A few years later, I was laying on my back loving the warm summer sun. For some reason, I pulled my T-shirt up over my heard and what a surprise. Looking through the tiny holes that the weaving of the shirt created, I could see things perfectly. Yes, if you punch a tiny pin hole through a piece of heavy paper, you can see small things more clearly. Don't believe me? Try it. While looking through that pin hole, move the thing you are looking at closer or further away to find the correct focal length. Yep, it works.
I have heard that back in antiquity, that glasses with a single pinhole were used to see small things clearly. Today's modern pinhole glasses are quite different; they have many, many holes. Here is a picture of modern ones:
I had cataract operations, where they implanted new lenses. I chose to have long distance vision, so still have to wear reading glasses to read, blog on my computer, or see anything clearly at close range. My glasses work better than a hole in some paper, but the hole has come in handy at times when I forgot my reading glasses. Now, keep looking around and take in all that beauty that this world and this universe has given to us and have a great day, you hear?
I, too, can remember when I saw things clearly... the trees had individual leaves on them. Now it's funny, but the girl I thought was the prettiest in our class wasn't. Bill has cataract surgery tomorrow... that will make bird watching so much better for him (and probably girl watching as well ;-)
ReplyDeleteYes, he will be amazed. Since cataracts are a yellowish color, blue and yellow make green. So I could not see blues and yellows. Then after the surgery, I couldn't believe all the bright blue backgrounds in the news shows on TV.
DeleteIf I forget my reading glasses I make a small pin hole by bending my finger tightly and look through that. It's good enough to do the job.
ReplyDeleteBurning marsh mallows freak me out from the time I was a little kid and someone dropped one on my bare foot. Can't imagine how badly one in the eye would feel.
Yes, I do that, also. It sort of works like a microscope.
DeleteDizzy... isn't there something about looking from inside the Great Pyramid about that pinhole vision? Maybe seeing the moon during the height of daylight? Wish my memory was as good as my grasps of tidbits of life as I knew it. But I'll bet you know all about his...
ReplyDeleteI bet if we pasted together your tidbits with my tidbits we would get the true picture.
DeleteI had a pair of the new pin hole glasses years ago , they worked pretty good too.
ReplyDeleteI have never tried any. I thought that they would work, and thanks to you, now I know that they do.
DeleteI've been wearing glasses since my early teens. Now I wear trifocals and hate them. Squinting works for me to see things more clearly; have to try the pinhole.
ReplyDeleteI had my bifocals made special back when I was working on my desk-top computer every day. I had them made with a reading lens in the bottom, somewhere around a 22 inch focal length lens at the top of my glasses to see the computer screen and with a far distance lens that made up the rest of the glasses. Now, after my cataracts were removed, I only use reading glasses for close-up.
