What is the purpose of this trial?

Myopia (nearsightedness) can continue to worsen during young adulthood, increasing the risk of sight-threatening eye diseases later in life. Although dual-focus soft contacts (DFSC) lenses have been shown to slow myopia progression in children, their effectiveness in adults is not well understood. This study will compare DFSC lenses with standard single-vision soft contact (SVSC) lenses in myopic young adults aged 18 to 30 years. Participants will be randomly assigned to wear one of the two lens types for 24 months. The study will measure changes in axial length and cycloplegic refractive error to determine whether DFSC lenses slow myopia progression in young adults.
