Sudden blurry vision isn’t normal, so if it ever happens, be sure to call your doctor right away. But before you do that, here is a quick list of all the possible conditions that might be the result of your blurry vision.

One Eye Is Blurry Because of Diabetes?

Diabetes does raise your risk of a specific eye disease called diabetic retinopathy.

Over a long period of time and if you have high blood sugar, tiny blood vessels in your retina, the parts of your eye that see light can be damaged. That damage could lead to swelling in the macula, a part of the retina, undesired and new blood vessels growing and bleeding into the one eye is blurry or both. In addition to blurry vision, diabetic eye disease can also create floating spots in pockets of your vision and sometimes even permanent vision loss.

Getting treated as soon as humanly possible is your best bet for warding off Diabetic eye disease. So be sure to get both eyes checked once a year.

Could A Stroke Be The Reason?

One of the sure fire ways to tell if you’re having a stroke is a sporadic, painless altering of your eyesight; One eye is blurry or complete blurry vision. Call 911 as soon as possible if you’re suddenly having a stroke or experience other stroke warning signs like Loss of Balance, Face drooping, Weakness or numbness in one arm, Dizziness and Slurred speech or other speaking problems.

Could The Reason Be Preeclampsia?

You shouldn’t have a blurry vision if you’re pregnant. And if you do, you take that fact seriously as it could be an early sign of Preeclampsia. It’s a dangerous condition that consists of protein in your urine and incredibly high blood pressure.

Usually, Preeclampsia attacks women who have no experience with high blood pressure and often occurs before and in later pregnancy usually after the 20-week mark. And as you can imagine, Preeclampsia is very dangerous to your unborn child. There might not be any obvious symptoms, but if you have blurry vision or see flashing lights or spots, those are usually signs of it.

Be sure to check with your doctor if any of these signs show up as well: shortness of breath, confusion or a racing heart, vomiting, and nausea starting after the first trimester. Pain in your shoulders, low back or in your belly, weight gain, swelling in your eyes, hands or face and lastly throbbing headaches that never seem to end.

Could The Reason Be A Migraine?

The next level of a headache is a migraine. There are many different symptoms that might come along with the pain, including sensitivity to light and blurry vision. You could experience those signs before a migraine goes into full swing and may continue even after a migraine ends.

More drastic changes to your vision during a migraine are known as an aura and include losing some or all of your vision for a time, seeing light flashes and/or spots or wavy lines.

As I’ve been saying, get in touch with your doctor as soon as possible and get your migraines under control.

Could The Reason Be Psoriasis?

You might have heard of this condition through the following ways: Sore or itchy patches of skin, inflammation, joint pain, scaly, red or thick patches of skin.

There are options for treatments that can get rid of uveitis, but the type you might require will vary depending on your eyes and how they’re affected.

Could The Reason Be Multiple Sclerosis (MS)?

Tiredness, a headache that never ends, Nausea, Seizures, vomiting and personality shifts. If your doctor suspects that you might have a brain tumor, he/she will use different types of tests to see how your brain is operating, check out your spinal cord and throw in some imagining tests to look inside your brain.

Could The Reason Be Parkinson’s Disease?

There are couple signs that occur in this nerve disease before blurry vision. But as the disease starts ramping up, the blurry vision kicks in and can change how your eye movement within your eyelids. As your sight decreases inability, your eyes might start to strain and hurt themselves as they work harder to focus in.
