Myopia

Nearsightedness

Myopia, also known as nearsightedness, is a common vision condition where close objects are seen clearly, but distant objects appear blurry. This occurs when the eyeball is slightly too long, or the cornea is too curved, causing light entering the eye to focus in front of the retina instead of directly on it.

Causes:

Genetics: Myopia often runs in families, suggesting a hereditary component.
Environmental Factors: Activities that involve prolonged close-up work, such as reading or using computers, may contribute to the development of myopia.
Lack of Outdoor Time: Some studies suggest that spending less time outdoors during childhood may increase the risk of developing myopia.

Symptoms:

Blurred vision when looking at distant objects.
Need to squint to see clearly.
Eye strain or headaches.
Difficulty seeing while driving, especially at night.

Diagnosis:

Myopia is usually diagnosed through a comprehensive eye examination, which includes tests to measure visual acuity, refraction, and the structure of the eye.

Treatment:

Eyeglasses or Contact Lenses: The most common and simplest treatment, which corrects the refractive error.
Refractive Surgery: Procedures like LASIK or PRK can permanently correct myopia by reshaping the cornea.
Orthokeratology: Special contact lenses worn overnight to temporarily reshape the cornea.
Atropine Eye Drops: Low-dose atropine drops may slow the progression of myopia in children.

Prevention:

Encourage children to spend more time outdoors.
Limit screen time and close-up activities.
Regular eye check-ups to detect and manage myopia early.

Myopia is increasingly prevalent worldwide, especially in urban areas. Early detection and management can help prevent complications and maintain good vision quality.
