Millions of patients around the world wear contact lenses to correct their vision.1In fact, research suggests that contact lenses provide patients with benefits such as better perceived cosmetic appearance, better social acceptance, and a better ability to play sports compared to glasses.2-4While most contact lens wearers use soft contact lenses for cosmetic reasons, some patients wear specialty hard contact lenses because they are the only way that they can achieve functional vision without undergoing surgery to correct a visually debilitating eye disease like keratoconus (a degenerative disease that results in an irregularly shaped cornea).5In other cases, patients who suffer from moderate to severe dry eyes wear specialty contact lenses because they have the ability to make their eyes comfortable enough to effectively function.6While there is more than one type of specialty contact lens that can help patients with these conditions, scleral lenses have emerged over the past few years as the contact lens treatment of choice for these difficult-to-treat patients.7
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
