  • levels of myopia
  • There are hints from these studies and predictions based on the presumed mechanism for control with ortho-K that the resulting effect is less for lower levels of myopia and greater for higher levels of myopia. (healio.com)
  • Individual practitioners may find better control than the studies suggest, perhaps due to the particular design used or, perhaps in the case of ortho-K, due to the particular mix of refractive errors treated, with higher levels of myopia showing greater control than the averages in the clinical trials. (healio.com)
  • Available on the Google Play Store, Myappia is intended primarily for optometrists, ophthalmologists and pediatricians to help them identify patients at risk for myopia, explain those risks and demonstrate the predicted effects of slowing their myopia progression using different methods with various expected levels of myopia control.

  • Because more people, including children, are developing high myopia, various methods of attempting to slow its progression have been attempted. (aapos.org)

  • Investigators noted that longer exposure to moderate sunlight intensity (i.e., hallways, under trees) was as effective as short exposure to high sunlight intensity for preventing myopia. (aao.org)
  • child's
  • If you suspect your child has myopia, you should take them to an ophthalmologist or optician to have their eyes checked, because untreated myopia can compromise quality of life and your child's development. (zeiss.com)
  • Since the progression of myopia can lead to a higher risk of other eye problems, a child's eyes should be tested regularly to identify harmful changes early on - at least once per year, but ideally every six months. (zeiss.com)
  • In general more indoor activities and consequently the lack of natural light are part of a contemporary lifestyle that can increase a child's myopia. (zeiss.com)
  • genes
  • Evaluating more than 250,000 participants across North America, Europe and Asia, the study identified 161 genes related to myopia whereas it had only found nine the year before in a smaller meta-analysis. (aoa.org)
