Dear Power Wrap,

Could you supply us with your current distant prescription?

Your add power on a progressive is on top of your distance power, so unless
your distance power is plano (plain glass), you will need something other
than +2.25 for readers.

You should not buy reading glasses online unless you know what power is
needed. Go to a discount store where they sell these on a rack and find the
best power for you at the distance you need. If you don't like the reading
glasses at the discount store, then you can order some online with the same
reading power. Trying to guess what power you need is good way to waste
money.

However, most people have at least a slight astigmatism, and off-the-shelf
glasses (non-Rx) cannot correct for this. You should be able to tell whether
you have an astigmatism correction in your current progressives by looking
at the cylinder power and axis (degrees) on your Rx.

It should be.

If you're 52+, the +2.25 add should be clearest at about 18" (1/2.25 in
meters).

If you want clearest vision at 24 inches, there's no specific add for that.
+1.75 works out to 22.5" and +1.50 is 26.25. Computers and bulletin boards
and name tags are often further away than 24" and you'd switch glasses for
taking out splinters, so less is probably better than more. I've never seen
a 1.87 add.

Report the right and left distance prescription as they are, with a +1.50
add. Make it crystal clear that you want the rx converted to single-vision
reading glasses.

For idiot-proofing, just add the "add" to the *first* number (sphere) in
each eye and report that as the single-vision rx with the near PD only.

If you want to do that, post your Rx here so we can double-check it for you.

It's simple enough, but ordering online it's best to assume monkeys will be
involved in the process somewhere.
