The purpose of viewing through the tiny hole is that it reduces the pin-points of light known as “circles of confusion”. A large hole allows numerous “circles” of light that contribute to dispersion/interference of the image that make it look fuzzy whereas a small hole allows fewer “circles” that bring more clarity by eliminating the fuzz factor of overlapping points of light.

When viewing an object, hold the card just in front of your eye, then bring the object for viewing up close until it comes into focus. You would be amazed at the detail that can be seen on a coin, postage stamp, wristwatch, your finger prints, or more practically, medicine bottle labels and instructions. When possible, view your object in good light. This also helps your iris to constrict, thus enabling better focus as well.

On one occasion I made a wallet pocket magnifier that consisted of a plastic credit card sized piece from a coffee can lid with a single hole punched through it. It came in handy when I needed to read a serial number off of a water heater in a closet. In the tight and somewhat dark quarters, I was able to read the number without a flashlight or reading glasses.

When you have a little spare time, make one for yourself and discover it’s amazing ability for yourself.

On a smaller scale, a drop of water can be used as a magnifier as well. A drop of water can be placed on a flat horizontal pane of glass that in turn can be held over a subject to be magnified. Drawing a small circle with an oily substance such as butter or grease will help contain the water drop. Alternately, you can take a piece of non-porous material like a piece of plastic or waxpaper and then using a hole punch make a small hole. By dipping your finger in some water you can transfer a water drop to the hole where it will become suspended, thus forming a lens. You can control the amount of water and thereby alter the magnification power.

As I pondered this mini-magnifier I realized that a possible application would be to use it in conjunction with my cell phone camera, both for close-up viewing and to photograph. I found a clear plastic bottle and cut out a piece. I took a hand-operated hole punch and made a hole. Then I dipped my finger in some water and transferred a drop into the hole where it was suspended. I decided that a small dime would be my subject (see photo).

Because water is liquid it will wiggle and potentially blur, especially when photographing. I found that low profile items like pens or pencils will help to brace the camera and plastic water drop holder when it’s held over the item being viewed. It is also helpful to have strong light from the side for illumination.

This “lens” may be thought of as a “life hack” rather than an emergency tool, but then, reading fine print on a map, a phone number in a directory or examination of a small cut or injury may be urgent and this may offer a solution in a pinch. Give it a try and let me know how it works for you and how you used it.

I happened to be visiting an industrial facility at the time and it was early evening with the sun lowering on the horizon. I grabbed a small amount of dry shredded bark mulch off of the landscaping and located two pairs of reading glasses. I spotted a friend who I asked to take pictures with my phone’s camera while I began to focus on the tinder. Although the wind was rather brisk, in short order smoke began to appear and with continued focus a large sized ember took shape. I set down the glasses and clutched the tinder and began to blow the ember into a flame. My friends cheered and we were delighted with the results.

Now that we have passed the Spring Solstice, experiments like this are performed much easier. Reading glasses are straight forward magnifiers whereas prescription glasses my not have the same capability due to various optical corrections. In any case, it would be wise to familiarize yourself with this solar fire method because you never know when it might be needed in an emergency.

Lip balm can also be used as a lubricant. It can be applied on areas of your body that are prone to chaffing to reduce friction. It can also be used on mechanical items like hinges or threads to facilitate fastening nuts onto bolts. It can also be used as a moisture barrier to prevent corrosion. Because of it’s oily/waxy nature it can be used to control water flow whether near your eyebrows to control sweat, under the lip of a pitcher to control drips, or on a tent line during a rain. It can be used as a sealer around seams or small orifices.

In a camping scenario it can be used to enhance tinder performance for starting fires. You can cut a thin pad of balm and press a magnetized needle through it enabling it to float on water for an emergency compass or you can tie the whole container onto a fishing line to use as a float. In a domestic scenario it can be used to write a message on a mirror, a pane of glass or a windshield. A friend told me that he uses it on the face of his gold clubs for better ball control.

I carry a medicated lip balm that contains clove. It helps to heal the cracks on my finger tips in Winter time. It helps to stop bleeding of small cuts and soothes abrasions. Because of it’s fragrance I’ve also used it as a deodorant in short term situations.

Whatever circumstances that you find yourself in, whether in emergency or for convenience, lip balm will most likely find a place for good use.

In my case, my wife taught me this trick when I couldn’t read the numbers on my old cell phone. I was truly amazed and now I’m eager to pass this trick on to all the newbies in the reading glasses crowd.

If you use reading glasses and haven’t tried this method yet, you need to give it a try… you too will find it amazing!
