Light sensitivity
Overview
Light sensitivity, also known as photophobia, is a condition where the eyes become unusually sensitive to bright lights, causing discomfort, pain, or the need to squint or close the eyes. This symptom can range from mild discomfort in bright environments to severe pain when exposed to normal lighting conditions.
Common Causes
Light sensitivity can occur due to several common reasons. Eye strain from prolonged screen time or reading in poor lighting often makes eyes more sensitive to bright lights. Certain medications, including some antibiotics and pain relievers, can increase light sensitivity as a side effect. Dehydration and lack of sleep frequently contribute to this discomfort. Spending too much time indoors and then suddenly being exposed to bright sunlight can also trigger sensitivity.
Severity Levels
Mild: You may feel slightly uncomfortable in bright sunlight or well-lit rooms and find yourself squinting more than usual. Indoor lighting generally doesn't bother you, but you might prefer dimmer settings.
Moderate: Bright lights cause noticeable discomfort and you actively avoid sunny areas or bright indoor spaces. You may need to wear sunglasses indoors occasionally and prefer keeping lights low at home.
Severe: Even normal indoor lighting causes significant pain or discomfort, forcing you to stay in darkened rooms. You rely heavily on sunglasses and may have difficulty performing daily activities due to lighting sensitivity.
Medical Attention
Seek immediate medical attention if light sensitivity occurs suddenly with severe headache, neck stiffness, fever, or vision changes, as these may indicate serious conditions like meningitis or eye infections. Contact your doctor if the sensitivity persists for more than a few days, interferes with daily activities, or is accompanied by eye pain, redness, or discharge. Also consult a healthcare provider if you experience light sensitivity after an eye injury or if it develops alongside other concerning symptoms like nausea or confusion.
