This article is about the shader. For the preceding shader, see Eyes. For the QC property of $model, see Eyeball./ For the tool, see qc_eyes.
EyeRefract It is used to create realistic eyes, which are affected by map lighting and dynamic lighting, such as those from flashlights. This shader is a successor to the Eyes shader from 
Half-Life 2 .
Bug:Although this shader has support for $emissiveblend, it is not fully implemented and does not work properly. [todo tested in ?]Bug:The shader doesn't work in Counter-Strike: Global Offensive. Eyes always directed to map center. Standard models use static eyes [todo tested in ?]Shader Parameters
