Surgeons typically use loupes with a magnification power of 2.5x to 3.5x. Loupes are magnifying glasses that are worn by dentists and surgeons to help them see small details more clearly.

The magnification power of the loupes refers to the level of magnification that the lenses provide. Higher magnification powers can make small details appear larger, but they can also make it more difficult to see the overall picture.

Surgeons often prefer to use loupes with a lower magnification power, which provides a wider field of view and allows them to see more of the surrounding area. This can be helpful during surgeries, where it is important to have a good overall view of the surgical site.
