Depending on what’s causing your watery eyes, there might not be any way to prevent them. If your eyes are irritated by something in the air, or you’re experiencing allergy symptoms, you probably can’t avoid watery eyes.
Make sure to wear all the proper equipment — including eye protection or goggles — for any work or activity that might hurt your eyes.
If you can, avoid your allergy triggers.
Talk to your eye doctor about ways you might be able to prevent watery eyes in the future.
