When someone has a head injury, they typically have vision problems that can be temporary or permanent. When a vision problem is causing or contributing to a problem with reading, balance, or movement, the recovery process will move slowly until the vision component is treated. Sometimes symptoms of a concussion might not even appear for days, even weeks, after the accident. Additionally, some symptoms might disappear after a time, such as eye pain or headaches, and yet other symptoms remain, such as blurred or double vision. If you suspect that a concussion has caused vision problems resulting in difficulty coping with daily activities, see a Developmental Optometrist for a visual evaluation.
