What to do if i have mild allergies and i'm only 17. is there a risk for glaucoma?

Not directly: Allergies do not directly cause glaucoma. Some prescription and over the counter allergy medications however carry a warning for those already diagnosed with glaucoma. If you do not have glaucoma, you should feel free to use those medications, especially at age 17.

Doubtful: Discuss with your parents what you may take over the counter for your seasonal or perennial allergies (based on your health). Unless you have been diagnosed with eye problems at a young age, it would be very unlikely that you would have any risk taking anti-allergy medications 4 your eyes. Most of the effective medications contain an antihistamine, which may dry your eyes & possibly blur vision.
