A Doubter's Experiments Triggered by Pinhole Glasses
When I first involving pinhole glasses, I was highly skeptical. I already knew about old, even prehistoric, uses of wooden or leather eye-coverings with small holes punched in them, or hats with multiple strips of leather hanging down in front to cover the warm. But I assumed these were sunglasses. I have big-time medical problems in my eyes: corneal dystrophy that has one layer of the cornea in one eye almost totally opaque and a less developed corneal dystrophy in the other eye, plus cataracts in both eyes. The doctors won't operate until it's time to remove both cataracts, just like a cornea is transplanted and a cataract is later removed, the cornea has to be replaced a second time. Since each cornea comes person who has the generosity to ask that his or her cornea be given to a different person after the donor's death, it's extremely thoughtless to waste a cornea.So I'm at the ready.Then I came across an article about pinhole eyeglasses. I was, to say the least, extremely doubtful that this could possibly make sense. But my vision is deteriorating so rapidly that when Time passes back in March, only three months after my last visit to the ophthalmologists, I expect to enjoy a new prescription. As I do all my work, just about all of my hobbies, and a wide range of my socializing on computer, and my major hobby is reading, I am increasingly inconvenienced (the word 'handicapped' seems now to get politically incorrect, so maybe I should say 'impeded') by this situation.The whole idea of seeing better through pinholes made no sense whatever to my vision. But anything that will let me continue my lifestyle is worth checking out.The first thing I found was that we now have numerous articles online about them. http://www.myopia.org/pinholes.htm seems as good as the following others.I first tried the suggested experiment of looking through my slightly open fist. I placed a brochure I had been reading at a distance sufficient to make it impossible to read with my glasses, although the headline was readable. Looking through my slightly opened fist, I found the headline quite clear and also the brochure itself readable and fairly clear. But that was using only one eye area. Either of my eyes, using glasses, is weaker than both eyes together using glasses.With my glasses off, the headline was slightly more readable than it was that's not a problem glasses, and the text was readable without glasses with some difficulty. But this was predictable. At 65, I have presbyopia with all its trimmings. Looking through both fists, I could not get the images from both eyes to merge as they do with eyeglasses; however, I could still see the text with greater clarity than I could with my glasses.For my next step, I took off my glasses and got a small flat strainer from the kitchen. Looking through it, I could start to see the print somewhat better than I could with my glasses and slightly better than I could without these people.I then brought the brochure closer to i. I could read the headline very easily, but could read the text with considerable difficulty. Without my glasses, reading through my not quite clenched fists, I could out there the text somewhat compared to I could with my glasses and slightly much better I could without my glasses. With my worst eye, I could barely read the print, but using my worst eye with or without my glasses I could not read the print at all. Without my glasses and with the kitchen strainer, I could see no better than without my glasses.
I then tested my better eye the same manner. Without my glasses I could look into the headlines easily but the link only with extreme complications. Through my almost-clenched fist, I could read the text easily. Using the strainer, I could see the text very little much better without the glasses.For my final experiment, I got out my Amazon Kindle ebook. I have it set for the largest type size, but throughout the last few months I come to be unable to read it without my glasses. Looking through my fist, kind was quite clear. Looking through the strainer, most likely was readable but blurry with the bad eye, readable with the good eye.The conclusions I discovered were as follows:(1) The wires of a kitchen strainer, such as you would use to strain tea or squeezed citrus, are set too close together.(2) Great hole made when you have unclenched your fist adequate to see through it can be the right size.This suggests that the prehistoric and protohistoric wooden or leather glasses with square holes carved in them would been employed by far better than anything different available to them in restoring failing visions. The gaucho hats with the leather fringe dangling before the eyes probably work well. However, I would not be willing to substitute either of items probably for my glasses nowadays. If it became impossible to get good glasses or plastic lenses, I would use wooden glasses with small, square holes. With these and no cataract and cornea surgery, I would eventually go blind, but with regular glasses and no cataract and cornea surgery I would eventually go blind anyway.I would advise that more study be done on this by eye doctors. Some people have asserted that use in the glasses quite early can retrain the eye observe properly. At my age and in my stage of visual health, Cannot try this. But I noticed a possibility that it may work, and in particular it might be compared to using an eyepatch to improve amblyopia. One thing pinhole glasses are NOT is superstition; another thing it isn't is pinhole, unless my visual reaction to little holes in the strainer is an artifact of my age and visual health.And if you read Jean Auel, remember how the sunglasses Jondolar made for Ayla's use as they crossed the glacier hold worked.
Mike has been writing and publishing articles about health products. He recently came across internet site on pinhole glasses which gave the information needed for this old technique of using pinhole glasses for eyesight static correction. Mike himself had tried the product and found it quite beneficial. Here's an article about pinhole glasses.
