I'm guessing the eye you keep closed is what's bothering you which will improve over time as it will strengthen the eye lid muscles. You'll have less eyestrain if you learn to use the glass without closing the other eye. |

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. |
