I still have 20/20 vision but that's meaningless for coin inspection and I need reading glasses to see anything close. No aid is perfect, so I have an assortment depending on my intent: 10X Hastings triplet, 7X Belomo triplet, Optivisor jeweler's headset, Leuchtturn USB camera, 3" dome magnifier, computer tethered macro-lens camera, and some Sherlock Holmes type magnifiers. Love the Belomo for quality, convenience and transportability. The wife and kids laugh at the headset, but that allows hands-free viewing. Hi-res viewing on a monitor is a luxury, and often I see things unnoticed via loupe. No matter what I'm using though causes some eye strain, so I'm careful to take breaks. I want to photograph my entire collection and just look at the screen but that will have to wait for retirement.

I might have to try one. My next purchase will be a Sherlock magnifying glass and then maybe a quality triplet down the road. Thanks for the ideas. |

I photograph all my coins with a macro lens and post them online so I can look at them with my computer whenever and wherever I want. That's what I do, except I don't put them online, just in files on the disk. Macro lenses are good up to 3x or so. For closeups at 4x and above, I photograph them with microscope objectives. I never go anywhere near 30x or 60x -- 10x is my maximum magnification, which is ideally will resolve down to about 1 micron or so. |

First of all I use my eyes but after all I also got a jewelers loupe to check on very tiny details.

10x here. I seem to have misplaced it, though...

For casual viewing I just put on a pair of readers and enjoy. It is much more comfortable than having to look down out of my normal glasses.
For closeup examination I use a 10x loupe, but that is only for certain things and not all the time.

Just wanted to add:regardless of what power or lens size, you need to get quality. A clear view as opposed to a blurry view makes a lot of difference on your eyes.A glass lens is better then plastic,Hastings is better then Coddington. John1  |

I decided to pick up a 4x glass with a large viewing area. It's really worked well for casual viewing. I still have to use my loupe to inspect all of my various milk spots, cracks, bag marks and imperfections! On second thought, maybe I should put the loupe away.  |

I use a 20x 21mm.
not sure of the maker as I have worn of the name. I like it better than my 10x that cost me much more, but then people are always telling me I am strange.

I use a cheap jeweler's headset I picked up from Harbor Freight. It's ok but the lenses are crap so I've been thinking about picking up a nice loupe when I want to get a clearer view.

It depends for what reason you may want to look at your collection.
For long distance I do not need glasses; for reading I use 2x glasses.
If I want to have a general look at my collection and review it as a whole, I use 2.5x glasses.
If I want to see individual coins moer closely, I use 3x glasses.
If I want to look at some minor detail on a coin, Sush as the shape or position of a mint mark, I use a 10x loupe.
For such detail, I also use a 10x cloth examination lens, which has three elements in two groups. The advantage of this is that it has a far greater depth of field compared to a loupe, with one element lens only.
With the cloth examination lens, it is possible to have all the coin in focus, even when viewing it from a 45 degree angle.

I like to see the entire coin at once as others have stated. I like to use a strong pair of reading glasses that you can pickup at Walgreens or any other pharmacy. Right now I use ones that are 3.25 strength. I do have a 10x loupe but I don't end up using a whole lot. |
