Optics
ActivControl Technology. Two treatment zones create myopic defocus with image focus in front of the retina rather than behind it, and two correction zones correct myopia in all gaze positions.
Geometry
Aspheric, the two zone types laid out as alternating concentric rings: a correction center, then a treatment ring, a correction ring and a treatment ring outward.
Study
Over three years myopia progression fell 59% against a single vision 1 day lens, with a 52% reduction in average axial lengthening; the MiSight arm carried n=116 at 12 months, n=110 at 24 and n=104 at 36.
Indication
Correction of myopic ametropia and slowing of myopia progression in children with non-diseased eyes, 8-12 years of age at initiation of treatment, with a refraction of -0.75 to -4.00 diopters spherical equivalent and 0.75 diopters or less of astigmatism.
