It is expected that myopia progression stabilises in the late teenage years, however, some studies report that myopia progression continues through early adulthood in as many as one third of myopes. Similarly, there are reports of myopia commencing in early adulthood. Although the rate of progression is slower than that occurring in childhood, between 20-35% of adults aged between 20-30 years were reported to progress by at least -1.00D over a five year period. Given that every dioptre increase in myopia results in an increased overall lifetime risk of serious ocular pathology, it seems opportune to investigate whether myopia management treatments designed to slow myopia progression in childhood could be beneficial for progressing adult myopes. The proposed study will conduct a prospective, randomised, paired-eye, trial with cross-over to evaluate the efficacy of Essilor Stellest myopia management spectacle lenses on the progression of myopia in adults aged between 18-40 years. The outcomes from the trial will provide novel evidence regarding the utility of these lenses in an adult population.
