This is an SE port of "Invisibility Eye Glitch Multifix-LE"

Total credit goes to "jimkaiseriv "



There are several approaches to fixing the invisibility eye glitch. One is a mesh approach, which works great for the player but not for other
Actors. Another is a scripted approach, which corrects all Actor's eyes
after an invisibility effect ends, but may cause brief visual disruption
for the player character.

I had to test this.  

Mesh fix:  
-- Works for Player without fail
-- Does not work on NPCs

Script fix:
-- Works immediately on NPCs (cannot see any glitched eyes)
-- Works slowly on Player (can see glitched eyes for a few moments)

Why not a dual solution?  Apply the mesh fix for the player and script for the NPC.

I couldn't agree more. This mod applies both fixes: the mesh fix for the
player, and the script fix for every other Actor. There is an MCM which
allows you to configure additional options for the script, including a
hotkey which applies the fix to all Actors within a distance of one
cell. This will correct the issue for any NPC currently experiencing the
glitch, and provides additional compatibility for invisibility effects
added by mods.

Script lag should not be an issue for anyone. There are no scripts which are run constantly. The scripts are attached
to spell effects that cause invisibility, and are triggered when the
effect ends. Besides checking for certain conditions, the only real
thing they do in most cases is call QueueNiNodeUpdate() on the Actor.

Some people report problems with the eye meshes provided by this mod. If you
want the benefit of this fix without the eye meshes, you should delete
the meshes and enable the script fix for the player in the MCM. Details
on what meshes to delete can be found in the comments section.

The scripted fix which can be done by hotkey (can be remapped in MCM) should work on any Invisibility Glitch i.e. any mod that creates vanilla or custom
invisibilty effects should be under the scripted fix by the hotkey.

Installation

Use your preferred mod manager to install, or simply copy the files to your Skyrim data folder.

Requires:

SKSE 

SkyUI


Compatibility

Fully compatible with all spell mods that use the vanilla invisibility
effects. New spells that use new effects will be compatible without a
patch as long as the effect is only applied to the player. New effects
that apply to other Actors will require a patch, or the use of the
configured hotkey.

Fully compatible with eye texture mods, as long as they don't change the meshes.

May not be fully compatible with characters using the YGNord race, or one
based on it. Testing done by Mr. Dave shows that the meshes used in the
eye fix may cause a bulging eye effect when zooming out, if combined
with this race (see the comments for details). As a workaround, the
meshes this mod adds can be safely deleted, and the scripted fix can be
applied to the player by changing a setting in the MCM. Note that this
issue is not present for Vanilla races, and has not been reported for
other race mods.
