 in children is a highly prevalent vision condition. It is estimated that the worldwide prevalence will reach about 50% by the year 2050 with about 9.8% people affected by high myopia. If untreated, children with high myopia run increased risks of serious eye disorders like retinal detachment, myopic maculopathy, glaucoma, cataracts, etc later in life. Traditionally used single-vision spectacle lenses (SVL) correct myopia but do not slow its progression. The efforts towards spectacle-based myopia control took concrete shape when, in 2021, two novel lens designs viz. Spectacle Lenses with Highly Aspherical Lenslets (HAL) and Spectacle Lenses with Slightly Aspherical Lenslets (SAL), each with peripheral lenslets showed no effect on tested visual functions and were found to be safe for myopia control. Subsequent studies showed that while both HAL and SAL reduced the rate of myopia progression and axial elongation, HAL has better myopia control efficacy. Also, long-term use of HAL spectacles reduced the incidence of high myopia and could impact retinal steepness and symmetry. Based on evaluation of evidence, US FDA granted marketing authorisation on 25 September 2025 to Essilor Stellest eyeglass lenses for children 6 to 12 years old. The device comprises of “spectacle lenses with aspherical lenslets”. Lenses have a clear 9 mm diameter area in the centre, which is surrounded by rings of peripheral lenslets (tiny, raised dots) on the rest of the lens. The peripheral lenslets provide peripheral light defocus, which help to slow the progression of myopia. Essilor Stellest eyeglass lenses are the first eyeglass lenses shown to slow progression of myopia in children.){kind=link}
