What does it mean to have myopia?
I have been experiencing increasingly blurry vision lately, especially when looking at distant objects. I can only see clearly when I get very close. People around me say I might have myopia, but I don't quite understand it. I'd like to know—what exactly does it mean to have myopia?
Myopia, medically referred to as "nearsightedness" or "myopic refractive error," is a common vision problem. Its main characteristics include an elongated anterior-posterior axis of the eyeball or excessive refractive power of the cornea and lens, causing light from distant objects to focus in front of the retina rather than directly on it.
The development of myopia is associated with multiple factors, including genetics, environmental influences, and不良 eye habits. Genetic factors play a significant role in the development of myopia, especially high myopia. Environmental factors such as prolonged near-eye work, insufficient or excessive lighting, and incorrect posture while using the eyes can also increase the risk of myopia.
Treatment options for myopia include wearing glasses, contact lenses, or undergoing laser refractive surgery (such as LASIK, LASEK, etc.). In recent years, methods to control the progression of myopia in children and adolescents have also been developed, such as specially designed multifocal contact lenses, orthokeratology lenses, and low-concentration atropine eye drops.
To correct vision in patients with myopia and improve visual quality, methods such as wearing eyeglasses, contact lenses, or undergoing refractive surgery can be employed. If discomfort occurs, prompt medical attention is recommended.
