Pinhole Glasses - What's The Secret

Just recently I received a parcel in the mail. Inside was a pair of glasses that looked very strange indeed. Upon further investigation, I realized that the lenses full of pinholes was not a 'fashion statement', rather they were designed with eye health in mind.

Soon after receiving the parcel, I re-read my emails to discover that the pinhole glasses were sent to me as a sample for me to try out and write an article giving my honest opinion of how they worked.

Although I personally have no problems with my eyesight, these pinhole eyeglasses are not just designed for people with refractive eye disorders or the elderly, but also for people who use computers regularly. I tried them while attending an online conference call late one evening, to discover that after the call instead of having the regular frownline embedded on my face and the beginnings of a migraine headache, I felt quite relaxed... I then continued to wear the glasses while watching a movie on television.

To say I was amazed is an understatement - at first, I thought there would be no way to get used to looking through such a device, but after no time I almost forgot I was wearing these glasses. I would not even try to pretend that I understand how the technology works (which by all accounts has been around for thousands of years) - but my readers can learn for themselves by reading here.

The secret behind pinhole glasses, is apparently that by reducing the number of angles from which light rays can enter the eye, only direct light rays within a narrow angular path can strike the cornea. This results in visual images with increased clarity, definition and brightness.

I often like to watch videos of Professor Robert Krampf (his 'experiments of the week'), and I recall one about using a pinhole in a leaf if you lose your glasses on a deserted island - perhaps the technology is one and the same?
