Can a Car Accident Cause Eye Pain or Vision Changes?

Separate an eye injury from a visual symptom

Eye pain can follow direct contact with an airbag, glass, debris, or another object. Vision can also change without obvious injury to the outside of the eye, including after a jolt to the head or body. Describe exactly what is different: blurred vision, double vision, missing areas, flashes, floaters, light sensitivity, trouble focusing, pain with eye movement, redness, or a curtain-like shadow.

Note whether one eye or both are affected. Do not press or rub an injured eye. MedlinePlus's eye-emergency guidance explains that blunt trauma and other eye injuries can threaten vision and need prompt attention.

Some vision changes are emergencies

Seek emergency care for partial or complete loss of vision, even when temporary. Double vision, sudden distorted vision, or sudden blurred vision with eye pain also requires urgent assessment. An embedded object, visible cut, uncontrolled bleeding, severe eye pain, or a painful red eye after the crash should not wait for a routine appointment.

Do not try to remove an embedded object yourself. MedlinePlus's vision-problem guidance lists sudden blindness, double vision, sudden distorted areas, and a red painful eye with blurred vision among symptoms needing emergency care.

Check for concussion danger signs

Vision problems and sensitivity to light can occur with a mild traumatic brain injury or concussion. A concussion can result from a jolt to the body, so a person does not need to remember a direct head strike for the possibility to be considered. Call 911 or go to an emergency department for one pupil larger than the other, double vision with other head-injury warning signs, a worsening headache, repeated vomiting, seizure, slurred speech, weakness, numbness, increasing confusion, unusual behavior, or inability to wake.

The CDC concussion symptom guide distinguishes common symptoms from danger signs. MedlinePlus also summarizes concussion evaluation and symptoms.

Bring a precise visual timeline

Record the first visual change, how long it lasted, and whether it is constant or comes and goes. Include headache, dizziness, nausea, balance problems, memory gaps, facial pain, or any direct contact near the eye. Tell the clinician about contact lenses, glasses, prior eye disease, migraines, earlier concussion, medication, and blood-thinning drugs. Bring emergency records and any photo showing bruising or swelling, but do not delay care to collect documentation.

A medical or eye professional may assess vision, pupils, eye movement, the eye surface and internal structures, neurological findings, or other features according to the symptoms. Ask which finding determines the next step.

• One eye or both eyes
• Blurred, double, missing, flashing, or distorted vision
• Direct eye or facial contact
• Headache, vomiting, dizziness, weakness, or confusion
• The exact onset and direction of change

Protect safety during follow-up

Do not drive while vision, balance, concentration, reaction time, or alertness is impaired. Arrange transportation and follow written limits for screens, work, physical activity, and driving. MedlinePlus's traumatic brain injury overview emphasizes prompt medical care when trauma may have affected the brain.

Eye care and head-injury follow-up may need to proceed together rather than treating one symptom in isolation. Report new vision loss, increasing pain, a new pupil difference, worsening headache, repeated vomiting, weakness, confusion, or another decline immediately. Later musculoskeletal care should not replace eye or neurological evaluation.
