Pinholes 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.
