Amblyopia, often referred to as "lazy eye," is a vision development disorder where one eye fails to achieve normal visual acuity, even with prescription glasses or contact lenses. This condition typically occurs in childhood and can result from various factors, such as strabismus (misalignment of the eyes), refractive errors (differences in vision between the eyes), or obstruction of vision in one eye. Early detection and treatment are crucial for improving vision in the affected eye. Common treatments include patching the stronger eye to encourage use of the weaker one, vision therapy, or corrective lenses. If left untreated, amblyopia can lead to permanent vision impairment.
