How a Concussion Can Affect Eyesight

While many people think a concussion is only a minor injury, it is classified as a traumatic brain injury and should be taken seriously. Often occurring in contact sports or when people suffer auto accidents or falls, a concussion involves the brain actually moving around inside your skull. While this will likely result in you having a headache and possibly some nausea, few people realize a concussion can also affect their eyesight. As for how, here are some common ways.

Post-Trauma Vision Syndrome

If you have persistent visual problems following a concussion, doctors may diagnose you with post-trauma vision syndrome. Happening in people who suffer even mild concussions, PTVS involves various issues that may alter your eyesight temporarily. However, when a concussion is very severe, people can experience total blindness for a period of time.

Double Vision

Most common with severe concussions, double vision is often a sign that a brain injury may be worse than originally thought, and thus should always be taken very seriously. An extremely disorienting condition, double vision results in dizziness, reduced hand-eye coordination, and difficulty walking, reading, and balancing.

Accommodative Dysfunction

Referring to a person having difficulty switching their focus from nearby objects to those located at a distance, accommodative dysfunction is something you may experience following any type of concussion. Hard to diagnose because your eyes will otherwise appear healthy, it will often dissipate on its own over time. Caused by an injury to the part of the brain stem that controls focusing, it rarely shows itself on an MRI.

Convergence Insufficiency

If you are diagnosed with this, it means your eyes will have difficulty establishing and maintaining binocular vision that is most often used when reading or working at a computer. In essence, your eyes do not want to work together and are often tired and achy when trying to do these tasks.

Sensitivity to Light

Finally, your eyes may be very sensitive to light after a concussion. When the brain suffers a blow, it becomes much harder for it to adjust to different levels of brightness, though researchers are now quite sure why.

Should you suffer these or other problems with your eyesight following a blow to the head, always seek medical treatment as soon as possible.


Bifocal Contact Lenses: An Introduction with FAQs

Bifocal contact lenses allow people who normally must rely on bifocal eyeglasses to get rid of their glasses and still see just as well in their day-to-day lives. If you wear bifocal eyeglasses, it is a good idea to talk to your eye doctor about bifocal lenses. Here is a look at some of the general questions you may have and the answers you will want to know.

Who is a good candidate for bifocal contact lenses?

Bifocal lenses tend to be a good option for patients who have been diagnosed with presbyopia, which is a condition that affects your ability to see objects up-close. If you already have bifocal lenses, you may have presbyopia or another condition that affects your vision capabilities when it comes to looking at objects in close proximity. People tend to be the best candidates for bifocal contact lenses as well if:

  • They do not have other eye health conditions like dry eye syndrome
  • They are comfortable with wearing contact lenses; not every patient is comfortable
  • They are vigilant about eye health, do not smoke, and can follow guidelines for changing lenses

How do bifocal contact lenses work?

Bifocal contact lenses work in much the same way as bifocal eyeglasses, they have separated sections that offer different optical adjustments. Therefore, you will see things differently depending on what direction you are focusing your eyes. For example, if you are looking downward, as you would while reading, you will see things in a certain way, but if you are looking straight ahead, you will see things a certain way.

Are bifocal contact lenses expensive?

Bifocal contact lenses can be a bit more expensive than traditional lenses simply because they are made differently with specific features. Nevertheless, the lenses are considered affordable and may be covered by certain types of medical insurance.
