Are you sure about that? If that were correct, a person with perfect

eyesight would need a correction lens just for use with the magnifier.

Yes that is correct. Since the magnifier is basically bring the image closer to your eye then a naked VF. Closer to my eye I need stronger reading glasses.

Some one with perfect vision doesn't need glass to see far or close up so the difference in the distance the magnifier brings VF image to there eye there eyes can adjust. No diopter need.

No it is because the magnifier brings the R/VF image closer to your eye then the fixed distance of 7 feet (2 meters). I use a +1 diopter on the naked VF and a +1.5 when I use a X1.25 magnifier

 

if i could thank you more than once, i would!

 

that really helps me to know what to look for when checking out dioptres now :D

 

i don't suppose you have the X1.4 magnifier as well?

No all I have is the x1.25. But I must say that once I got the correct diopter for the naked VF and the VF was properly adjusted for focusing distance and most importantly vertical alignment I no longer needed a magnifier to focus longer lenses accurately. So I haven't used my x1.25 in over 2 years. It just sits in the bag.
