Magna-Flip Clip-On Flip-Up Magnifiers – Convert Distance Glasses to Reading & Computer Glasses +3.00 Diopter – Perfect for Reading, Crafting & Computer Work

I ordered these mostly for reading music as a fill-in pianist in my church. I wear a strong prescription with a progressive bifocal, but I have found myself struggling to see/work the bifocal particularly re: reading music for piano. These came last week and this Sunday, I was able to read the music comfortably and clearly. I ordered 3.00 diopter after having had similar success with a 2.50 pair for reading at home. The earlier ones were larger than I liked, so I ordered the small size and they were ideal with my glasses. Less bulky/heavy, as result, too. These flip-up magnifying glasses already have been a huge blessing and will continue to be! (Note: If you're not sure about the magnification, drugstores and similar places have many different levels in regular OTC reading glasses that you can, in-store, test: e.g., overlay above your glasses. Check varying distances and types of print, etc.)
