Sometimes there are things that I need to read quickly, but I don't have my glasses on me. I am farsighted so, obviously, seeing without my glasses is not an option. I have tried using a small desk magnifying glass but am unable to see through that either. Is there anything I can do to help me read a newspaper article, or something else relatively short, when I don't have my glasses?
I found this Lifehacker article with a good answer.
Pinhole Reading Glasses
Put your index finger, middle finger, and thumb into a circle and leave a small hole in the middle (the three fingers of the same hand allow a tiny triangular opening which is held less than one inch from the eye). Bring the hole to your eye and look through.
How this works
By doing this you are limiting the amount of light going through the lens in your eye. This gives slight magnification and increases your range (depth of field) of clear vision.
