I'm assuming that it's the mods: Better PvP Mod, CodeChickenCore, Extra Utilities, Gravestone mod, Magical Crops, Mantle, Not Engough Items, Optifine, Securitycraft, Tinker's Construct and finally Vamprirism. Since I often walk in the dark because of vampirism, I need the night vision very urgently. Does anyone have an idea? No matter how I try, per drank, per command, per vampirism skills, it just does not work!

Shader in it?

Yes. I turn it off and then I look.
