Intervention - Correction
Children with shortsightedness need to be fully corrected. No scientific reported undercorrection can slow down myopia progression. On contrary, undercorrection may induced a small but insignificant increase in myopia progression compared to full correction18, 19.
Intervention - Myopia Control
MiSight™ is one of the options for myopia control available in the market.
MiSight™ : A Daily Disposable Contact Lens
Key benefits
-
One day contact lens: free from complicated cleansing procedure
-
Lens made of Proclear® material: effective in locking in moisture and providing more than sufficient oxygen for daily wear
-
Correct shortsightedness (nearsighted) while help reduce the progression of myopia

MiSight™ - ActivControl™ Technology
ActivControl™ Technology combines two optical systems that provide:
-
Clear Distance, Intermediate and Near Vision
-
Treatment Zones that can slow down the rate of progression of myopia
What is ActivControl™ Technology
A technology that delivers dual optical properties
-
an optic for vision correction and
-
an optic to control myopia progression

ActivControl™ Technology creates myopia defocus to control myopia progression.

Myopia defocus treatment effect: Distribution
Efficacy - Myopia progression21:
-
Average reduction was 0.30D/yr (p<0.01)
-
75% of the treatment eyes received ≥ 30% reduction in myopia progression
-
20% of the treatment eyes stopped myopic progression

Myopia defocus treatment effect: Eyeball length
-
Eye growth responses to the myopic retinal defocus treatment at commencement (Slope A)
-
Once the lens wear is discontinued, the eye will progress with its normal rate (Slope B)
-
However, the treatment effect already received will remain20 and did not develop into slope of C
