Whats an average trich head size 150microns - x10 = 1.5mm in the loupe at magnification.
x30 = just under half a centimeter for each trich and a centimeter at x60 magnification.
Id say a x10 is quite a wide field and a x60 will be closer to individual trichs.
Suprisingly i can spot amber patches with my eyes no magnification so with some good eyes you should already be able to see whats going on until your loupe arrives.
