Claim: A major source of bad computer posture is caused by tiny screen fonts, especially those that don't scale with resolution (such as Windows UI fonts). Control Panel | Display Properties | Appearance | Font Size. I always set mine to Large Fonts or bigger. Try increasing the fonts in your browser too. Finally, make sure your monitor's DPI is configured properly. Control Panel | Display Properties | Settings | Advanced | DPI Setting. Your eyes will thank you. Your back will too. (Here's one area where Linux blows Windows away. The Windows UI does not scale well at all.)
