Treating Monitor-Related Eye Strain?

bergeron76 asks: "Like many of you, I look at CRT and LCD displays constantly when I'm at work and when I'm at home (and even when I'm in my car). As a result, I was wondering if any of you have any neat ideas or ways to help reduce eye strain and dryness while looking at displays continuously? I've tried vitamins, eye drops, increased blinking, and combinations of glasses / contacts with little success thus far. People make assumptions about me because my eyes are constantly blood-shot, and I'm wondering what I can do to heal my eyes? I recently heard about Punctum Plugs and was wondering if anyone has had any experience with them and if they're worth the cost. They're little plugs that reduce the size of your tear ducts so your eyes retain more fluid and stay 'lubed'. Does anyone have any experiences with these or have any other recommendations for reducing eye strain and dryness (aside from not computing)?"
