Red flags & when to go in person for Light Sensitivity (Photophobia) - Triage

Audience: adult

Light sensitivity, or photophobia, is when bright light causes discomfort or pain in your eyes. It can happen for many reasons, including eye infections, migraines, or other health conditions. Sometimes, light sensitivity is mild and can be managed at home or through a telemedicine visit. However, certain signs mean you should see a healthcare provider in person quickly. These include sudden vision changes, severe eye pain, or symptoms that come with fever or headache. Telemedicine can help assess your symptoms, provide advice, and guide you on next steps. But it cannot replace hands-on eye exams or urgent treatments when serious problems are suspected. Understanding when to seek in-person care can protect your vision and overall health.

• Mild to moderate light sensitivity without vision changes or severe pain.
• Symptom assessment and guidance on home care measures.

What telemedicine cannot do

• Severe eye pain or redness indicating possible infection or injury.

What is Light Sensitivity (Photophobia)?

Light sensitivity means your eyes hurt or feel uncomfortable when exposed to bright light. It is not a disease itself but a symptom that can come from many causes, such as eye irritation, infections, migraines, or neurological conditions. People with photophobia may squint, close their eyes, or avoid bright environments.

FAQs

What causes light sensitivity?

Light sensitivity can be caused by eye conditions like infections, dryness, or injuries, as well as by migraines, certain medications, or neurological issues. It is a symptom, not a disease itself.

Can telemedicine diagnose the cause of my light sensitivity?

Telemedicine can help assess your symptoms and guide you on next steps, but it cannot perform a full eye exam needed to diagnose many causes. In-person evaluation may be required for accurate diagnosis.

When should I go to the emergency room for light sensitivity?

Go to the emergency room if you have sudden vision loss, severe eye pain with redness, or light sensitivity accompanied by high fever, headache, neck stiffness, or confusion. These may signal serious conditions needing urgent care.

How can I protect my eyes if I have light sensitivity?

Avoid bright lights and wear sunglasses when outdoors. Use artificial tears if your eyes are dry, and rest your eyes regularly. Follow any specific advice given by your healthcare provider.

Is light sensitivity permanent?

Light sensitivity often improves once the underlying cause is treated. Some chronic conditions may cause ongoing sensitivity, so managing the root cause is important.
