Blurred vision is one of the most common eye conditions. A problem with any of the components of your eye, such as the cornea, retina, or optic nerve, can cause sudden blurred vision. Slowly progressive blurred vision is usually caused by long-term medical conditions. However, sudden blurry vision in one eye is most often caused by a single event.
So, in the following section, we will show you what causes blurred vision.
What Causes Blurred Vision?
In this section, we will show you the causes of blurred vision and the causes of sudden blurry vision in one eye. If you do not know, keep on your reading.
- Blurred vision may occur when your retina tears away from the back of your eye and loses its blood and nerve supply. When it happens, you can see flashing lights and black flecks followed by an area of blurred or absent vision.
- Blurry or lost vision in both eyes can occur when you have a stroke affecting the part of your brain that controls vision.
- Blurred vision can be caused by wet macular degeneration. The center of your retina is called the macula. Abnormal vessels may grow, causing blood and other fluid to leak into the macula. This is called wet macular degeneration. Unlike dry macular degeneration, this type can begin suddenly and progress rapidly.
- Blurred vision can also be caused by eye strain, which can occur after looking at and focusing on something for a long time without a break. When it’s the result of focusing on an electronic device like a computer or cellphone, it is sometimes called digital eye strain. Other causes include reading and driving, especially at night and in poor weather.
- Conjunctivitis can often lead to blurred vision. Conjunctivitis is an infection of the outside lining of your eye and is usually caused by a virus but can also be caused by bacteria or allergies.
- Sudden blurry vision in one eye can be caused by a corneal abrasion. Your cornea is the clear covering on the front of your eye. When it gets scratched or injured, you may develop a corneal abrasion. So, besides blurry vision, you may feel like there is something in your eyes.
As for what causes blurred vision, there are some other reasons for blurred vision. If you feel discomfort in your eyes, you need to see an eye doctor at once.
How to Treat Blurred Vision?
As for how to treat blurred vision, in fact, different causes need different treatments. So, we will list some of them.
If the blurred vision is caused by the stroke, prompt and appropriate treatment is critical to prevent the death of your brain cells. If it is caused by wet macular degeneration, medications injected into the eye may help improve vision. Treatment with laser photocoagulation can slow vision loss but can’t restore your vision. Special vision-enhancing devices are sometimes used to help you see better.
All in all, when you feel sudden blurry vision in one eye, see the doctor immediately and he will give you some treatment.
