Magnifying Glass and Microscopes

I have a 15x magnifying glass, it works okay, but you can't really tell if the trics are clear, or foggy, or amber.

What would be the minimum "x" number you would need to see the trics clearly? I'm looking at a few on Ebay,
and they're only a few dollars, and some even with free shipping. The one linked below is 60x. Is that enough?

Here's pics of what my 15x can do (and a decent camera) (btw, that pic does that bud no justice):

I have a 35x that works well enough, that 60x should be more then enough to get a decent view.

According to "Mr. Rock and Roll Through and Through" David Brent, 60X-100X should do the job.

ive just ordered that same one, ill let you know what its like when i get it. delivery takes forever tho.

I'd like to get at least 60x, even up to 200x if I can find one.
Ebay does have quite the selection to choose from.
