Effects of hanging skin over the eyes on eye exam

I lost 80 pounds in 5 months 10 years ago. So the skin on my face
became loose and settled in big blobs under my eyebrows. So my
eyelids are no longer visible and the weight of the skin keeps my eyes
closed pretty far. It never went away. It looks like swelling, but
it's just a mass of loose skin and it all disappears when I raise my
eyebrows way up. It just occurred to me that this is exactly when I
started having problems with every eyeglass prescription being much
too strong. At first I mistakenly thought it was the level of light
during the exam. But I experimented with some tinted sunglasses and
found I was totally wrong about that.

I'm farsighted and the prescription I just just got a few weeks ago
was much too strong (as usual). So he cut each sphere by .50, but
they're still too strong. But I just noticed today that when I raise
my eyebrows, the focusing improves.

Please tell me if this makes any sense at all. Is it possible that
when I push my head into the head rest on the machine, all of the
weight of that loose skin is being removed from the eyeballs, and that
this is somehow making the shape of the eyeballs a better match for
the prescription?

If that's possible, then how would you all deal with that during the
eye exam?

I'm sorry to be a pain in the neck. But this is really frustrating.

 

I guess I would deal with it, by eliminating it. I had two friends,
both of whom had the excess eyelid skid problem I.D.ed by their
eyedocs.
In one case, the doctor did a little plastic surgery and removed it;
in the other case, the individual was referred to a plastic surgeon
who removed the excess skin.
