weird PAL problem

hi i used to wear +1.25 od 1+.25 os with 2.25 add PAL glasses and had
no problem but slight blurry vision in the right eye. i had my eyes
examine and my new rx was +1.75 od and +1.25 os with 2.25 add. the
frame i pick for the new PAL glasses was slight smaller than the old
one. i now have this weird problem, i'm getting a smaller viewing area
in the right eye but no problem in the left eye. did increasing my rx
in the right caused in smaller viewing area? i have to fish around to
find clear area to read our of my right eye, the new lenses are made
by instinctive, i'm not sure what the old leneses were......TIA

 

Assuming the specs are fitted correctly: If you have to "hunt around"
for the proper optics, it means the proper optics is not where it should
be. Wrong position of the corridor.

PALs differ by design and by accuracy of fitting. I'd suggest bring them
back and try again.

I have four pair: all fitted perfectly, all have their strengths and
weaknesses. I prefer contact lenses!

Getting the right Rx, and the right lens design, and the right fitting
(frame and lens) for PALs is pretty much voodoo.

 

Wrong

It's a combination of mathematics, physical optics, understanding the
user's needs and workspace, choosing the appropriate lens design and
accommodating that data into a frame that satisfies the criteria.

And even then, sometimes the user is not going to be happy. You must
accept that PALs, even the best and most carefully designed PALs are
still a compromise in optics.

Let me rephrase that..

Trying to find the right OD and/or Optician who sill properly determine the
Rx, select the best lens and frame, and do the fitting correctly for PAL's,
is voodoo.
