A friend of mine is legally blind with a form of macular(spelling) degeneration. He is able to see some from the perifery of both eyes ie: straight ahead vision is gone in both eyes. He can read slowly using a common storebought monocular 10x/21mm (I think).This thing was prescribed to him by an optometrist. The eyelens is very small. I think that something else, even custom made would work much better.Does anyone have any ideas as to what would work more effectively? such as a converted uwa eyepiece or a source for such an item. Any help would be greatly appreciated. Please pass this on if you can.Thanks in advance for your help, Tony

You might want to try a variety of scope eyepieces, turned upside down. I use a flipped over 20mm Plossl when I need high magnification to inspect solder joints (I unscrew the barrel so I can get my eye right up to the field stop).
An inexpensive 2" EP, maybe a 30mm Q70 or the like, would probably give a wider field and more eye relief.
Hope this helps,
Tim

These monoculars also need to be small and light-weight,
as they must be carried all the time. A 2 pound scope
built around a big Nagler eyepiece is not going to be
very practical. I expect it will be hard to beat a
small well-made pocket monocular by Zeiss, etc.
