And generally speaking, common symptoms include itching and burning of the eyelid margins and conjunctival irritation with lacrimation, photosensitivity, and foreign body sensation. And when t occurs, you should avoid touching eyes unless hands are clean. Also, you can put a damp, warm washcloth held over the a few times a day. That can be called as warm compresses. In this way, it can help relieve swelling, itching and redness. Of course, there are also some specific treatments including antimicrobials.
