What is myopia?

Myopia is a very common eye health condition. Often called “short-sighted,” a child with myopia can see clearly up close but has blurry vision when looking at objects in the distance—like a smartboard.

Myopia happens when the normal eye grows too long from front to back. 

Light rays have trouble reaching the right spot on the back of the eye (the retina) to achieve clear distance vision.

It’s more than just stronger, thicker glasses. Myopia in kids can get worse as they grow, increasing the risk of serious eye conditions.

What causes myopia?

  • Myopia can be inherited from one generation to the next. If mum or dad wears glasses, chances are their child will too.1
  • Lack of time spent outdoors in the sun has been linked to the development of myopia.1, 2,3
  • Spending more time reading close-up on digital devices may also contribute to a child’s myopia.2,3,4
  • And there’s the routine correction of myopia – resulting in Peripheral Hyperopia – that has also been shown to signal the eye to grow, thus causing myopia.2

What are the eye health risks?

The number of kids with myopia is growing at an alarming rate around the world.  The younger your child develops myopia, the greater the risk of serious eye conditions like retinal detachment, glaucoma, cataracts, and even blindness.5

Beyond the eye health risks, myopia can negatively impact your child’s performance in school and other activities.

There is NO SAFE level of myopia.5  Practitioners and researchers do not know which child will progress to what degree.  Each prescription (diopter) increase can have a significant impact and the impact can occur anywhere – in low to high myopia ranges.6   Earlier intervention may be ideal, but any intervention is a potential benefit.   If we can reduce the level of progression, data suggests that the impact could be significant:

  • 20% reduction in retinal detachment, cataracts, glaucoma, and overall visual impairment.6
  • 40% reduction in macular degeneration. 6

This means – ½ to nearly 1 year of visual impairment could be saved. 6

What are some evidence-based ways to slow down myopia progression?

Your eye care practitioners may be able to help slow or control your child’s myopia with specially designed glasses, eye drops, or contact lenses. All of these solutions have been shown to have various levels of effectiveness.  Talk to your eye care practitioner for more information like how each works, effectiveness rates, benefits, and limitations. 

  • Specially Designed Eyeglasses
  • Pharmaceutical Eye Drops (Atropine)
  • Specialty Contact Lenses
    • Hard contact lenses (or Orthokeratology or Ortho-K lenses) that physically re-shape the cornea at night during sleep.
    • Soft multifocal contact lenses like NaturalVue® Multifocal 1 Day Contact Lenses. 
      • NaturalVue Multifocal 1 Day soft contact lenses, by comparison, utilize patented optics to move the light rays inside the retina so that the signal for the eye to grow and elongate is reduced (addressing Peripheral Hyperopia). 16,17
      • These lenses provide excellent vision by day.18
      • These lenses are daily disposables, which means comfortable daily wear with no cleaning or maintenance.
      • Clinically effective for myopia progression control.19  
        • 98% of children showed a decrease in myopia progression19
        • 81% of children’s progression stopped completely, with some showing reversal. 19
        • 0.82D average dioptric decrease per year in children ages 6-1919*
