Q: How do you know what strength you need?

Hi, have you had reading glasses before? You can try them out at a store, you can get an optometrist to help you figure out the strength you need, or you can use this printed sheet to figure it out: https://www.thinoptics.com/media/Reading-Glasses-Strength-Test.pdf Or I suppose you can make a calculated guess about the strength you need. If you just recently noticed you need reading glasses (maybe you’re around 38-40 years old—that’s when most people first notice) but it doesn’t seem like a dire need yet, then you probably need 1.5 or possibly 1.75. I started with 1.5 when I was in my early 40s. I’m in my mid-60s now, and my reading glasses are 2.5. That’s about how the need for increases in strength typically progresses. Good luck! These are excellent reading glasses, especially for the price.
