Lenscrafter: New Glasses, 1.67 index, red edges, hard to focus

I recently brought my new pair of glasses at Lenscrafter because of
their 30 days return policy. My prescription is about -7.0 on both
eyes with a bit of astigmatism in one. With these glasses I had hi-
index 1.67 lenses which are suppose to be from Essilor but the coating
is their own Scotchgard Protector.

Maybe I am being picky but it is really annoying seeing red outlines
along edges. I was wondering if this is due to chromatic aberration. I
tried complaining to Lenscrafter but I don't think that my optometrist
has my prescription right either because it is hard to focus on
traffic signs in intersections with 4 lanes. I stand on one side, and
it is difficult to read the time when left turns aren't allowed. I had
the optometrist reexam me, and he gave me a new prescription but it
didn't seem to help.

I don't know what was the index on my previous pair of glasses but the
thickness of the lens is about the same. Even when I stare at the same
point, as I tilt my head left and right, the vision changes.

With my prescription would the lenes be much thicker if I switch from
1.67 index to 1.6 index? Is the problem in the index of the lens, the
quality of the lens, or the coating on the lenses.

Side question: Nikon HCC ICE or Essilor Crizal Alize. I know these two
are just coatings but if you get the Nikon/Essilor coatings are you
likely to get the Nikon/Essilor lenses. Which is better?

Most likely

If you have astigmatism, expect the vision to be worse with head
tilting. Also will happen with aspheric design single vision lenses
and with progressives.
