What is myopia?
Myopia is a condition that results in distant objects appearing blurry to a patient when not being corrected with glasses or contact lenses.1 Myopic blur typically results from the eye being too long for its optical focusing components (cornea and crystalline lens), which causes distant objects to be in focus in front of the retina (back of the eye) instead on the retina, a requirement for the eye to be able to see clearly.1 About one third of Americans have myopia, and its prevalence is likely increasing because of factors associated with living in a developed country (e.g., decreased time outdoors).2-5 With that said, the scientific community only has a vague understanding of how genetics and the environment influence the development and progression of myopia.1 While myopia’s visual affects can be a costly nuisance and strain on the health care system,6 myopia also places the affected individuals at a greater risk for developing vision-threatening conditions like cataracts, retinal detachments, and glaucoma.1 Once present, myopia cannot be cured; therefore, preventing it or even reducing the amount of myopia that a patient develops is an upmost priority for the scientific community.7
