valgustundlikkuse

Valgustundlikkus, meaning light sensitivity in Estonian, refers to an increased sensitivity to light. This condition can manifest in various ways, from mild discomfort to severe pain in the eyes when exposed to light. It is a symptom that can be associated with a range of underlying causes, rather than a disease in itself.

Common causes of valgustundlikkus include eye conditions such as iritis (inflammation of the iris), uveitis (inflammation of the middle layer of the eye), keratitis (inflammation of the cornea), or certain types of eye infections. Migraines are also frequently accompanied by photophobia, where light exacerbates the headache. Neurological conditions like meningitis or encephalitis can also present with light sensitivity as a symptom due to irritation of the brain and its protective membranes.

Exposure to certain medications or substances can also lead to temporary or persistent valgustundlikkus. Additionally, it can be a sign of eye strain from prolonged screen time or a result of recent eye surgery or injury. The severity of light sensitivity can vary significantly from person to person, and it can affect one or both eyes. If experiencing significant valgustundlikkus, it is advisable to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.
