Hi Everyone! Well, got the latest Windows 10 cumulative updates (as well as a security update that didn't even work, failed multiple times -- for many millions of users as well) and my eye strain has returned. So once again I'm using one of my trusty patches to help remedy the situation. Wish me luck. It's worked before and I know it will again. Also had some new LED lights installed at my work a few days ago, perhaps that triggered it?? Very annoying. I hate new technology!
