CooperVision Canada announced that its MiSight 1 day contact lenses will be available in higher prescriptions. The full expanded range—covering -0.25D to -10.00D (0.50D steps after -6.00D)— means that MiSight 1 day covers 99.97% of prescriptions for age-appropriate children – who have myopia and less than 1D of astigmatism.[1] The diopter extension for this innovative, specially designed lens will allow even more children to benefit from myopia management.
MiSight 1 day contact lenses are backed by the longest-running soft contact lens study among children. The clinical trial has proven that MiSight 1 day works for nearly all children with myopia,[2]† cuts myopia progression by half,[3]§ works at any age a child starts treatment (8+),3║ works for as long as the child wears them3║ and data indicates that there is no rebound effect with MiSight 1 day contact lenses.[4],[5]¶
With myopia on the rise globally,[6] an increasing number of children may require the higher prescriptions that MiSight 1 day lenses will offer.
“Every diopter matters, particularly for children whose myopia progression may have already placed them at a higher risk for conditions such as myopic maculopathy and glaucoma.[7] While early treatment is best, it’s never too late to start,” said Enrique Contreras, Country Manager, CooperVision Canada, “Even older children starting with MiSight 1 day have seen their myopia progression cut by half.”3§
As a global leader in myopia control* and management for children, CooperVision believes that options must be available for as many children as possible. With MiSight 1 day’s additional range extension, eye care professionals in Canada can have even greater impact.

*USA Indications for Use: MiSight 1 Day (omafilcon A) Soft (Hydrophilic) Contact Lenses for daily wear are indicated for the correction of myopic ametropia and for slowing the progression of myopia in children with non-diseased eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 to -4.00 diopters (spherical equivalent) with ≤ 0.75 diopters of astigmatism. The lens is to be discarded after each removal. Canadian Indications for Use: MiSight (omafilcon A) Soft Contact Lenses for Myopia Control may reduce the rate of myopia progression in children (6-18) and correct ametropia. Reduction of myopia progression was observed in children with wearing time of 12 hours (8-16 hours) per day, 6.4 days (5-7) per week in a clinical study. Permanent myopia control after lens treatment is discontinued is not supported by clinical studies. MiSight (omafilcon A) Soft Contact Lenses for Myopia Control are indicated for single use daily disposable wear. When prescribed for daily disposable wear, the lens is to be discarded after each removal.
†90% of myopic eyes respond to MiSight 1 day treatment; ages 11-15 at start of wear, n=90.
§Using measured and modeled data, pooled across ages (8-17), MiSight 1 day slowed myopia progression by an average of approximately 50%.
║Children with myopia fit with MiSight 1 day contact lenses ages 8-15 continued to experience slowed myopia progression as long as they remained in treatment.
¶ On average, for children aged 8-15 at start of wear. Instead, eye growth reverted to expected, age average myopic progression rates.
