia are increasing worldwide, especially in East Asia with reports of 90% of Chinese teenagers and young adults being myopic. It is becoming a worrying public health issue.
It is estimated that by 2050 half of the world’s population will be myopic. ²Although there is no cure or quick fix for stopping myopia progression completely, it can now be slowed down several ways, resulting in a child being less myopic, with less potential for complications, associated with high myopia. The earlier treatment is started the better the results.

MiSight contact lens has
- two treatment zones, creating myopic defocus in the periphery and
- two correction zones, correcting the myopia in all gaze positions, to ensure clear vision.
They are worn for a minimum of 10 hours a day, 6+ days per week, with a new pair being inserted each day. It is a commitment to wear lenses daily and is not available on the NHS. It is available on a planned monthly payment scheme, including all professional examination and fitting fees. Fitting is recommended as early as possible, when myopia first presents.
These lenses only cost a few more pounds than conventional soft contact lenses, which will not slow down the myopia progression. The fitting is charged at the same rate as for normal lenses.
NaturalVue Contact Lenses
NaturalVue Multifocal 1 Day contact lenses are clinically effective for myopia progression control and are an excellent option in slowing the progression of myopia in children. We have been using this lens with success within our Myopia Management Clinic since the lens launched in the UK in early 2019. Whilst initially being designed for use in over 45-year-olds suffering from presbyopia (the need for reading glasses or varifocals), NaturalVue has impressive myopia management credentials.

In September 2020, Visioneering Technologies Inc. (VTI), maker of the NaturalVue (etafilcon A) Multifocal 1 Day Contact Lenses presented exciting data at the Global Myopia Symposium. The 5-year study showed a consistent reduction in rates of myopia as well as a reduction in axial length with prolonged wear of NaturalVue contact lenses.
Unlike single vision or traditional multifocal lens designs, the Neurofocus Optics® design in NaturalVue® creates an extended depth of focus, enabling nearly 2 x the range of clear vision (up to 76cm) vs. Best corrected spectacle refraction, allows for better, nearly seamless vision at all distances and wearers experiences statistically significantly improved stereo acuity compared to leading lenses tested.

The science of Neurofocus NaturalVue® Multifocal 1 Day Contact Lenses are designed with a high amount of relative plus power in the periphery. This uninterrupted plus power progression induces peripheral blur in the brain.
MiYOSMART Spectacle Lenses
In 2012 Hoya worked with The Hong Kong Polytechnic University to develop a technology to slow down myopia progression using the defocus theory, the Defocus Incorporated Multiple Segments (D.I.M.S).
In a 2 year clinical wearer trial it proved to:
- Slow down myopia progression by 59%
- Reduce axial elongation by 60%.4
MiYOSMART is non invasive and easy to fit like a regular spectacle lens.
The lens corrects the visual defect on its entire surface and has a ring shaped treatment area to slow down myopia progression. The alternation of the focus area and defocus area provides clear vision and manages myopia simultaneously.
It comes with an easy-to-wipe special anti-reflective, durable coating. With its Eye Shield, young patients get the added assurance of an impact resistant material and UV protection.
We are also suppliers of MyCon lenses from Rodenstock.
With MyCon lenses, light is diffused so that it strikes the periphery in front of the retina rather than behind it. This slows eye-length growth. The areas that control myopia progression in a MyCon lens are located laterally. This ensures that the visual acuity above and below is affected as little as possible.

Superb Service!
Went in for an enhanced eye test this afternoon and was nervous about cataracts. Helen did the scans and made me feel at ease. Cathy carried out the important bit, and was absolutely super, why did I ever worry? Thank you Cathy, huge sigh of relief !!! Just needed a pair of driving spectacles, and was looked after brilliantly by Jack. Thank you all for a great; and relaxing, visit.
