A 24year study on Refractive error determined children with 2 myopic parents were 6.42 x more likely to become myopic as children with one or no myopic parents. https://pubmed.ncbi.nlm.nih.gov/10416932/
- 4 Outdoor time
Myopia, Lifestyle and Schooling in Students of Chinese ethnicity in Singapore (having 29.1% myopic children) and Sydney (having 3.3% myopic children). Sydney children read more books per week and did more near work activities (29.93hr/week) compared to Singapore children (23.53 hr/week). Children in Sydney spent more time outdoor 13.75hr/week compared to Singapore children 3.05hr/week which was the most significant factor associated with the differences in percentage of myopia between the 2 cities.

Outdoor activity reduces percentages of myopia in children. This study followed about 1700 6year olds and about 2000 12year olds and concluded that higher time spent outdoors had less myopic prescriptions after adjustments were made for near work, parental myopia and ethnicity.

Undercorrection of myopia makes eyes prescription progress even more rather than slowing down the myopia progression. This study suggests that this under-correction stimulates eye elongation when blurry vision is present.

There are specially designed glasses that work on slowing down progression of myopia and studies were already done on a few of these lens designs. None of these lens designs are available in US at this moment. We, at Visioncare Family, will be the first ones to offer them when they become available.
- 6 Atropine Clinical Studies:
All completed studies slowed progression of myopia 50-70% depending on concentration.

- 7 Soft Dual-Focus Contact Lenses
MiSight lenses for myopia control. Three year study with 144 myopic children determined contact lenses were effective in slowing myopic prescription by 59% and slowing eye elongation by 52%. The only FDA approved contact lens for myopic management.
Multifocal Contact Lens Myopia Control. This study showed 50% reduction in progressing myopia in 40 children over a 2year treatment.
- 8 OrthoK Lenses
This review of six studies show 667 children fit with OrthoK lenses (reshaping contact lenses overnight) is significantly better at controlling eye elongation (progressing myopia) than children with glasses correction.

This study shows children fit with OrthoK lenses versus children fit with regular contact lenses progress significantly less. Ortho K children had 0.13 diopter progression versus regular soft contact lens children with 1.03 diopter progression.

- 9 Is It Safe for Kids to Wear Contact Lenses?
MiSight FDA Approval News Release
This analysis reviews 9 studies representing 1800 children determined that there were equal corneal infections in children versus adults. In the younger age range (8-11years old) this rate of infection is much lower than that of adults.
