Vision Problems After a Concussion: A Checklist for Teens and Adults

Vision problems are a recognized concussion symptom. The CDC lists "vision problems" and "bothered by light or noise" among concussion symptoms, and the National Eye Institute notes that convergence insufficiency is common after a brain injury or concussion.

Symptoms to note in the weeks after

If any of these continue after a concussion, mention them to your doctor and ask whether a vision evaluation makes sense:

• Blurry vision, or vision that changes during the day
• Double vision, especially when tired
• Eye strain or headaches after reading or screens
• Trouble reading: losing place, slower reading, words moving
• Sensitivity to light
• Dizziness or discomfort in busy visual environments (stores, crowds)
• Misjudging distances or feeling unsteady

This list is for organizing your observations. It is not a scored test. Some vision therapy practices, including VDCNJ, use a published questionnaire called the Brain Injury Vision Symptom Survey (BIVSS; Laukkanen, Scheiman & Hayes, Optometry and Vision Science, 2017); you can take VDCNJ's version on our Brain Injury Vision Symptom Survey page (VDCNJ is the owner's practice; see disclosure).

Next steps

Talk with the doctor managing your concussion care. A neuro-optometric or functional vision evaluation can check eye teaming, focusing, and eye movements. Treatment, when needed, addresses the vision problem as one part of overall recovery.
