Why do eyes itch in spring?

In addition to the common dry eye problem, itchy eyes may also be caused by allergic conjunctivitis. Allergic conjunctivitis is mainly manifested by itchy eyes, red and swollen eyelids, conjunctiva (white eyeball) congestion and edema, increased tears or white secretions; some patients also have symptoms such as nasal congestion, itchy nose, clear runny nose, and sneezing.

When spring comes and flowers bloom, the amount of pollen in the air increases and can easily invade people's eyes, skin and respiratory system when blown by the wind. People with allergies are at a high risk.

Allergic conjunctivitis, also known as allergic conjunctivitis, is a hypersensitivity reaction of the conjunctiva to external allergens. It is mainly manifested by a series of symptoms such as itchy eyes, increased filamentous secretions, and red eyes.

There are many allergens that cause allergic conjunctivitis, which are widely present in our lives, such as pollen and catkins in spring, cosmetics, contact lenses and their care solutions that we come into contact with on a daily basis, etc. In addition, animal hair, dust mites and dust particles in the air may also cause allergic conjunctivitis.

0 1How to prevent allergic conjunctivitis?
The most fundamental preventive measure for allergic conjunctivitis is to "stay away from allergens."

1. Improve the home environment

For example, clean the room and wash the bedding regularly to avoid the production of large numbers of dust mites.

2. Pay attention to personal hygiene and eye hygiene

Wash your hands and face frequently, do not rub your eyes with your hands, and wear a mask and goggles in an environment with a lot of hair, dust, and pollen.

3. Reduce outdoor activities

Avoid staying in the countryside or outdoors for a long time during the pollen season. In case of severe weather such as haze and dust, pay special attention to protecting your eyes to prevent allergic substances from entering your eyes. People with allergic constitutions should try to reduce going out. They can order mast cell stabilizers in advance to prevent allergic conjunctivitis and change clothes and shoes in time after returning home.

4. Wear contact lenses less often

The contact lenses themselves or the solution used to clean and soak them may also be allergens. Therefore, it is best not to wear contact lenses, especially cosmetic contact lenses. If you must wear them, you should try to shorten the wearing time, replace them with high-quality lenses, and use qualified care solutions.

02How to treat allergic conjunctivitis?

Once an allergic reaction occurs, if the symptoms are mild, you can apply artificial tears locally to flush and dilute the allergens, or use cold compresses on the eyes to shrink local blood vessels, reduce the leakage of substances in the blood vessels, and alleviate symptoms. If the symptoms worsen, it is recommended to go to a regular medical institution for treatment in time to avoid worsening of the situation.
