Controllo della Miopia
Myopia prevalence is 40% in Europe and North America. However, it is significantly higher in Asia where prevalence is reported to be as much as 90%. Childhood myopia usually develops between the age of 6 to 16. Early detection of myopia is important as poor distance vision can affect a child's education and development. Although spectacles and regular contact lenses improve vision, they do not slow down the progression of myopia. As a result, frequent prescription changes are required to maintain clear vision. Research has identified a possible cause for the progression of myopia. The peripheral hyperopia theory relates the focus of the peripheral image to eye growth and therefore myopia progression. Myopia control therapy uses special contact lenses to alter peripheral light focus to reduced myopia progression. These contact lenses have been shown to achieve up to 50% reduction in myopia progression compared to spectacles. It's generally best to start therapy during early myopia until the age of 16. Ask your practitioner about myopia control therapy if your child has myopia.
