Why is Myopia Control important?
Myopia, or short-sightedness, is where the eyeball is too long, resulting in blurry vision in the distance. Usually, once you have myopia, especially at a young age, it tends to worsen over time. With each degree of increased myopia, your risks of eye diseases such as myopic maculopathy and retinal detachment increases few folds compared to those without myopia. Therefore it is important to prevent or reduce the progression rate as early as possible.

Why are the options for Myopia Control?
There are multiple methods of myopia control available! Some are more effective than others depending on each individual. These include:
Orthokeratology involves wearing a hard contact lens overnight. This process over time gently reshapes the cornea so that clear vision can be attained with no correction required during the day.
Studies have shown that this is one of the best myopia control methods available. Prescribing and using this lens will depend on the shape of the your cornea, as well as your myopia degree.
MiyoSmart Spectacle Lenses
The Hoya MiyoSmart spectacle lens is a specialty lens designed with the patented Defocus Incorporated Multiple Segments (D.I.M.S.) Technology. In randomised clinical trials, it showed a 60% reduction in myopia progression over 2 years for children 8-13 years old.
The lens features hyperopic defocus circlets around a 9mm central clear zone, making this lens very easy to wear. It is made in a tough polycarbonate material, perfect for children. And it also accommodates prescriptions up to -10.00DS and astigmatisms <4.00, therefore nearly available for everyone!
Frame selection is critical in successful wear. You will be guided by one of our qualified optical dispenser in choosing and fitting the lenses.
MiSight® 1 Day Contact Lenses
MiSight® 1 Day soft contact lenses are convenient, effective way of both correcting vision and reducing progression of myopia. As these are soft, daily lenses, they are very comfortable and the risks of contact lens infections are reduced compared to reusable contact lenses. These are available for prescriptions from -0.25 to -6.00.
Atropine eye drops
Low dose atropine has been shown to reduce the progression of myopia. These eyedrops need to be used in conjunctiva with either spectacles of contact lenses as they have no visually corrective ability. These eye drops are not yet commercially available in Australia. There are no compounding pharmacies capable of producing these eye drops in Canberra, so will need to be made in other states and delivered to you.
Multifocal Soft Contact Lenses
Certain designs of multifocal and extended depth of focus soft contact lenses have shown promising results in reducing myopia progression. For patients with myopic prescriptions outside of the range of orthokeratology and/or MiSight® and would still like to wear contact lenses for myopia control, we have a range of daily and monthly soft contact lenses available.
Multifocal/Bifocal Spectacle Lenses
Multifocal or bifocals have shown efficacy in reducing myopia progression. Prescribing theses lenses will depend on how your eyes work together, which we will be able to assess with your comprehensive eye examination.
What can I do to prevent myopia?
There are environmental changes that can help prevent the onset of myopia. These include:
- Spend <2 hours on the screen after school.
- 20/20 rule: Every 20 minutes of near work, take a break for 20 seconds and look in the distance.
- Don’t hold things too close when reading! Keep a forearm distance between eyes and book/screen.
- Spend more time outdoors being active. Remember to be sun safe!
