There used to be some loups you could buy that were perfect and not too expensive, but I have not seen any of them in years, but I have not really been looking.
I had a pair for years that I don't even remember where i got them. Here is the trick for those that have trouble with optivisors. I had some lenses especially made to go in these frames that were mounted on a pair of eye glasses rims. there was an extension jutting out from the nose pieces of the glasses about 2 1/2 inches long.
They had a wheel between the lenses that would allow you to turn the wheel and the lenses would seperate or get further apart, or get closer together according to the direction you turn the wheel. this would allow you to be able to adjust for the distance between your eyes and your face dimensions.
Now, I am just industrious enough that I could make a pair of these if I so choosed, and I bet you guys could too. Of course you need two opposing threads on the wheel axel to make this work.
I used them with ten power lenses until they finally broke, but the setting was engrained in my mind, so I made a pair with the right seperation for me without the adjustment wheel. I still have them. They are lite, they don't interfere with your periferal vision, and you can look over them to find things on your bench.
If you have perscription glasses, you could make them where they were removable or attachable to your glasses. the only thing with this is, you have a double lense that sometimes might distort reality, depending on the power of the lenses.
I don't know if this will help anyone, but I thought I would throw it in to let you know that you are not limited to what is out there if you have the time to create and fabricate.
But then I made a lot of my gizmos back then, and once you have them, you have them. That was the only way you could get them, so fixtures for holding things etc. were often the geniuosy (sp) of the engraver.
