Myopia Control

It’s not a word that most people use every day, but myopia is becoming an increasingly more common condition.

​​​​​​​Myopia, more commonly known as nearsightedness, is a condition where individuals are able to see objects that are close to them but may have difficulty distinguishing things at a distance, such as road signs or leaves on a tree. These individuals often squint at objects that are further away to try and help bring them into focus.

The reason objects are blurry in the distance with nearsightedness is because the eye becomes longer as the child grows.
When it comes to the prevalence of myopia, the statistics are staggering. In the U.S. alone, more than 40 percent of Americans have myopia and that number is increasing at an alarming rate, especially among school-aged children.

The reason for its escalation has been linked to two factors:
Genetics Children with one or two myopic parents are more likely to be myopic.
Lifestyle Children who spend more time on activities like reading or using handheld devices instead of spending time outdoors are more likely to become myopic.

Solutions to Myopia

MiSight 1 day is the first and only contact lens FDA-approved*to slow the progression of myopia in children aged 8-12 at the initiation of treatment. Children can apply the soft, daily wear, single use contact lenses to their eyes in the morning, wear them for at least 10 hours during the day, then dispose of them in the evening.

MiSight 1 day is an award-winning dual-focus soft contact lens that uses ActivControl™ Technology to slow the elongation of the eyeball.

​​​​​​​The ActivControl™ Technology in MiSight 1 day utilizes an optic zone concentric ring design with alternating vision correction and treatment zones. Two zones are vision correction zones with the label power of the contact lens, and the alternating two zones are treatment zones with 2 diopters of defocus to slow the progression of myopia. This design allows the child to see clearly while benefiting from the treatment effect.

What causes myopic progression?

Genetics, environment, and optics error of the eye are contributing factors for myopic progression.

Myopic progression is due to axial elongation of the eyeball. As the eyeball gets longer, the amount of nearsightness increases (i.e. the nearsightness prescription increases and lenses from eyeglasses become thicker)

Traditionally, spectacle and monofocal contacts lenses (non-bifocal/non-multifocal) are used to correct myopia; however, they do not help slow down the progression of myopia.

​​​​​​​Research has shown that peripheral hyperopic defocus caused by regular spectacle lenses and monofocal (single vision) lenses is a contributing factor for elongation of the eyeball. Peripheral hyperopic defocus is defined as the images formed behind the peripheral retina from the light rays refracted from the edges of the spectacle lens or contact lenses.
