You may be used to experiencing blurred vision, loss of sharpness in what you’re seeing, when not wearing your glasses if you’re near or farsighted. But blurred vision can be a symptom of the following conditions that caused you to have to wear glasses or a more serious health problem. If you've been diagnosed with or suspect you may have one of these diseases, you'll want to see your doctor when blurry vision occurs.
Diabetes can cause "high levels of blood sugar to pull fluid from your tissues, including the lenses of your eyes," according the Mayo Clinic. "This affects your ability to focus."
If the lack of focus, known as blurry vision, isn't treated "diabetes can cause new blood vessels to form in your retina — the back part of your eye — and damage established vessels," the Mayo Clinic says. "For most people, these early changes do not cause vision problems. However, if these changes progress undetected, they can lead to vision loss and blindness."
"A variety of eye disorders are caused by or associated with neurologic diseases, such as multiple sclerosis, strokes and brain tumors," says The John Hopkins University. Blurred vision associated with these diseases may require the care of a variety of doctors who interact with each other to treat the disease and eye symptoms.
Optic neuritis is a vision disease that is "believed to develop when the immune system mistakenly targets the substance covering your optic nerve" and both damages and inflames the nerve, according to the Mayo Clinic. "In people with optic neuritis, the risk of developing multiple sclerosis following one episode of optic neuritis is about 50 percent over a lifetime."
As with any disease or symptom, you don't want to let blurred vision progress without diagnosis because early detection and/or treatment can lead to improved long term results for patients. If you're experiencing blurred vision, seek medical help immediately.
