Our silkie fava has an eye issue?

This is fava our 3 month old silkie baby. She had been eating and drinking/ acting like a silkie. Healthy up to today.

First pic is left eye that’s reg. Right eye is weird. Never noticed anything wrong before but this afternoon it looks smaller than the other eye. Not only that I think she has some vision loss because when I cut her feathers back she didn’t move when the scissors came close.

No other chickens seem to have eye issues in the flock.

My question is:
Does this like a serious medical issue?
Is the eye « watering » or is it possible it’s infected?

First sick or different chicken we’ve had.
