Wearing +1.00 doesn't change the eyes. "Dependence" means you get used to
seeing without effort.

A child might not notice any benefit from +1.00 glasses. At age 50, that
same +1.00 would mean the difference between comfort and headache.

most eye have some small refraction errors within that range.

Dear Robert,

Subject: Are you going to fill the prescription.

Question: What did the optometrist say was your
problem?

Do you think you have a serious medical problem that
these prescription glasses will solve?

What was your complaint before you went to
this doctor for assistance?

Thanks for the information!

Otis

One step stronger in the left, half step in the right, along with some axis
tweaking.

Hi Robert, Michael

Thanks for the url, I had done the conversion myself, but not knowing
anything about optics i cant judge how significant the difference is.

Are they different enough to warrant me getting another test?

Thanks

Hi,

I recently had my eyes tested twice (because i didnt trust the first
optician)

And these are my two prescriptions:

Sph Cyl Axis
+0.25 +0.75 180
+0.25 +0.75 170

+1 -0.5 100
+1.25 -0.75 70

Can someone please tell me if these are significantly different from
each other (so i know if i need a third opinion)

Thanks
