So when i'm silenced or muffled, i realized that enemies can still see the first few seconds after i cast invisibilty , i thought that maybe it is intended that way as if invisibilty needs time to take full effect! however today while sneaking some skeavers spotted me, i was already muffled so i cast invisibilty now the eye was still open and the skeavers attacked me and when i hit one of them ( eye still open) i got sneak damage !!!! which is the glitch the fact that i got sneak damage or that they can still see me the first few seconds after i cast invisibilty ??
