1. Clean the viewfinder. Often I find them grimy and unclean.
2. "a diopter enables you to adjust the viewfinder to your eyesight. " so look for that adjustment.

First time poster here. I recently received a Sony DSC-HX100/HX100V as a hand-me-down and it seems that the viewfinder is blurry when I look into it. Th LCD screen works fine, the photos do not come out blurry and the camera's sensor which switches between the viewfinder and LCD screen all work perfectly. I tried resetting the camera multiple times to no avail.
Is this a simple fix or will I need to replace the view finder?
