4. Blind Spots
If you have ever experienced a small blind spot in your vision, it can be quite scary. But this situation can also indicate that you are experiencing a migraine aura, especially is you also see shimmering lights or a wavy line.
This blind spot and lights may be followed by a painful headache (6). If this happens a lot, you can speak to your doctor about ways to deal with the symptoms and even look to possible triggers so you can avoid them.
5. Bulging Eyes
We have all had times when you think your eyes are playing tricks on you.
You rub your eyes or blink several times and things seem to clear. But if you feel a consistent bulging sensation in your eyes, it may again be related to your thyroid.
In fact, one of the most common causes of protruding eyes is associated with hyperthyroidism, a condition in which your thyroid is too active. Also knowns as Grave’s Disease, this autoimmune disorder causes your thyroid gland to create too much thyroid hormone.
One symptom, called Graves’ ophthalmopathy, occurs when your eyes appear enlarged when your eyelids retract, causing your eyes to bulge from your eye sockets (7).
According to the National Institute of Diabetes and Digestive and Kidney Diseases, up to 30 percent of people that develop Graves’ disease will get a mild case of Graves’ ophthalmopathy. And up to 5 percent will experience a severe case (8).
So if your eyes feel like they are bugging out, speak to your doctor.
