You say -  " I have been wearing progressives for years and never give it a thought now."

I never had any trouble - right from the start. Mine were prescribed after cataract surgery, two weeks after allowing the cataract surgery to 'settle'.

They put them on my face and said look out the window - tell us what you see.

I said - "A Split image that is just coming together!"    Brain sorted difference from two eyes - never any problem.

My glasses live on my face all day.
