These old eyes are not what they used to be and even with prescription reading glasses some close work of late is getting more and more difficult. I did a little research and came up with the following which were delivered this afternoon by Mr.Amazon. They are going to make things so much easier. They are light and comfy and just flip down over the top of my reading specs.
The general advice given on this sort of product is that most people are happy with the 2.5 x magnification which should give a focal length of 8” and yes, without my specs on 8” is about right. However, the “picture” for want of a better word is not so clear. With reading specs on though (they are about 4 x with a slight correction to one eye) the focal length becomes more like 5” but the “picture” is magnified just so and is pin sharp.
I took a flier on choosing the 2.5 x option and luckily I chose correctly.
Not a cheap item I know but boy this is pukka kit.

PS I tried to include a link but it keeps coming up with my personal details so I am afraid a search on the following on Amazon UK will have to do:
