Nearsightedness Control

Zeiss MyoVision nearsightedness myopia controlAt Fremont Eye Centre, we offer different options for nearsightedness control. Dynamic lenses by Hoya, MyoVision lenses by Zeiss, bifocal lenses and multifocal contact lens are good alternatives to orthokeratology (ortho-K) to reduce nearsighted progression in children.

What is nearsightedness (or myopia)?

Nearsightedness is the most common refractive error of the eyes making distance vision blurry. It is common in children especially when they are growing. When the eyeballs become longer, it creates a mismatch between the refractive power of the eye and the length of the eyeball.

Dynamic Lenses

MyoVision™ Lenses

zeiss optical labSimilar to Dynamic lenses, MyoVision™ lenses are specialized lenses mounted on an eyeglasses frame. They are worn for all visual activities including reading and distance vision. Research has shown that MyoVision™ lenses reduce progression of myopia by an average of 30% in children from age of 6 to 16 with at least one nearsighted parent.

Bifocal Lenses

Similar to Dynamic lenses, Bifocal lenses are a combination of reading glasses and distance glasses. The upper portion of the glasses contains distance power while the lower portion contains reading power. By relaxing the eyes through the reading portion, we slow down progression of nearsightedness by minimizing eyeball elongation.

Advantages of Dynamic/MyoVision/Bifocal over ortho-K:

  • NO hard contact lens to be worn while sleeping
  • NO risk of infection of the eyes associated with contact lens wear
  • NO risk of scarring and injury to cornea associated with contact lens
  • NO expensive consultation fee
  • Able to correct for significant amount of myopia and astigmatism

Multifocal Contact Lens

Multifocal soft contact lenses are usually used for people older than 40 who have presbyopia or reading problems. It has been shown that multifocal soft contact lenses slows down myopia progression by around 50% in several studies. Although your child would be wearing contact lens, the risk of the eye infection is significant less than overnight hard contact lens wear like ortho-k.
