Can wearing glasses or sunglasses outdoors help reduce eye irritation from crested wheatgrass pollen?

Glasses or sunglasses can indeed serve as a physical barrier that helps prevent crested wheatgrass pollen from reaching the eyes, thus minimizing associated irritation such as itchiness, redness, and watering. This type of pollen is a common allergen and when it enters the eyes, it can trigger an allergic reaction. So, wearing sunglasses or glasses when outdoors, especially during the pollen season, may help to significantly alleviate these allergy symptoms.

However, it's essential to remember that glasses and sunglasses only offer partial protection. They don't completely seal off the eyes and tiny pollen particles can still get around them. To better manage eye irritation from pollen allergies, consider also using antihistamine eye drops, which can help to further alleviate symptoms by blocking the body’s histamine release - the compound that triggers allergy symptoms.

Additionally, a daily non-drowsy over-the-counter or prescription antihistamine pill may also help to internally combat the allergic reaction to pollen. These medicines can ease sneezing, itching, runny nose, and watery eyes. It’s recommended to consult with a healthcare provider or an allergist for the best personalized advice regarding allergy medication.

While outdoor, understand that the pollen count varies by time and weather. Typically, the count is highest on warm, dry, breezy days and lowest when it’s chilly and wet. Limiting outdoor activities during high pollen count periods or wearing a wide-brimmed hat along with your glasses or sunglasses to provide extra protection could be beneficial.

Lastly, ensure that when you return indoors, wash your hands and rinse your eyes (using appropriate eye wash or saline solution) to remove any lingering pollen. This multi-pronged approach can help to significantly reduce eye irritation caused by pollen.
