One of the stranger symptoms of TMJ issues is vision problems such as Eye pain and Tearing/Reddening of the eye. Interestingly both of these are caused by the infamous SCM muscle trigger points which can cause a whole host of problems.
Also the Splenius Capitis muscles can also cause eye problems such as blurriness and eye sensitivity and eye pain.
