Likinäköisyydessä

Likinäköisyydessä, known more commonly by its scientific term myopia, is a refractive error of the eye where distant objects appear blurry. This occurs because the eye focuses images in front of the retina, rather than directly on it. The eyeball is typically too long or the cornea is too curved, causing this misalignment of focus.

The causes of likinäköisyydessä are multifaceted, involving both genetic and environmental factors. A family history of myopia significantly increases an individual's risk. Environmental influences, such as prolonged close-up work, like reading or using digital screens, and insufficient time spent outdoors, are also believed to contribute to its development and progression, especially in children.

Symptoms of likinäköisyydessä can include squinting to see distant objects, frequent headaches, eye strain, and difficulty seeing clearly at night or in dim light. It is a very common condition, affecting a substantial portion of the global population, and its prevalence has been increasing in recent decades.

Diagnosis is made through a comprehensive eye examination by an optometrist or ophthalmologist, which involves testing visual acuity and assessing the eye's refractive power. Likinäköisyydessä can be corrected with eyeglasses or contact lenses, which adjust the way light enters the eye to focus it correctly on the retina. In some cases, refractive surgery, such as LASIK, may be an option for adults. Early detection and management are important, especially in children, to prevent potential complications and ensure good vision development.
