I've noticed my eyesight getting worse lately. What are the signs of a serious eye condition?

The most common sign of a serious eye condition is blurred vision, which can be caused by several different things. It could be an infection or inflammation in your eyes, or it could be due to a more serious underlying problem such as glaucoma or macular degeneration. If you experience any changes in your vision that persist for more than two weeks, it's important to consult a doctor.
