Hi all,

I'm short sighted and always had an optician arrange the required specification when buying prescription frames/lens.

However, my Mother now requires reading glasses (i.e. long sighted) , and I wanted to buy a pair for her online, only....

I quickly became confused for what to enter in the diopter field when ordering, despite having her Boots prescription to hand which I paste below




For a pair of reading glasses only (not worn all the time, just for newspaper, phone, chopping veg, sewing, etc.) when needed to submit a diopter number, am I supposed to enter:

Sphere only?
or Reading Addition only?
Or both by adding them together?

I have tried to call Boots, who issued the above prescription, however...
8 phone calls over 2 working days and we've no luck in anyone picking up!

Thanks in advance - I'm sure many here are comfortable with ordering online already.
