fényhangérzékenységgel

Fényhangérzékenység, also known as photophobia or light sensitivity, is a medical symptom characterized by an abnormal intolerance to light. Individuals experiencing photophobia may find normal light levels uncomfortable or even painful, leading them to squint, close their eyes, or seek dimly lit environments. This condition is not a disease in itself but rather a symptom that can be associated with a wide range of underlying medical issues affecting the eyes or the brain.

Common causes of photophobia include eye conditions such as migraines, corneal abrasions or ulcers, uveitis, conjunctivitis, keratitis, and dry eye syndrome. Neurological conditions like meningitis, encephalitis, and brain tumors can also trigger photophobia due to their impact on the brain's light-processing pathways. Certain medications, including some antibiotics and diuretics, can also induce photosensitivity as a side effect.

The severity of photophobia can vary greatly among individuals, from mild discomfort to severe pain that significantly impacts daily activities. Diagnosis typically involves a thorough medical history, a comprehensive eye examination, and potentially further neurological or imaging tests to identify the underlying cause. Treatment focuses on addressing the root cause of the photophobia. In the meantime, strategies to manage light sensitivity include wearing sunglasses, hats, and reducing exposure to bright lights.
