Is there much difference between 1.5 and 1.75 reading glasses?
Bottom line: if you use 1.75 now, either 1.5 or 2 will work. 1.5 is less power and your clear focus range will be farther away. Whereas with 2 the range will be a little closer. I bet you won’t even notice the difference.
What does 7x magnification mean?
The first number, including the x, represents magnification or “power”. This tells the degree to which the object observed is enlarged. For example, a 7x binocular makes an object appear seven times closer than when viewed by the naked eye.

The X (times) factor of a magnifying glass refers to how much it magnifies. An average magnifying glass makes objects look 2 or 3 times bigger, which means it magnifies 2X or 3X.
What is magnification in glasses?
Magnification power is indicated by a number and the letter “X,” which simply stands for “times.” If a magnifying glass has a power of 2X, then the glass will magnify an object or printed type to twice its actual size. A magnifying glass for general use will have a power of 2X or 3X.

What does 4x magnification mean?
Scanning Objective Lens (4x) A scanning objective lens provides the lowest magnification power of all objective lenses. 4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.2020-03-16
What is the best magnification for a magnifying glass?

A negative number represents nearsightedness, while a positive number means farsightedness. The higher the number of diopters, the stronger the power of the glasses.
