I have never had bloodshot eyes from just smoking the greens... but I have tried using visine to ease some of the dryness from being in a smokey room. I will say (from my experience, not saying it effects everyone this way) but when you use an eyedrop the heavy sleepy-eye and slighly delayed visual you can get from being REALY high is diminished somewhat with eyedrops. Possibly because your eyes are not as heavily filled with blood anylonger? Any thoughts or anyone else thats noticed this?
