A recent study predicted that by the year 2050 half of the world’s population will be classified as myopic, or near-sighted. Of that portion of the population, 10% will develop myopia of 5.00D (diopters) or stronger. With that in mind, research has been ongoing into ways to manage, mitigate and minimize the effects of myopia, particularly in children if caught early enough.
In 2012, Hoya Vision Care partnered with the Hong Kong Polytechnic University, a leader in the field of myopia control research, to develop a new type of ophthalmic lens to better control developing myopia. The result of their combined efforts is the MiyoSmart lens.
What is MiyoSmart?
D.I.M.S stands for Defocus Incorporated Multiple Segments. The front of the lens has a small central zone that carries the patient’s full corrective prescription. Surrounding this zone are evenly placed smaller circular zones or “islands” of defocus, where the measured prescription is significantly weaker than the full myopic correction. This allows the patient to look through a lens that is both focused and defocused at the same time regardless of viewing distance.
But how does a lens with defocused segments improve myopic progression?
How Does MiyoSmart Work?
With the D.I.M.S areas of defocus, MiyoSmart lenses simultaneously allow light to land both on the retina and in front of the retina. This encourages the eye to slow or halt the elongation reflex that would otherwise occur while still providing clear vision. For this type of therapy to effectively manage myopia progression it must be a continuous effect, hence the need for corrective lenses to be worn full time.
But how can functional, clear vision be achieved when parts of the lens are made with a weaker prescription? This is where the lens relies on another reflex of the brain, and its tendency to only focus on the clear inputs it receives and block out much of the blur. The ratio of full prescription power and weakened prescription is 50:50, a ratio that has been thoroughly tested and verified to provide comfortable vision for the wearer.
Why Choose MiyoSmart?
The lenses are made of polycarbonate, an impact resistant material great for protecting the eyes of even the most rough-and-tumble kids. At the same time, polycarbonate lenses are thin and lightweight, perfect for stronger myopic prescriptions that tend to produce thicker lenses. Every MiyoSmart lens is made with UV protection, scratch-resistant and anti-reflective coatings.
What Can Parents Expect from MiyoSmart?
It is expected to have a follow up visit with the Optometrist 2 weeks after the initial fitting and dispensing of the MiyoSmart glasses to evaluate adaptation and performance. After that, the child will be seen by the Optometrist every six months for regular myopia progression monitoring.
