Sometimes, there are none—it just shows up. Sometimes, before it appears, you might notice a related growth called a pinguecula.

When you do have symptoms, they can include:

• A raised pink growth on your eye that may keep getting bigger
• Red, irritated, or swollen eyes
• Dry, itchy, or burning eyes
• A feeling that you have sand or grit in your eye
• Eye watering and tearing
• If the pterygium grows onto your cornea, blurred or double vision
