I found my grandpa’s Sherlock Holmes magnifying glass the other day. It brought back a flood of memories of when I was a child. I can clearly remember how playing with fire was fun and exciting. Little did I realize back then just how dangerous it was. We used to take our grandpa’s magnifier outside on a sunny day to burn leaves and paper.

We even had competitions on who would have ignition first. We didn’t understand exactly how it worked, and didn’t care much, we thought it was magical. Some boys would act strong and hold their hands under the glass to let the sun burn their skin. This was seen as an act of bravery. Those days were so carefree.

I never really gave it the time to day to find out a bit more about the humble magnifying glass. So I asked around and was told that it was written about as far as 1021. How to magnify something would greatly depend on where you hold the lends in relation to the object. The closer you hold it to let’s say a word, the less magnification happens. The further away it is held you get a larger looking image.

There a two methods for getting the optimum use from the lens. You could hold it close to your eye and move up close to the object using your eye and lens and the same time. The other method is you could hold the lens close to the object and adjust the focal point with your hand until you reach a desired magnification. This way is not dependent on the eye but on the distance of the lens to the object.

It’s really too technical to explain exactly how it is measured and really I don’t think you are that interested. So all I will say is this; it works when light passes through a curved lens and this light then changes it’s speed and as it changes it’s speed so it kind of bends the light to give us the optical illusion of an enlarged object.

How it actually works is when light passes through the lens, then it’s speed also changes. This action bends the light whereby making the object look larger (because only the light from a small area is focused). The framed lens is usually mounted to a stand and keeping the lens at the right distance from the table, and therefore at the right distance from the object on the table. Some magnifying glasses are foldable (from the handle or stand).

Last by not least, lets not forget the private investigator who cannot live without his Sherlock Holmes magnifying glass. It is imperative to his job and really a trademark of many a solved case.
