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.
For children who would develop high levels of nearsightedness, slowing down the progression could mean a lower prescription giving clearer vision, thinner glasses lenses and more options with contact lens wear. In addition to lower prescription, it also yields a lower incidence of retinal detachment, myopic macular degeneration, cataracts and glaucoma, all of which are associated with high level of nearsightedness.
Orthokeratology, also known as corneal reshaping therapy, is a specialty contact lens fitting using a gas permeable contact lenses worn overnight to change the corneal curvature, thus modifying the cornea’s refractive power. Combining its unique advantage of providing clear unaided vision during daytime, orthokeratology induces an effective peripheral power profile that control eye growth and hence controlling nearsightedness. Orthokeratology has become one of the most popular and effective choices among children for nearsightedness control.

MiyoSmart is an innovative spectacle lens for myopia control developed by Hoya together with its research collaborator. Based on a two-year clinical trial results, MiyoSmart is proven to curb myopia progression in children in average by 60% with its award-winning D.I.M.S. (Defocus Incorporated Multiple Segments) technology. Worn like a pair of regular glasses, MiyoSmart is a safe non-invasive way to control nearsightedness.

Developed by Cooper Vision, MiSight is a soft daily disposable contact lenses worn during daytime. Not only does it optically correct existing myopia (not astigmatism), giving clear distance and near vision, but MiSight has also been proven to slow the progression of myopia in most children.
