People suffering from a concussion can develop a sensitivity to light during regular recovery or when experiencing persisting symptoms.
Symptoms of light sensitivity include:
- Eye strain and discomfort
-
Headaches
-
Nausea
- Dizziness
- Trouble sleeping
- Anxiety
-
Computer screen intolerance (CSI)
LCD screens, or sun, fluorescent, flashing, or bright lights can trigger symptoms. Experiencing any of these symptoms can make it hard to perform basic everyday tasks, such as going to the store, spending time with family and friends, going to work, using or watching an electronic device, or spending time outdoors.
You can reduce symptoms related to vision and CSI by making accommodations or changes to your home, school, or workplace environments. This may include:
- Avoiding or reducing screen time
-
Making adjustments to your computer screen brightness and colour settings
-
Wearing sunglasses or blue light filtering glasses
-
Avoiding or reducing bright lights and fluorescent lights
-
Visiting an optometrist to adjust your vision prescription
-
Making an appointment with an ophthalmologist to rule out pressure in the eyes
Dr. Charles Tator, a neurosurgeon and leading Canadian expert on concussion, recently presented a webinar about light sensitivity and the latest research on CSI. View the recording of the webinar and slide deck on the University Health Network website.
