Magnifying Glass Sticker

I'm always interested in fine print. A lot of the time its the E numbers in food written in really small lettering on small jars and packages. Some are so small you need a magnifying glass and a bright e.g. kitchen light to read the print.

Failing good light, a powerful LED torch is a great way to add that extra F-Stop to your iris to make using a magnifying glass that much easier. But over time it becomes natural to move in the environment to position a light source over the shoulder and use a magnifying glass.

This is not suitable for checking out potential melanomas on a beach.

       This won't work very well. Next time you use a magnifying glass, lay it flat on the thing you're trying to read, and you'll note that it's not very effective.

       Even a Fresnel lens needs the same amount of distance between the object and the lens.
