Myopia is an ophthalmic condition where distant objects do not appear clearly. It is due to the elongation of the eyeball. It usually develops during childhood or adolescence, and myopia can be corrected using eyeglasses or contact lenses. The condition is often diagnosed through routine eye exams. Factors contributing to myopia include genetics, excessive close-up work, and possibly limited outdoor activity. In recent years, myopia has become increasingly common globally, prompting ongoing research into its causes and potential preventive strategies. While myopia is generally not harmful, high degrees of it can increase the risk of other eye conditions like retinal detachment, glaucoma, and cataracts later in life.
