Finally I figured it out,the issue is on the armature.I rolled the "Head" bone and all its parent bone -90 degrees,now the eyes are looking at the right place.This issue stuck me one week.

look like this?:

$attachment "eyes" "Head" 0 -0.5 20.9236 absolute

I have already tried ,nothing changed.

What happens if you use localViewTargetFactor and the eyes_updown and eyes_leftright sliders?

The pupils move a little distance but still facing the left.

This is my reference file made by Blender

The eyes works good in HLMV, but they staring at the left side in SFM. What's wrong?
