Ray transparency mirroring?

I have a scene with a wine glass I am working on and the glass material looks
very good except that the top part is mirroring the surroundings. I don’t have ray mirror on so what is causing this?

Ray Transparency simulates the bending of light as it passes through transparent objects. What you are seeing is light being refracted from different angles. Reduce the IOR factor to reduce the distortion.

I just adjusted it now and it worked! The original index of refraction value was 1.52 which is the real refraction of glass but I think Blender over-refracted everything. Thanks so much RamboBaby. :smiley:
