Yes. A car accident can cause real vision problems, including blurred or double vision, light sensitivity, and permanent vision loss in severe cases. The cause is usually a brain injury, a whiplash neck injury, or direct trauma to the eye from an airbag or broken glass. See an eye doctor soon after any crash.
A vision problem after a car accident can come from several different injuries, and figuring out which one is behind your symptoms matters for both your treatment and your claim. Head injuries, a whiplash neck injury, and direct trauma to the eye can each affect your sight in different ways. Below are the warning signs worth an urgent exam, plus how Oklahoma law treats a vision injury caused by someone else’s crash.
What Vision Problems Can a Car Accident Cause?
A car accident can cause vision problems through three different paths: a traumatic brain injury, a whiplash neck injury, or a direct blow to the eye itself. Whichever one is behind it, the resulting symptoms often look similar, including:
- Blurred or blurry vision
- Double vision (diplopia)
- Sensitivity to light
- Loss of peripheral, or side, vision (a narrowed visual field)
- Eye pain
- In severe cases, permanent vision loss
The same crash can cause more than one hidden injury at once. Some people also develop a spinal condition the same crash may have caused or a joint condition the same trauma can trigger, alongside changes in vision. A full exam, not just an eye exam, helps make sure nothing gets missed.
How a Traumatic Brain Injury Affects Your Vision
Car accidents are one of the leading causes of traumatic brain injury (TBI) in the United States, ranking behind falls and object strikes, per the CDC’s surveillance data on traumatic brain injury. Even a TBI doctors classify as mild, often called a concussion, can damage the cranial nerves that control eye function: the optic nerve, oculomotor nerve, trochlear nerve, and abducens nerve. That damage can produce:
- Binocular vision dysfunction (BVD) or strabismus, where the eyes stop aligning properly
- Decreased visual acuity, meaning your vision becomes less sharp
- Double vision (diplopia) or blurry vision
- Exotropia, a type of strabismus where one or both eyes drift outward
- A narrowed visual field, sometimes described as tunnel vision
The occipital lobe, the part of the brain that processes what your eyes see, sits at the back of the skull, an area Cleveland Clinic’s overview of the occipital lobe describes as especially vulnerable to the kind of impact a car accident delivers. A TBI severe enough to affect vision is usually severe enough to justify a brain injury claim built around vision loss, not just a standalone eye injury claim.
Direct Eye Trauma: Corneal Abrasions, Retinal Detachment, and Other Injuries
Not every vision problem after a crash starts in the brain or the neck. The eye itself can take a direct hit, from shattered glass, a dashboard or steering wheel, a deploying airbag, or the seatbelt catching the face during a violent stop.
A corneal abrasion, a scratch on the clear surface of the eye, is one of the most common results. It causes sharp pain, redness, light sensitivity, and heavy tearing, and it usually heals within a few days once a doctor confirms there is no deeper damage or infection. Retinal detachment is the more serious risk: it happens when the retina pulls away from the back of the eye, and it can follow blunt trauma even when the eye looks fine from the outside. Sudden flashes of light, a sudden increase in floaters, or a shadow or curtain moving across part of your vision are emergency signs that need same-day care, since a detached retina left alone can cause permanent vision loss. In the most severe direct-impact cases, a car accident can also cause a globe rupture or bleeding inside the eye (hyphema), both of which need immediate treatment.
Whiplash Can Cause Blurred Vision and Ringing Ears, Too
A whiplash neck injury can disturb your vision and hearing even without any blow to the head. Whiplash happens when a crash, usually a rear-end collision, pushes the neck’s muscles and ligaments beyond their normal range of motion faster than they can absorb it. It does not take a high-speed crash to cause it: whiplash has been documented in collisions as slow as roughly 15 miles per hour. A cervical sprain or strain from whiplash can lead to:
- Diplopia, meaning double vision, along with blurred vision or trouble following objects with your eyes
- Tinnitus, a high-pitched ringing (or buzzing or hissing) in the ears that can occur even in a silent room
Whiplash can also cause dizziness, neck and shoulder pain, and nerve symptoms like numbness or tingling that have nothing to do with vision. For the fuller set of symptoms and recovery timeline, see the risks of leaving whiplash untreated.
Certain Times of Day Raise Both Vision and Accident Risks
There is a second link between vision and car accidents, running the opposite direction: driver vision problems can help cause a crash, not just result from one. Low light at dawn and dusk, sun glare, and driver eye fatigue all reduce visibility, and crashes cluster during the dusk-and-dawn hours when crashes spike. If poor visibility played a role in how your accident happened, that is a fact worth documenting for your claim, separate from any vision injury the crash itself caused.
Vision Problems After a Car Accident: FAQs
How long after a car accident can vision problems appear?
Vision problems can show up immediately or take days to develop, especially with a mild TBI or whiplash, where swelling and inflammation build gradually. Watch your vision closely for at least a few weeks after any crash involving a head, neck, or facial impact, and get checked again if anything changes.
Can a car accident cause permanent vision loss?
Yes, in severe cases.
Vision loss after a traumatic brain injury is well documented. The VA’s optometry research on vision changes after TBI describes lasting visual impairment in veterans who suffered head trauma, and the same nerve and brain damage can happen in a car accident. Prompt treatment lowers the risk, but it cannot always prevent it.
Should I see an eye doctor after a car accident, even if my vision seems fine?
Yes. Some head injuries and corneal abrasions do not always cause symptoms right away. An eye doctor can check for damage a general emergency room exam might miss, and having that record close to the accident date also helps connect any later symptoms to the crash.
Can I get compensation for vision problems caused by someone else’s crash?
Yes, if another driver caused the accident. A vision injury claim can include your medical bills, lost income while you recover, and pain and suffering, and it is typically paid through the at-fault driver’s insurance. Oklahoma gives you two years from the date of the crash to file a lawsuit under 12 O.S. Section 95 if the insurance company will not pay fairly.
