glasses people or mad cow question (1 Viewer)

[belljr]

So I got reading glasses 3 weeks ago. It's the first time in my life I needed glasses. I'm 43 doctor said is was normal. So my sphere is 1.5 for both. And cylinder is -.25. With an axis number. I know those last 2 are for my astigmatism.

My question, if i want to pick up some cheap readers as backup to my prescription glasses, does the sphere number = magnification?

I believe that refers to diopters.

I would want to know if your Rx is +1.50, or is that the add? At 43, I'd say +1.00 or 1.25.

 

[Mad Cow]

If the overall Rx is +1.50, then you would probably need closer to 2.00 or 2.25.

This is what my paper says

Od sphere +1.50 cyl -0.25 axis 116

od sphere +1.50 cyl -0.25 axis 088

I read online that I should take half of the cyl and add or subtract to the sphere number.

I don't have any other numbers

just want to get some cheap backups

Go to the drugstore, pick up a pair, put them on and see how they work. Pick up a different pair with a different magnification and see if they're better or worse. Repeat until you find the ones that work best.

When did he say to use them? All of the time, or just when reading?

just reading. Or sitting at my computer

Then +1.50 is your power.
