progressive enquery

I have a prescription for progressive lenses and it is written like this:
vision de loin:
od:
(-5 -0,75) +0,00
Os:
(175 -1,50) -0,25

vision de pres:
Od: (add +1,75)
(-5 -0,75) +1,75

Os: (add +1,75)
(175 -1,50) +1,50

I would like to ask if anyone knows what are the values between brakets? It is a prescription taken by an ophtalmologist.

What I'm assuming is this would be written in the US as:
Distance
OD: pl -0.75 x 005
OS: -0.25 - 1.50 x 175
+1.75 ADD

Near
OD: +1.75 - 0.75 x 005
OS: +1.50 - 1.50 x 175

The parentheses must separate the cylinder component from the sphere .... and I would imagine that as an optometrist, you would know whether an ophthalmologist would be able to take this.

The prescription is from a French ophtalmologist, and I think that's not the solution. It might be some measurements at keratometry ...or other test?

I assumed that this was a spectacle Rx namely because vision de loin means "distance vision" and vision de pres means "near vision". Also, Keratometry readings wouldn't have values this low; afterall, it is measuring the cornea... ie: we should be seeing values closer to the 40-50D range. Note: I misread what you wrote earlier. I thought your post said "is it a prescription taken by an ophthalmologist ?" rather than "it is a prescription..." However, I still stick by my assessment. It doesn't seem like it could be anything else. Please someone repost here if they disagree with me.

the way they write it is so alien to us.
Our way is alien to them too,. haha
