The treatments could vary from home remedies to medical intervention.Seasonal AllergiesIf you have itchy eyes around the same time in the year, you may have seasonal allergies. You could be allergic to ragweed or something else that blooms during the season, releases pollen and gets into your eyes that time of the year.You may also get reactions like sneezing and nasal congestion. Allergic symptoms are also triggered by histamine, which is a compound released by cells to defend against allergens. It causes an inflammatory response, and itchy eyes are one of the common signs of it.So, what can you do?Pay attention to the local weather reports, look out for pollens.Keep your doors and windows locked.Take showers and wash clothes to keep pollen away.Wear a mask every time you stay outside.To counter your allergies, you can also use over-the-counter astihismine medications, which can be helpful for controlling symptoms.Perennial AllergiesThey are not like seasonal allergies, they are the ones that stay year-long. Things like mold, dust, and pet dander could be the reason that can trigger perennial eye allergies.You might be allergic to certain products around your home.
