Concussions in Sports: Protecting Your Vision and Brain Health
What Is a Concussion?
A concussion is a type of mild traumatic brain injury that happens when your brain is shaken inside your skull from a hit, bump, or jolt to the head or body. This injury temporarily changes how your brain works and can cause many different symptoms, including problems with your vision.
Concussions occur most often in contact sports like football, soccer, and hockey when players collide, fall hard, or get hit by equipment. However, even non-contact sports like gymnastics, cycling, or baseball can cause concussions from unexpected falls or being struck by a ball.
Concussion symptoms can appear right away or develop over hours or days. Common signs include headaches, dizziness, feeling confused or foggy, trouble remembering things, and nausea. Many people also experience vision problems that can be warning signs of a brain injury.
Your brain controls how your eyes move, work together, and process visual information. When your brain is injured in a concussion, these important functions can be disrupted, leading to blurry vision, double vision, trouble focusing, or problems with balance and coordination.
Your eyes work closely with your inner ear and brain to help you maintain balance and understand where you are in space. After a concussion, this connection can be damaged, making you feel dizzy, unsteady, or like the room is spinning, which directly affects your coordination and safety.
While athletes in contact sports are at a higher risk, anyone can sustain a concussion. Participants in recreational activities, gymnasts, and cheerleaders are also at risk. It is important for all active individuals to be aware of the signs and dangers of concussions.
Vision Problems After a Concussion
Up to 90% of people who have concussions experience some type of vision problem. Recognizing these issues is the first step toward seeking the right care and ensuring a smooth recovery.
Seeing blurry or double images is one of the most common vision problems after a concussion. This happens when your brain has trouble controlling the eye muscles or cannot properly combine the images from both eyes into one clear picture.
After a concussion, your eyes may have to work much harder to focus. This extra effort causes eye strain, making your eyes feel tired or heavy. The strain often leads to headaches, especially after reading or using digital screens.
Many people become very sensitive to bright lights or glare after a concussion. Normal lighting that never bothered you before may now cause discomfort or headaches, making it hard to be in brightly lit classrooms, offices, or outdoors.
After a concussion, tracking moving objects like a ball during sports or following lines of text while reading can become very difficult. Your eyes may not move smoothly or may lose their place frequently, making activities that were once easy feel frustrating.
Changing focus between objects at different distances, like looking from a whiteboard to your notes in class, may become slow or difficult. This problem can make school and work much more challenging and tiring than before the injury.
Judging distances and the depth of objects may become harder after a concussion. This can make activities like driving, going up and down stairs, or catching a ball more dangerous and difficult.
How Eye Care Professionals Help After a Concussion
Eye doctors who specialize in concussion-related vision problems can provide important testing, diagnosis, and treatment to help your vision recover and improve your quality of life.
A thorough eye exam after a concussion includes special tests that check how well your eyes move together, focus at different distances, and process visual information. These tests can identify specific problems that regular eye exams might miss and help create a treatment plan.
Vision therapy involves a personalized program of exercises and activities designed to retrain your brain and eyes to work together properly again.
- These programs are customized to address your specific problems with eye tracking, focusing, and coordination.
- Therapy may include computer-based exercises, balance training, and eye movement drills to rebuild visual skills.
Prescription glasses with special lenses, prisms, or tints can help reduce symptoms like double vision, eye strain, and light sensitivity. These glasses are specially designed based on your unique vision problems and can provide significant relief while your eyes heal.
Special tinted glasses, such as those with an FL-41 tint, can help manage light sensitivity. These lenses are particularly helpful for reducing discomfort from fluorescent lights and computer screens, allowing you to function more comfortably indoors and out.
Eye care professionals often work together with your family doctor, neurologist, physical therapist, and other specialists to ensure you receive complete and integrated care for all aspects of your concussion recovery.
Preventing Concussions and Protecting Your Eyes in Sports
While it is impossible to prevent all concussions, following safety guidelines and using proper equipment can significantly reduce your risk of brain and eye injuries during sports.
Always wear helmets, mouthguards, and other protective gear that fits correctly and meets safety standards for your sport. Make sure equipment is in good condition and replace damaged items immediately.
Proper training in safe tackling, heading, and other sport-specific techniques can help reduce the risk of head impacts. Coaches should emphasize good sportsmanship and fair play to minimize dangerous collisions.
Protective eyewear made with impact-resistant polycarbonate lenses should be worn in sports with a high risk of eye injury. Sports goggles not only protect your eyes from direct trauma but may also provide some protection against concussions.
Never return to sports while still experiencing concussion symptoms, as this greatly increases your risk of a more serious brain injury. Follow medical advice carefully and complete all required steps before returning to play.
Pre-season testing helps establish an athlete’s normal brain and vision function. This baseline makes it easier for healthcare professionals to identify changes and measure recovery after an injury.
Recovery and Long-Term Effects of Concussions
Recovery from a concussion takes time, and vision problems may be among the last symptoms to improve. Understanding the healing process helps set realistic expectations and ensures proper care.
Your brain needs both physical and mental rest to heal. Avoid activities that make your symptoms worse, including screen time and intense physical activity, until cleared by your doctor. Recovery should happen in stages, with a slow return to normal routines.
This condition involves a combination of vision problems that persist long after the initial injury, including difficulties with eye tracking, focusing, and visual processing. Specialized vision therapy can help manage these ongoing challenges.
Persistent vision problems can affect your ability to work, attend school, drive safely, or participate in sports. Early identification and treatment of vision problems can help prevent or minimize these long-term impacts on your quality of life.
When to Seek Emergency Care for a Concussion
While most concussions are mild and heal with proper care, some warning signs indicate a medical emergency that requires immediate attention to prevent serious complications.
Any loss of consciousness, even for a few seconds, after a head injury requires immediate emergency medical evaluation. This includes feeling like you blacked out or cannot remember what happened right after the injury.
Seek emergency care if you have a severe headache that gets worse, repeated vomiting, seizures, extreme confusion, or slurred speech. These symptoms may indicate a more serious brain injury that needs urgent treatment.
Sudden vision loss, severe double vision that does not improve, or pupils that are different sizes are serious warning signs. These symptoms require immediate emergency medical attention.
Unusual behavior, extreme confusion, difficulty staying awake, or the inability to wake someone up after a head injury all indicate a medical emergency. Call for emergency help immediately in these situations.
FAQs About Concussions and Eye Health
Patients often have questions about how concussions impact vision and what steps to take for recovery. These answers provide detailed insights to help you understand potential issues and seek appropriate care.
