Light and Noise Sensitivity After a Concussion

After a concussion, ordinary light and sound can feel overwhelming.

Common experiences

Squinting under store lights, headaches at screens, and avoiding noisy places.

Coping tips to discuss

Screen breaks, brightness settings, and quieter environments. Ask your provider before using tinted lenses.

Documenting it

Report it at each visit. It is a commonly recognized concussion symptom.

When it's an emergency

Go to the ER right away for a worsening headache, repeated vomiting, a seizure, weakness, slurred speech, or increasing confusion. Mobile testing is not emergency care.

Everyday life gets louder and brighter

After a concussion, many people find ordinary environments overwhelming. Office fluorescent lights, phone and computer screens, sunlight on the water, a restaurant at dinnertime, a classroom, or a child's birthday party can trigger headaches, fatigue, or irritability. Some start wearing sunglasses indoors or avoiding social events. These sensitivities are common after head injuries and are worth discussing with a provider. They're not a sign of being "dramatic."

Why it happens

A concussion can affect how the brain filters and processes sensory input, so normal levels of light or sound feel more intense. Fatigue, headache, and poor sleep can make this sensitivity worse. For many people it eases over time, but when it lingers it can significantly limit work and daily life.

Adjustments that may help while you recover

Practical steps include lowering screen brightness, enabling dark mode, taking regular screen breaks, using softer lighting at home, wearing a hat or sunglasses outdoors, and choosing quieter times for errands. At work, a desk away from bright windows or busy walkways may help. Talk with your provider about how much to avoid triggers versus gradually reintroducing them, because the right balance varies from person to person.

Telling your provider the details

Be specific: which lights or sounds bother you, how quickly symptoms start, how long they last, and what you've changed in your routine because of them. These details help your treating provider understand how much the sensitivity affects your function.

When to ask about testing

Persistent light or noise sensitivity, especially when combined with headaches, dizziness, or trouble concentrating, is a reasonable reason to ask your provider about standardized testing. Eye-movement, neurocognitive, and brain-activity results, reviewed by a physician, can guide next steps such as referral to a vision or vestibular specialist.

Emergency warning signs

Sudden vision loss, double vision, severe or worsening headache, repeated vomiting, confusion, seizures, or weakness need emergency care. Call 911.

At work and school

Ask whether you can temporarily adjust your environment: dimmer lighting, noise-reducing headphones, a quieter workspace, printed materials instead of screens, or scheduled breaks. Your provider can document recommended accommodations. Many employers and schools are willing to make short-term adjustments when they understand that the request is medical and temporary. Keep track of which changes help most so you can report back.
