Symptoms that show up weeks later
Patients often feel reasonably normal at rest and then struggle the moment visual demand rises: a page of text, a spreadsheet, a grocery aisle, oncoming headlights. Common reports are words moving or doubling, screens becoming intolerable, headaches building through the day, and dizziness triggered by eye movement.
The vision–concussion link
A large share of the brain's circuitry is involved in visual processing, so a concussion frequently disrupts eye tracking, focusing, and eye teaming even when acuity is completely normal. The eyes are healthy; the coordination between them is what changed.
What we test and how it's documented
We measure tracking, eye jumps, fixation stability, convergence at near, and how quickly focus resets between near and far. Every measurement is scored against published clinical norms and issued as a formal written report, reviewed and signed by Dr. Rizwan Jaffer, O.D., Texas License #7014TG. No dilation and no drops are required. Same-week appointments are available across six Houston-area locations, including Sugar Land at 345 Hwy 6, and we see patients from throughout Texas.
Sports, work, and accident concussions
We see athletes cleared to return to play who still cannot get through a textbook, workers whose head impact happened on the job, and drivers and passengers hurt in a collision — see vision problems after a car accident and who to see after a crash. When a claim or case is involved, the same report supports Letter of Protection referrals and expert witness work.
Frequently Asked Questions
How long do vision problems last after a concussion?
There is no single timeline. Some people clear within weeks; others carry symptoms much longer. What often separates the two is whether the underlying eye-teaming or tracking problem was identified and addressed rather than waited out.
Why can't I read after a concussion?
Reading requires dozens of precise eye jumps per line, with both eyes landing on the same word at the same moment. That coordination is commonly disrupted after a head injury, which is why patients lose their place, re-read lines, and tire quickly even with clear eyesight.
What is post-trauma vision syndrome?
It is the term used for the cluster of visual symptoms that can follow a head injury — unstable fixation, convergence difficulty, light sensitivity, and a sense that words or the environment are moving — when the eyes themselves appear healthy.
Do I need a referral?
