Our level of magnification, 2x at a 16″ reading distance, is designed to maximize the performance of the magnifying telescopes for multiple activities. This is very similar to what you see dentists wearing.
DO NOT CONFUSE 2X WITH YOUR +2.00 READER–they are not the same thing. A +2.00 (2 diopter) reader is not the same magnification level as a 2x magnifying telescope. 2x is roughly equivalent to a +8.00 (8 diopter) reader. A +8.00 reader is not commercially sold and would have such a short working distance that it would be unusable. The magnifying telescopes work WITH your own reading correction (they drop down in front of your reading correction), boosting the overall magnification you have.
2x magnifying telescopes doubles the image size but from a comfortable, ergonomic working distance. It provides power, distance and flexibility. As magnification increases, the field depths decrease, which can be limiting for many crafts.
