High myopia, also known as severe nearsightedness, is a vision condition in which individuals have a refractive error of -6.00 diopters or more. High myopia is a condition that makes faraway things look blurry, but close things look clear. This condition happens when the eyeball grows too long from front to back, which causes light rays to focus in front of the retina rather than directly on it. This condition can develop gradually or rapidly, often during childhood or adolescence, and tends to stabilize in early adulthood. High myopia increases the risk of several eye-related complications, including retinal detachment, glaucoma, and cataracts, making regular eye examinations crucial for the early detection and management of these potential issues. Advances in corrective lenses and surgical options, like LASIK and lens implants, could effectively correct vision in individuals with high myopia.
