My new eyeglasses are burning very badly. My old or existing pair, very minimal. Single vision. The new prescription has not changed in one eye and very minor in the other. I've had this problem before for different reasons: prescription too perfect, centers off and lastly (believe it or not) supposedly cheap plastic. The "cheap plastic", everything else checked out and the optician admitted to the inexpensive plastic and changed it out and the burning went away. That's the existing pair I have now. That was 10 years ago and that optician is gone. With this new pair we tried polycarbonate and plastic. We used Essilor in both cases. That should be ok. Both burned. My old pair has vinyl nose pads, so does the new pair. They both are coated. The old and the new are both metal frames. By process of elimination, what's left? I'm wondering about the optician's cleaning solution. Whatever is happening is very, very strange and unusual. I've ran this by over a dozen opticians so far. All, no thoughts or comments. Nothing on the net either.
