Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is claimed to be a clearer image
I hastily tried on my pinhole glasses as soon as they arrived. I am short sighted (-3 in both eyes) so objects faces and words which are any further than arms length away from me is just a blur!
It was a strange experience at first but once my eyes relaxed i was able to see the faces and read the words on the TV which is about 15 feet away from me on the wall. You are advised to use it for initially 15 minutes each day to give your eyes a chance to get used to wearing them. My initial reaction to them is that although great for looking at the T.V not so great to just wear around the house highly impractical to say the least as I cant see whats going on around close to me so I can only wear them while watching T.V , reading or blogging. I shall use them daily and note any improvements/worsening of my sight.
In the mean time here are some reviews on amazon from others who have tried pinhole glasses.
