Hi. I'm online and happy to answer your question today.
the best thing to do for your eyes during a systemic issue like a cold or flu is to soothe them with artificial tears frequently throughout the day. There are many brand names available, such as refresh tears, natural tears etc. The least expensive of them work just fine. :)
Also, use cold compresses to help reduce the swelling and edema.
As your cold resolves so should your ocular symptoms.
Is there anything else you would like to discuss at this point or have all your questions been answered to your satisfaction?
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. And please let me know if the rating system gives you any troubles. Thanks in advance, Dr. Rick MD FACS
