Pinhole Glasses


Pinhole glasses reduce the width of the bundle of diverging rays  coming from each point on the viewed object. It is the bending of the outermost rays in that pencil of light which causes refractive errors such as myopia, hyperopia (farsightedness), presbyopia (diminished focusing range with age) and astigmatism.

Pinholes can bring about clearer vision in all these conditions.  The improvement in visual acuity can be striking.

The honeycomb effect of the holes is more noticeable when viewing a book held close to the eyes, because the eyes are focused just a short distance in front of the glasses. When looking at a distant TV, however, the holes are hardly visible at all since the eyes are focused much farther away. Also, because of the distance, you can view the entire TV screen through one hole, an obvious benefit.


Many people with cataracts see better through pinholes. Pinholes have been traditionally used for those with cataracts.  A cataract is one or more opacities in the lens that does not allow the light to pass through properly but instead cause it to scatter. Pinholes can reduce some of this scattering and improve vision.


One limitation of pinhole glasses is that blocking some of the light makes it more important than usual to have good lighting on the viewed object, even though the sharper image greatly compensates for the diminished light. When looking at television this is not a problem since the set makes its own light. When reading, a good lamp should be provided nearby. Another limitation is that peripheral vision is diminished, so they should not be used for driving or similar activities involving motion.

Can pinholes improve vision? With environmental causes of acquired myopia, pinholes may have a legitimate use in myopia prevention. When used for reading or other close work, pinholes reduce the amount of accommodation or focusing power that the eye must use to see clearly. There is an abundant amount of research that found excessive accommodation as the cause of acquired myopia. It is clear that anything that can reduce this accommodative effort, including pinhole glasses, is a useful weapon in retaining good vision.

Pinholes are best worn when watching TV or reading. When reading always make sure adequate lighting is supplied. As you look through Pinholes some light is cut out. Pinholes are also excellent for computer operators. Computer screens tire and strain eyes rapidly, Pinholes, allow your eyes to relax.Your eyes may take a little while to adjust to Pinholes, but in a short period your eyes will not notice that they focus through these tiny holes. That is why watching TV is ideal, you forget very quickly that you are wearing them.Pinholes should be worn for a few hours a day, or as often as possible.Never wear your Pinholes when driving or doing any activity where sideways vision is required. Do not use as sun glasses. Always make sure your Pinholes are clean and check no holes are blocked, it is very important to have complete vision.

Follow these simple exercises whenever you have a few minutes to spare.

STEP 1. Rotate your eyes from corner to corner in a clockwise direction, 10 times or more. Then repeat in an anti-clockwise direction. STEP 2. Move your eyes from side to side between the corners, 10 times or more. This action simulates Rapid Eye movement. STEP 3. Take a magazine or book. Hold it at arms length and choose one word. Concentrate on this word and slowly move your arms towards your eyes as closely as you can focus. Then slowly move to arms length again, still concentrating on your chosen word. Repeat 10 times or more.
