Are you leaning forward to see what you're working on, or what? If it's a sight issue, you can put a couple of door stops behind your machine to lift the back up so you can better see what you're doing. Much better for those of us with bi/tri-focals. You might also try moving the machine closer to you if possible. Just a few thoughts.
Oh, and are you sitting up high enough on the chair to best see your work? If not, try that. It raising your chair makes your feet dangle, then put an appropriate sized box under your feet. Our bodies need to be at 90° angles at our arms, hips and knees. What's your angle? LOL
Hope this helps, :D
