Are these 2 prescriptions the same?

sudzs

It's a long story but around 9 months ago I had my eyes tested and got new glasses from my local optician. A few months later I bought a spare pair from one of the online opticians, using the same prescription (scanned and emailed to them). When I got the second pair I noticed that with them on I could read small print that was not so clear with the first pair. There is definitely a small difference between the 2 pairs.

I think it isn't advisable to alternate between 2 pairs of glasses that are different so I have just had the first pair looked at by an optician and he told me what prescription they are. (I should have brought the second pair to be done too but it was spur of the moment!)

Anyway, I'm hopeless at reading prescriptions so would really appreciate if someone could tell me if these 2 are the same or if they are different in any way. And if different, how would No. 1 be written if it were in the same form as No. 2?


Prescription 1:

Right:
Distance: +1.25, -0.50, 100.
Inter: +0.50
Read: +0.75

Left:
Distance: +1.50, -0.50, 90.
Inter: +0.50
Read: +0.75



Prescription 2:

Right: +1.50, -0.75, 105
Left: +1.75, -0.50, 90


Any advice appreciated!

It looks like No. 1 may be a varifocal and the other isn't. In other words one is for Distance and reading while the other is something in between, that is, neither perfect for distance nor reading. Hope that helps.

Thanks for the reply Foggles. No, the first one is for reading and computer work. It's not for a varifocal but it is to allow for both close and intermediate vision. (I think!) My old lenses this is replacing were from a prescription what was to allow me to look up from a book and look at the person across the room without too much distortion from the lens, if that makes sense. And prescription 1 is supposed to do the same.

So if you were to write prescription 1 in the same form as no.2 it's not the same is it? Basically, I have 2 pairs of glasses made from the same prescription but they are different!

I'd go back to my optician about it but I'm overseas at the moment and it's an effort to get to one at the moment so appreciate any advice here!

The first prescription is distance it shows an intermediate add +0.50 and a reading add+0.75 the second prescription has an extra 0.25 added to the sphere and cyl which makes no sense id question it.

I'm guessing that you are aged between 42-44 in which case both prescriptions are much of a muchness. Just depends on what you require them for. Do you feel you need help to see the Tv or for driving?
