How Do I Order Reading Glasses from Progressive Prescription?

Question

I have a prescription for progressive lenses which I've filled through an on-line outlet.

Now I want to order a pair of reading glasses. But I don't know who to fill in the on-line order, given my prescription is for progressives.

Can anyone tell me how I can do it without getting my eyes re-tested?

Answer 1

You total the Sphere power and the ADD power. The cyl and axis will stay the same. Make sure you cross the zero if your sph power is a negative number. The ADD will always be positive.

I am an optical lab manager, so I am just curious as to how the website gets measurements on a progressive. I hope that an optician somewhere measured you in person. There is at most a 1mm tolerance for error in a progressive measurement.

Answer 2

It would be really amazing if the progressives work like they should.

It's impossible to guess at the measurements for the progressive height.

Even using the same frame on 6 people, there will be 6 different measurements.

Different noses , different widths, different bridge heights make a frame sit differently on everyone.

But I guess you will only get what you pay for.
