NOTE: IF YOU ARE CURRENTLY EXPERIENCING LOSS OF VISION IN ONE OR BOTH EYES, PLEASE SEEK TREATMENT IMMEDIATELY. THIS IS NOT INTENDED TO ADDRESS URGENT MEDICAL EMERGENCIES.
To echo the above, if you’re reading this article out of one eye, STOP and go see a medical professional immediately. If you’re wondering about common causes of loss of vision in one eye, you’re in the right place.
Loss of vision, especially sudden loss of vision, can be a terrifying thing. Why would vision suddenly go out in just one eye? What if you wake up and you can’t see out of your left eye? What are some common causes?
Here are some common vision problems that can cause a sudden loss of vision in one eye:
1. Optic Neuritis
According to the Mayo Clinic, “Optic neuritis is an inflammation of the optic nerve, the bundle of nerve fibers that transmits visual information from your eye to your brain. Pain and temporary vision loss are common symptoms of optic neuritis.” One episode of Optic Neuritis doesn’t automatically mean a permanent loss of vision, but it will require professional treatment. Optic Neuritis is a serious condition that an optometrist can discover and identify. It’s important to have yearly eye exams to attempt catch these kinds of conditions before they can take effect. While there’s no guarantee that the condition won’t occur suddenly, being consistent with vision care can only help.
2. Central Retinal Artery Occlusion
According to Wikipedia, “Central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked (occluded). There are several different causes of this occlusion, the most common is carotid artery atherosclerosis.” CRAO is another serious condition that has detectable precursors. The body is an ecosystem that works together to function and when one bodily function is failing, it can have an effect on everything else. That is another reason to get frequent eye exams – you can not only learn about the health of your eyes, but your overall health as well.
3. Foreign Object in Eye
If you can’t see out of your left eye, but you do have partial vision (not complete vision loss), it might be a foreign object that has entered your eye. Although not as serious sounding as a disease, a foreign object can be just as dangerous. You’re at risk for corneal abrasions and other damage. If your eye is watering, red, and irritated, it’s a safe guess that something has gotten into your eye that shouldn’t be in there. If that happens to you, treat it seriously and get medical attention promptly. Your vision is important!
Remember: if you ever experience partial or total vision loss, seek attention immediately. Your eyes are important and any vision obstruction should be promptly dealt with. Scheduling a yearly eye exam is a great way to make sure your vision and overall health is monitored. Preventative care is critical to keeping you happy and healthy!
