Based on your description, you've had Juvederm injected to the lines formed from the corners of your mouth down. The product doesn't migrate up to your eyes - from below your mouth so no, in your case it's highly unlikely your blurry and watery eyes are as a result of Juvederm injections.

Eye problem after filler in marionette lines
Your symptoms are not likely from the procedure. You should see an ophthalmologist or oculoplastic surgeon.
Juvederm injections causing blurry vision and watery eyes?
No, these issues are not related. Injections into the marionette lines would not affect the eye area. Additionally if you were having some type of allergy to the Juvederm, you'd have much more than blurry and watery eyes - like a skin reaction in the area injected, redness and flushing, itchy skin, and all kinds of other issues. Something else is causing your eye issues, not the Juvederm.
