These lenses are typically worn during the day and need to be replaced regularly.

MiSight is a specific brand of soft daily disposable contact lenses designed for myopia control in children.

These lenses have a dual-focus design, with the central part correcting distance vision and the outer part designed to reduce the stimulus for myopia progression.

MiSight lenses are worn during the day and discarded daily.
