Pinhole Glassses, can they improve your sight...

Do you work all day at a computer? I do and I worry about what it is doing to my eye sight!

Pinhole Glasses Direct recently contacted me and asked if I would like to take a look at the product. The concept behind these glasses has been interested me for a while so I thought I would take a look.

What are Pinhole Glasses and how do they work?

Pinhole glasses a standard shaped pair of glasses with opaque plastic lenses full of little pin holes. Wikipedia says that these glasses work in the following way:

“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 often a clearer image. Unlike conventional prescription glasses, pinhole glasses produce a clear image without the pincushion effect around the edges.”

These glasses interested me because they may actually strengthen my eyes and allow me to slightly reverse or stall my prescription. They are also claimed to increase depth of field and create no distortion of the image that you see (unlike regular convex lenses).

Wearing them for most tasks that do not require a large peripheral vision such as reading or using the computer is no problem and if you are not worried about what you look like you could use them at work too!. Personally I think I would only wear them at home! The Pin Hole Glasses Direct website has further information on how pin hole can be worn in place of prescription glasses and how they may benefit you.

Cons of Pinhole Glasses

The Pinhole Glasses Direct website provides some interesting reads to learn further about this product. In their article The Science behind Pinhole Glasses they talk about the use of pinholes in the past and mention such interesting things as the Eskimos adaptation of the technology.

They are well priced at only $19.99 a pair or $29.99 for two.
