Reading Glasses x 2 https://survivaltek.com/?p=2743 https://survivaltek.com/?p=2743#comments Sat, 28 Apr 2012 02:59:49 +0000 https://survivaltek.com/?p=2743 Imagine that you’re traveling on the road at night with no GPS to guide you. Nothing looks familiar but fortunately you have a map of the region. The only problem is that the overhead light is marginal and you’re over 40 now and the fine print is only a blur. Your spouse offers their reading glasses that you put on with resignation. However, that small type still eludes you. You remember that you keep a spare set of reading glasses in the glove compartment so you take them out to see if they work any better, but they seem to be the same level of magnification. All of a sudden a brain storm strikes… what would happen if you combined the two glasses and wear both of them at the same time? Voilà ! The fuzziness becomes clear enough to read and you are able to find your present location and the means to reach your destination.

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!

When we think of pirates, images of eye-patches come to mind. On an episode of Mythbusters, the team tested the hypothesis that pirates kept one eye covered so that it would remain sensitive in the dark, so that when they raided ships, they would uncover their patched eye below decks and have better vision in the dark. This proved to be true. It can take 10 to 20 minutes for your eyes to acclimate to the dark. It takes a moment of bright light to “blind” you until you can return to the dark and recover. In an emergency situation you may not have the needed time to recover your night vision.

A friend recently wrote to me about this principle that was taught to him by his grandfather. If you have been outside in the dark and need to go indoors briefly for some reason such as to answer a phone or fetch a tool, you can close one eye before entering the building and keep it close for the duration of your time inside. Once you exit, you can open your closed eye and it will retain it’s sensitivity in the dark. This technique could prove critical if you don’t have supplementary lighting like a flashlight.

Take time to practice this technique. Once you make the quick trip inside a lit area and then return to the dark, compare the vision from each eye and notice the difference.
