srgallon,

Drifting has some good points but you may also be aggravating your neck. I wear tri-focal lens glasses and the head movement to find the correct lense area is problematic.

You may want to try icing your upper neck at the base of your skull during your breaks. A soft cold pack works great or you can make one with a seal-able/zip-lock plastic bag and water with 30 to 50% rubbing (isopropyl) alcohol. It prevents the water from freezing hard. Wrap the ice pack in a towel and ice for 10 minutes or so during each break.

I often will lean back in my chair so my 22 inch monitor is about a yard/meter or further away and I don't have to tilt my head to see.

Hope this helps.

My best to you.
