Vision Problems After a Concussion? What You Need to Know @DoctorEyeHealth

Uploaded May 2026 | Updated September 2026, 2 weeks ago

Did you know 65–80% of traumatic brain injury (TBI) cases involve some form of visual dysfunction? Last year I got a concussion while snowboarding — and it gave me a front-row seat to exactly how disruptive post-concussion vision problems can be. In this video, I break down the most common vision issues that occur after a concussion, why they happen, how long they can last, and what can actually be done about it.

👁️ What You'll Learn:
Why most post-concussion visual symptoms come from eye movement disorders — not structural eye damage

The 3 most diagnosed eye conditions after concussion: Accommodative Insufficiency, Convergence Insufficiency & Saccadic Dysfunction

Why your eye doctor says "everything looks fine" — but you're still struggling with blurry or double vision

How long post-concussion vision symptoms typically last (and when to seek specialist care)
The role of vision therapy, rehabilitation, and interdisciplinary care in recovery

Vision Problems After a Concussion? What You Need to Know

$Astigmatism Vision Vs Normal #eyes Astigmatism Vision Vs Normal Vision can appear very differently. Astigmatism is a common refractive error caused by an irregularly shaped cornea or lens, which prevents light from focusing properly on the retina. This can lead to blurred or distorted vision at both near and far distances. Astigmatism can be treated effectively with several options depending on its severity. Common treatments include corrective lenses such as glasses or contact lenses, which help adjust the way light enters the eye for clearer vision. For more permanent correction, refractive surgery like LASIK or PRK can reshape the cornea. Your eye care professional can help determine the best treatment option for your individual needs.

$Glasses TOO STRONG? (Over-minused) Heres Whats Happening Are your eyeglasses too strong? This video explores how an overly strong eyeglasses prescription can lead to symptoms like persistent blurred vision and frequent headaches. We also discuss common eye strain symptoms and how they might be related to your current glasses. Understanding these signs is crucial for maintaining good eye health and finding effective headache relief. Learn more about why your glasses might be causing discomfort and what steps you can take to address it, especially if youre experiencing eye strain symptoms or seeking glasses for eye strain. This video also reviews the topic of being over-minused in prescription glasses - which refers to when minus glasses power is prescribed in excess to what is optically required to see well. While this is typically discouraged in clinical practice, we know it still happens. Dr. Allen shares his hot takes on why he thinks we still see people getting overminused in their glasses prescription despite the heavy training to avoid error. Things we cover in this video: - What it means to be over-minused in a glasses prescription - Common symptoms like eye strain, headaches, dizziness, fatigue, and blurry distance or near vision- - Why over-minusing can happen even when eye doctors are well-trained and careful - How modern exams, habits, and visual demand can influence prescriptions - Simple ways to self-assess if your glasses feel “off” - What to tell your eye doctor if you’re worried your prescription is too strong This isn’t about blaming eye doctors—refractions are nuanced, and your visual system changes depending on fatigue, stress, screen use, and more. My goal is to help you better understand your eyes and feel confident advocating for clear, comfortable vision. 👓 If your glasses cause discomfort or just don’t feel right, this video is for you. 📌 Important: This video is for education only and does not replace a comprehensive eye exam. Always discuss symptoms and concerns directly with your eye care provider. If this helped, consider liking the video, subscribing, and sharing it with someone who just got new glasses and isn’t loving them. Being over-minused could be a reason why some people claim that they reversed their need for glasses, meaning they were probably prescribed too strong of glasses at one point and then learned to not over flex their eye muscles to compensate for the extra power.
