New Myopia Control for Kids
– The Myovision Lens by Zeiss
Myopia, also called nearsightedness, is common in Asian children especially with parents also having myopia. Typically myopia is first diagnosed between the ages of 4 and 6; after that an annual progression of 0.60D to 1.00D in young children is quite common among the Chinese population. Over 50% of 11-13 year old children living in urban Asia have myopia.
Zeiss offers a new lens technology called Myovision. It is the first single vision lens design of its kind in the world and just came to Canada in Spring 2011. This new invention uses Peripheral Vision Management technology which brings the peripheral image forward, onto or even in front of the retina while independently positioning the cental image on the retina to give clear vision. By moving the peripheral image forward, this removes the stimulus to myopia progression. I.e. Stop signal to the eye to control eye elongation.
Myopia incidence has doubled in about 30 years and is a major problem in Asia, where it affects more than one billion people. A study done in Sun Yat Sen University in China from Oct 2007 to Jan 2009 with 210 myopic Chinese children aged 6 to 12 years old resulted in reducing myopia progression by an average of 30% when at least one parent was also myopic. There is an additional study underway with non-Asian children.
People who spend more time outdoors in the sunshine also have lower incidence of myopia. Studies in China show that the rate of myopia in the summer is half of that in winter months. Also in Sydney Australia, a study found that the risk of myopia could be reduced substantially when children spent more time outdoors.
This may be related to increased secretion of dopamine (a neurotransmitter found in the retina) when extended time is spent outdoors, the lengthening of the eye could be slowed.
Research is continually being done on myopia control. It is best to find out what is the best treatment on an individual basis by your optometrist.
