3. Eye and Head Pain
If you’re noticing some sudden sharp pangs of pain in your eyes, or you have a bad headache that seems to have come out of nowhere, you should keep a close eye on it (so to speak). These may be symptoms of acute angle-closure glaucoma, another common form of the disease.
AllAboutVision.com notes these sudden symptoms (which also can include nausea and vomiting) can warrant a trip to the emergency room, and the “attacks” can last a few hours. Each time you have one of these pain episodes, it can further erode your vision, adds the source.
