My sister-in-law works in the eye industry. She does the FDA work for the new equipment and procedures for eyes. We were talking about dry eyes this weekend. They have a relatively new procedure that can be done for dry eyes. Unfortunately, I can't remember the name of it at the moment. Separate and apart from that procedure, she said dries eyes are often not caused by lack of tears, but by lack of oil. You can make lots of tears, but they just evaporate if you don't have the necessary film of oil on the eye. The oil glands get blocked. So, to unblock them you can put a heating pad on your eyelids, then massage the eyelids and that will clear up the oil glands. Apparently, there are heated eye masks specifically for this purpose. I haven't looked into it yet, but I do plan to. She said if you're using one of those things that you put in the microwave to heat up, then be careful not to get it too hot because that can damage your eyes. The electric one is supposed to get the heat just right.
