ljusöverkänsligheten

Ljusöverkänslighet, also known as photophobia, is a medical symptom characterized by an abnormal intolerance to light. This means that individuals experiencing photophobia find normal levels of light, both natural and artificial, to be uncomfortable or even painful. The severity of the sensitivity can vary greatly, from mild discomfort to severe pain that can be debilitating.

Photophobia is not a disease in itself, but rather a symptom that can be indicative of an underlying medical condition. Common causes include eye conditions such as migraines, uveitis, keratitis, and conjunctivitis. Neurological conditions like meningitis and encephalitis can also trigger photophobia. Certain medications, as well as head injuries and eye trauma, can contribute to the condition.

The experience of photophobia can manifest in various ways. Besides increased sensitivity, individuals may also report headaches, eye strain, watering eyes, and a general feeling of discomfort when exposed to light. In some cases, the eyes may involuntarily close or squint to mitigate the light exposure.

Diagnosis of photophobia typically involves a thorough medical history and a comprehensive eye examination by an ophthalmologist or optometrist. Identifying the underlying cause is crucial for effective management. Treatment strategies are therefore tailored to the specific condition causing the photophobia. This may involve addressing the primary eye condition, managing neurological disorders, or adjusting medication. While treating the underlying cause is paramount, temporary relief can often be found by avoiding bright lights, wearing sunglasses, and using dim lighting indoors.
