Glaucoma is a serious eye condition that can lead to vision loss if left untreated. Recognizing the symptoms of glaucoma early on is crucial for preserving your eyesight. Here are some common symptoms to watch out for:

1. Gradual Loss of Peripheral Vision: One of the hallmarks of glaucoma is the gradual loss of peripheral vision. You may notice that you are having difficulty seeing objects or people to the side of your field of vision.

2. Blurred Vision: Blurred vision, especially at the edges, is another common symptom of glaucoma. This can make it challenging to focus on objects or read text clearly.

3. Seeing Halos Around Lights: Some people with glaucoma report seeing halos or rainbow-colored rings around lights, especially at night. This can be a sign of increased pressure within the eye.

4. Eye Pain or Headaches: Glaucoma can cause eye pain, headaches, or discomfort, particularly as the condition progresses. If you experience persistent eye pain or headaches, it's essential to get your eyes checked by a healthcare professional.

5. Nausea or Vomiting: In severe cases of acute angle-closure glaucoma, symptoms may include nausea, vomiting, and sudden eye pain. If you experience these symptoms along with vision changes, seek immediate medical attention.

6. Increased Intraocular Pressure: Glaucoma often leads to increased pressure within the eye, which can manifest as redness, teary eyes, or a feeling of pressure behind the eyes.

If you notice any of these symptoms, it's crucial to see an eye doctor for a comprehensive eye exam. Early detection and treatment of glaucoma can help prevent further vision loss and preserve your eyesight. Remember, regular eye exams are essential for maintaining good eye health and catching conditions like glaucoma in their early stages.
