Pinhole Glasses

Pinhole glasses - like sunglasses with a ‘honeycomb’ grid of tiny holes - are a cheap and easy way to help improve poor vision. Many consider them helpful for people with mild-to-medium short-sightedness (myopia),* long-sightedness (hyperopia),* presbyopia,* astigmatism,* eyestrain or tired eyes, and people whose prescription glasses cause eye strain and aching.

Pinhole glasses may be used while doing everyday tasks. All the time you are wearing them you are improving your eyesight naturally. However, because they reduce your peripheral vision, pinhole glasses should not be worn when driving, operating machinery or carrying out any activity requiring sideways vision.

Wearing pinhole glasses helps your eyes re-learn to focus unaided by conventional corrective glasses. Many people are able to give up using conventional glasses altogether when they exercise regularly for only fifteen minutes a day. Many experts believe that pinhole glasses are much more effective than eye exercise techniques, such as ‘The Bates Method’. However, if you use both methods, the benefits will be even greater, and achieved more quickly. Copies of ‘Better Sight without Glasses’ by Harry Benjamin, which explains ‘The Bates Method’, can be bought cheaply on Amazon.

How pinhole glasses work
The retina is the screen of cells at the back of the eye onto which your brain tries to project the sharpest images of what you are seeing. If it focusses the images short of the retina,* you can only focus well on near objects (short-sightedness).* If it focusses the images beyond the retina,* you can only focus well on distant objects (long-sightedness).*

The ‘blur circle’
The greater the error in focussing, the larger the amount of blur around the image - technically referred to as the ‘blur circle’. The greater the blur circle, the more out of focus the image your eyes transmits to the brain. Conventional opticians recommend the use of corrective lenses (conventional glasses) which bring the image back onto the retina. This encourages the eye muscles to become lazy, which is why, once wearing conventional glasses, most people have to increase the strength of their glasses at regular intervals.
The ‘honeycomb grid’ of holes on your pinhole glasses reduces the effective aperture of your eyes (the holes in your eyes through which light passes) from that defined by the iris* to that of the pinhole. This has the effect of reducing the blur circle. The reduced blur circle makes it easier for the brain to recognise what to do in order to focus the image. Eventually, with practice, your brain re-learns how to focus at that distance. With regular practice, your brain and eyes work more efficiently together and their ability to focus your eyes becomes more flexible.

How to use pinhole glasses

Long-sighted people
Long-sighted people can see more ‘distant’ objects well, but have trouble focussing on near objects. You may improve your short/near sight by using pinhole glasses for close work, such as reading or computing.

Short-sighted people
Short-sighted people can see near objects well but have difficulty focussing on more distant objects. You may improve your long/‘distant’ vision by using pinhole glasses when you need to focus on ‘distant, objects, like watching TV or working or walking outside.

Computer operators
Because pinhole glasses make focussing easier, normal-sighted people may use them to reduce VDU-caused eyestrain. Pinhole glasses have been found to considerably reduce headaches and stress in people who do a lot of close work or spend prolonged periods in front of computer screens.

Exercising with pinhole glasses
Wear pinhole glasses for five minutes a day for the first few days, continuing to wear your normal glasses or contact lenses the rest of the time. Then build up to 15-20 minutes daily. As your eyes and brain get used to pinhole glasses you will find that the honeycomb grid seems to disappear and any initial multiple images diminish. At first you may experience aching of the eye muscles or headaches. Do not worry, this is quite common. Reduce the time you wear your pinhole glasses for a few days then build up your eye fitness programme more gradually. Eventually you can increase the time you spend wearing pinhole glasses to up to an hour or more, as comfort allows.

Why pinhole glasses rather than conventional glasses?
Most poor eyesight is caused by too much stress on, or ageing of, the eye muscles, leading to tiring and an inability to focus sufficiently. Using conventional glasses only increases the problem. Rather than re-strengthen and re-train the eye muscles they simply compensate for the muscles’ inability to focus. The result is a downward spiral of weaker and weaker eye muscles leading to the need for stronger and stronger conventional glasses.

Stress, heart-rate and headaches
Pinhole glasses may also help reduce stress, heart-rate and headaches.
Tests indicate that, when the eyes have to focus on a fixed point (e.g. a computer screen), for several minutes, the heart rate (one of the best indications of stress) can increase by around 5%. This is enough to cause tension in the shoulders and lead to headaches. Because the holes in pinhole glasses are smaller than the eye’s normal pupil size they relax the eye without losing the clarity of the image. The reduced stress in the eye is transmitted immediately to the heart and the rate of heart beat returns to normal within minutes.

PLEASE NOTE
1. How to adjust the fit of your pinhole glasses - You can adjust the bridge or the arms of your pinhole glasses for a perfect fit. Simply warm the part you want to adjust in hot water and bend to fit.

2. Important. Pinhole glasses should not be used to replace the services of an eye health specialist. There are many causes of poor vision other than weak eye muscles. If you are concerned about the health of your eyes please consult your eye specialist without delay.

 

These pinhole glasses come with a protective wallet and instructions on how to carry out additional eye exercises to strengthen the eye muscles and bring you better sight.
