Can I Just Buy Over The Counter Reading Glasses Instead Of Filling My Glasses Rx?

I just got a prescription for glasses- Dr said that I should use them anytime I am reading, on the computer, watching tv etc. My rx is +1.25 in both eyes and astigmatism in my right eye only -50. Would I be able to buy over the counter reading glasses and get the same results?
Yes, if your reading add is +1.25 you can save a lot of money by purchasing reading glasses in that power, vision wouldn’t be absolutely “perfect”, but you will be able to get along quite well with inexpensive “readers”.
You have this camera. A normal camera, when you move the focus all the way out, so there’s no power. To focus closer you have to add power to the lens. The amount of power depends on how close you want the lens to focus. (P=1/d where d is in meters)
So if you put in a +1.00, you’d be focused at a meter away.
If you wanted to focus at a half meter…+2.00
third of a meter +3.00
fifth of a meter +5.00
etc.
but YOU, don’t have a normal camera. You have a weak camera. Soooooo you need to add some power just to see at distance. You need to add +1.25 diopters and you are focused at distance, infinity, far away, out there, way out there.
But to see close now, you have to add some more power. To see a meter away, you’d ad a +1.00 on top of the distance one and you’d be focused at a meter. the total power would be the 1.25 plus the 1.00 or 2.25.
So, if you want to just get some readers, and you are far sighted that much (+1.25), get readers that are about +2.00 or so. You’ll be more comfortable, you’ll still have some depth of focus to play with (computer to book and back).
And it IS cheaper….
When you start getting headaches, let us know. Someone on this forum will know how to expain the reason. But you might not. I have all sorts of Costco ‘readers’ for backup glasses and they work just fine. Cost is $18.00 for 3 pairs.
Yes, but your right eye may not be as clear. A -0.50 cylinder is not a strong astigmatism correction, but like I said your right eye may be off a little.
You should be able to. I don’t know about watching tv with them though. They are for close up stuff like reading and computer.
