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.

Eye Yoga
I recently spoke to a friend of mine who had notoriously bad eyesight asking him if he still wore contact lenses. To my surprise he told me that he had corrected his eyesight by drinking herbal teas of billberry and eyebright daily, in conjunction with doing eye yoga exercises. He added that he eat healthily lots of living (raw) foods and meditated daily! I was fascinated with the mention of eye yoga as I had never heard mention of it before. Below are a few youtube videos with guided eye exercises. Worth a try I think. My eyes really felt as if they got a work out! Its weird when I looked all the way to the left and right whilst keeping my head straight I could really feel the muscles in my eyes working!! Take a look at these:
In this video the yogi Baba Ramdev talks about eye diseases and talks about which ayurvedic powders,eye yoga exercises and foods can help improve eyesight and eye health.
Orthokeratology for short sightedness

Orthokeratology also known as Ortho-K is a non-surgical process which reshapes the cornea of the eye using special rigid contact lenses to reduce refractive errors of shortsightedness. The lenses are worn at night and gradually reshape the cornea and the new corneal shape is retained during the day. This method of reshaping is said to reduce the light refracting power of the cornea and reduce or eliminate shortsightedness and astigmatism.
After lengthy optical examinations a precise and accurate measurement is taken of the eye detailing the curvature of the cornea and then custom made lenses are manufactured for you. You need to have several follow up appointments with your Ortho-K practitioner to monitor your progress. It is claimed that your shortsightedness up to -5.00 and mild astigmatism can be corrected by this moulding of your cornea. It is not a permanant fix for shortsightedness, once your corneas have been reshaped you will need to continue to wear the night lenses as a maintenance measure,or your eyes will return to their original shape and your vision will deteriorate.
However the idea that you can wear these reshaping lenses at night and be glasses or contact lens free with great vision all day the following day is quite fascinating!
