Almost two years ago I purchased a new set of frames and lenses from a
local independent optical shop.  I asked for Seiko high index lenses.
There were some problems when initially made and one lens had to be
remade.  Recently I noticed the coating starting to wear off one lens.
Looking closer at the lenses I noticed one has a slight green tint,
while the other has a slight purple tint.  This pair of glasses has
never quite seemed right, my vision has always seemed a bit skewed.
Are the two different colors proof that one of them is not Seiko?
Would two different brand lenses possibly affect my vision?  I'm no
longer in the same town, so I can't go ask for them to remedy it.  Is
it unreasonable to ask them to refund the cost of one lens?

Thanks for any info.
