myopia Control with Misight
What is Myopia?
Myopia (or nearsightedness) is the inability to see distant objects clearly. Nearsighted individuals see better near than far. Myopia is often the result of an elongated eye, or longer axial length on average, that inaccurately focuses light in front of, rather than, on the retina. The retina is the photographic film at the back of the eye. So why is myopia a problem, besides having to wear vision correction? Higher levels of myopia are associated with a higher risk of eye disease. Longer eyes are more susceptible to the following diseases that can cause vision loss:
The optics of myopia are seen below. Distant objects such as street signs or presentation boards are blurred.
What are the risk factors for myopia?
Parental myopia, myopic siblings, Asian ancestry, myopia that appears before the age of 7, rigorous academic pursuits (high near visual demands) particularly at younger ages, and limited outdoor activity all can be used to predict myopia and its progression to high myopia. Patients with high degrees of myopia experience a poorer quality of life than those with low to moderate myopia. Refractive surgery can also be affected, with outcomes generally better in patients with lower prescriptions. Myopia control therapy can help change the future of your child’s myopia progression and significantly reduce the risk of future visual impairment.
MiSight – D.O.T. Technology for Myopia Control
This spectacle lens type is made up of a central clear optical zone for correcting myopia, with an outer band of defocus that acts to control myopia progression. The lens makes use of the natural eye adjustment known as “emmetropisation”, where the eyeball shapes to receive focused images as it does for normal vision. The MiSight lens design, distributed in Canada through select eye care professionals by Coopervision, was found to slow down myopia progression by 59% on average, compared to single vision lenses, when worn 12 hours a day*.
– Curbs myopia progression on average by 59%
– Slows axial eye growth
– for children 6 and up
– save 30% on a second spare pair
Below is an image of the MiSight lens for Myopia Control.
MiSight Spectacle Lenses are powered by Diffusion Optics Technology and are clinically shown to slow the progression of myopia in children as young as 6 years old. These lenses use a unique technology that helps scatter light to reduce retinal contrast. High contrast light is believed to stimulate excessive eye growth and worsen myopia (nearsightedness). The Cypress Study followed children over a 2-year period wearing MiSight Spectacle Lenses full time. The lenses were shown to slow the progression of myopia by 59%. These lenses are intended to be worn full-time (12 hours a day).
Who is a candidate for MiSight spectacles?
Children 6 and up who have myopia and can wear glasses full time.
What is unique about this lens?
It uses a novel technology called Diffusion Optics Technology (D.O.T.) and has a wide prescription availability. It is made of a durable and light material called Trivex, which has superior optical quality, yet equivalent safety features when compared to polycarbonate lens material. It also offers inherent UV protection.
These lenses have equal adaptation and acceptance to standard single-vision lenses, with the benefit of slowing myopia progression in children. They offer a wide treatment zone while allowing for clear, crisp vision, even when viewed from the periphery. In addition to providing sharp vision as a standard single vision, the optics create a signal in the child’s eye acting as a shield against eye elongation.
Thanks to the D.O.T.* technology, these lenses slow down myopia progression by 59% on average, compared to single vision lenses, when worn 12 hours a day.*
Myopia Control Therapy is an investment in your child’s future eye health and well-being. With increased screen time at the expense of outdoor activities, myopia is growing at epidemic proportions. By 2050, half the world’s population, or 5 billion people, will be myopic. Several treatment options exist that have been found to diminish the eye’s axial lengthening and the corresponding myopia progression. After conducting a thorough vision and eye health assessment, Dr. Sciberras will determine the modalities best suited for successful compliance and myopia control. At times, more than one viable option exists, and the decision will be made after deliberate consultation between the doctor and parents. We are 100 percent committed to providing you with the best value in eye care and eyewear. We strive to provide all patients with clear, comfortable vision with the best lens technology and the most convenient modality for your child. We have an obligation to make the science and research available to you to ensure long-term eye health for your child.
Early intervention through regular eye exams and myopia control therapy is the best way to maintain healthy eyes and vision preservation for your child.

Sign up for the Myopia App – this ingenious digital device app measures how closely the device is being held and darkens the screen if it’s held too close, revealing the screen again when it’s held back at the ideal distance or further. Developed by a partnership of scientists and optometrists, early research on this app has shown it effectively modifies screen time behavior, making a dramatically positive difference in the demand placed on the eyes.

A Word About Astigmatism
Astigmatism can accompany nearsightedness. It is the result of an eye that is shaped like a football. It causes light to be focused at two distances within the eye, instead of one. The one place light should be focused to have clear vision is the retina. Astigmatism can cause blurred vision at near and far distances. This can result in headaches, eyestrain, and squinting. Astigmatism can be corrected with either glasses or contact lenses.
Vision is a gift and should never be taken for granted. Dr. Sciberras can detect eye disease in the absence of symptoms and can determine risk factors for future eye disease. Some of the symptoms your child may display in the presence of myopia include frequent eye rubbing, squinting, sitting closer than normal for reading and viewing tasks, turning their head to the side, complaints of tired eyes, or inability to recognize signs or people from a distance.
Recommended Screen Time
- 0-2 years of age should have no screen time. Watching a screen at a young age can limit time for active play and learning, reduce opportunities for language development and inhibit their attention skills.
- Children aged 2-5 years should have a maximum of 1 hour per day. Infants, toddlers and pre-schoolers should not be inactive or sedentary for more than one hour at a time, except for sleeping. In this age group, excessive screen time is associated with less outdoor, creative and active play time; poorer language skill development; poor social skills and an increased risk of obesity.
- Children of school age (5-17 years) should be limited to 2 hours of recreational screen time per day. When using screen-based electronics, positive social interaction and experiences are encouraged. Sleep is also so important in this age group. Children aged 5-13 years should have an uninterrupted 9 to 11 hours of sleep per night and 8 to 10 hours per night for those aged 14–17 years. Consistent bed and wake-up times are very helpful, as are restricting screen time 2 hours before bed and removing screens from the bedroom where possible.
- Apply the 20-20 Rule: take a break from reading or screen time every 20 minutes for 20 seconds looking at something far away (say 20 feet). He or she should look across the room to relax the focusing muscles in the eyes before commencing near viewing. Closing your eyes for another 20 seconds could go a long way to relieving dry eye symptoms.
