Pinhole Glasses: The Popular Alternative to Prescription Eyeglasses

More and more people are now becoming aware of the benefits offered by pinhole glasses. The indisputable fact that they improve visual acuity for sufferers of myopia, hyperopia, presbyopia, astigmatism and cataracts, coupled with their attractive style, durability and lightweight design make them an ideal replacement for eyeglasses in the home, office and for outdoor use.

They are suitable for people of all ages - from young children through to the elderly - and, unlike eyeglasses, pinhole glasses do not need to be changed whenever your eye prescription changes. One pair of pinhole glasses will quite literally last you a lifetime! You do not even have to have more than one pair for different tasks as the same pair of pinhole glasses are just as suitable for close-up work such as reading and computer work, as they are for middle and long distance activities, such as when watching the TV or admiring the landscape around you. Gone are the days when you need to worry about finding those 'reading glasses' that have mysteriously vanished off your sideboard, and gone are the times when you anxiously try and prevent your prescription eyeglass lenses from being scratched, marked or broken.

Pinhole glasses really are a hidden treasure with life-changing abilities - especially when you consider the mounting physical and scientific evidence suggesting that chronic use of normal prescription eyeglasses can actually accelerate the deterioration of your vision! - Read below to find out more!

The Hidden Truth about Eyeglasses

A ridiculous statement it may sound, but there is now solid physical and scientific evidence that prescription eyeglasses can actually do more harm to your eyes than good! In today's modern hi-tech world, where an increasing number of people stare at their computer monitors for hours on end, the ciliary muscles in our eyes have to work overtime. The muscles constantly flex the eye lens to make it thicker in order to focus the information on the computer screen as a clear image on the retina. Studies have shown that this constant close-up work actually accelerates the eye's natural tendency to elongate in myopes by increasing pressure in the vitreous chamber of the eye more quickly. The increased pressure pushes the retina further back so light rays focus in front of the retina, leaving a blurred image on the retina itself. This is known as acquired myopia.

Prescription eyeglasses use a corrective concave or 'minus' glass lens in front of the eye to diffract the light rays so they once again focus directly onto the retina. In fact, the lens makes the object in view appear closer than it is, causing the ciliary muscle to work even harder in order to focus, therefore accelerating the increase of pressure in the vitreous chamber!

Pinhole glasses on the other hand have the opposite effect, as the image through a pinhole has a greater depth of focus. When you wear pinhole glasses the ciliary muscle does not have to work as hard, and so the pressure build up in the vitreous chamber is slower. To find out more about acquired myopia, click here.
