The blurry screen isn't a glitch as most think. It's related to your "Health." You have a blood level (depicted by the color desaturation) and a health level (depicted by blurriness). You can only regen your health by having the Healing/Healthy status. There is a guy who did an extensive video explanation of the health system on YouTube. So by doing that "trick" you are basically ignoring that you have critically low health & will die that much easier. Eat dem beans!!!
