Can Reading Glasses Replace Botox?
Are you one of those people who went kicking and screaming into your
40’s? You know, the years when everything seems to change, especially
your vision. What happened?, your eyes were stable, all was good and
then one morning, bam! Presbyopia hits you, right in the eyes. It’s
true, if you are over 40; reading glasses
are just about par for the course.
The good news is, just because you are now confined to wearing readers
it does not mean you have to look like Mrs. Claus (or Santa, for that
matter.) Choosing a style of frames can easily change and even
transform your entire look. You can look fun, stylish, and cutting edge
all at the same time. And can you guess what that means? You’ll look
younger!
So now you can Don those trendy, bright little glasses. Pay attention,
you will notice people look at you a little differently. They are sure
to notice your youthful appearance. If you like, you can even get some
slick little frames encrusted with Swarovski crystals. And let’s face
it; you can’t go wrong with Swarovski crystals. I mean, come on!
Swarovski!
You will notice your friends are so taken by your trendy eyeglasses that the things you agonize over in the mirror will take a back seat. Lines? Wrinkles? Hah! Forget about them.
Could we be on to something here? Can reading glasses be the next botox? Is it possible that reading glasses
could take the “plastic� out of surgery and put it on a stylish
frame? Will the fountain of youth be flowing with streams of reading
glasses? Next time you find yourself straining to read the fine print,
just think “I could put my eyes at ease and look better with a pair
of designer reading glasses.

Computer Glasses for Computer Vision Syndrome Sufferers
The majority of people who suffer from the symptoms of Computer Vision
Syndrome (CVS) - blurred vision, eyestrain and burning - are
middle-aged and presbyopic. Presbiopia is the inability to focus at all
distances with symptoms including squinting and headaches. So, getting
computer glasses can transform the office environment for millions of
workers at their workstations. As the glasses correct the intermediate
zone of your vision, which is the typical distance (20-24") from your
eye to the computer monitor screen, they enable the eye muscles to move
from keyboard to monitor and back more easily. This alleviates the CVS
symptoms of blurred vision and eyestrain. Perhaps you are sceptical of
the need for specific computer glasses and consider them an unnecessary
expense: less emphasis has traditionally been placed on
computer-induced vision problems than on the ergonomic layout of the
workstation. Buying a pair of inexpensive, single-vision (intermediate)
lenses off the rack might, then, seem a good idea. Unfortunately, as
most people who need computer glasses also need their vision corrected
in the near, and maybe far, zones as well, ready to wear, single-vision
glasses don't usually fit the bill. Nor do cheaper, tinted glasses help
presbyopic individuals. The pupil dilation, which results from reduced
light entering the eye, can exacerbate the problem of blurred vision
and eyestrain. Let's move now from the cheapest, ready to wear,
computer glasses to affordable, but more expensive, eyewear with a
greater degree of customization. Lenses can be selected to match the
requirements of each eye. This gives you a pair of bifocal reading glasses
with the upper area optimized for reading text on your monitor, and the
bifocal area set to allow the correct focal distance for the keyboard
and desktop. Customization of the individual eyeglass lenses,
however, is sometimes not enough to prevent 'prism' which occurs when
your eye movements are not perfectly synchronised. To overcome this
problem, a choice of nose bridges is often made available which
realigns the distance between pupils and removes this particular cause
of eyestrain. These "do-it-yourself" computer glasses, which require
you to find out your existing "add" prescription for each eye, are
stylish and lightweight. They also come with anti-reflective coatings.
Not only do these reduce the glare from ambient lighting in the
workplace, which adversely affects the eye's ability to focus clearly
on the monitor, but they also increase the scratch resistance of the
lens. The best possible solution, of course, is computer glasses made
to match the requirements of your exact prescription and workplace
setup. Fulfilling these requirements means a visit to your eye doctor
and a willingness to pay more for your eyewear. Seeking professional
help represents, for most people, the safest option. The more popular
styles are the multifocals, particularly the progressive (no-line)
lenses. These have a larger intermediate zone than normal progressives
and allow you to see clearly in all zones (near, intermediate and far)
at the same time while at work. However, in occupational progressive
lens and lined trifocals, there is a trade-off between a larger
intermediate zone and distance viewing. Both will allow you to see
adequately in an office environment, but they are not suitable for wear
outside the office. This problem of one pair of glasses for normal use
and a dedicated pair for computer use, can be obviated by the use of
clip-ons. Provided you are fortunate enough to need two prescriptions
only in your lenses (intermediate and near or intermediate and far).
You can wear your regular prescription lens in the glasses and the
computer lens in the clip. Finally, there is a question of tinted
lenses in computer glasses. Opinions seem to vary on their use in
reducing excessive "blue light" spectrum. As we have seen, an
ultraviolet coating can filter out much of the blue light which reaches
the eye from harsh fluorescent lighting. The jury seems to be out,
though, when it comes to amber-tinted computer glasses. Many sportsmen
use them to cut down glare from a bright sun, but, in the workplace,
their use is not always thought to be beneficial. Some people believe
the resulting cut in light transmission and the concomitant increase in
use of the eyes focusing muscles, can aggrevate the very condition -
eyestrain - which the tint is supposed to alleviate. Choose your
computer glasses wisely, but if your blurred vision continues, look at
your work habits and evaluate whether your working environment is
ergonomically sound.

Wearing Eye glasses for low vision?
Eye glasses
for macular degeneration are one of the most common and effective
solutions for people with macular degeneration and associated vision
problems. Central vision, which is vital for ordinary everyday
activities such as reading, working at the computer and driving, is
what is primarily affected by macular degeneration. Although there is
no cure for macular degeneration, those suffering from the vision
problems caused by this condition can maximize the vision that they
still have with low vision devices such as special magnifiers and other
high-tech low vision aids; telescopic glasses and eye glasses for
macular degeneration is only one of the many options available.
To clarify how these low-vision aids work, it’s helpful to understand what age-related macular degeneration is and how it causes vision problems. The macula is located in the central part of the retina. Over time, macular cells start to die off or deteriorate, or else there is excessive blood vessel growth which causes bleeding underneath the macula. The result is damage to this part of the eye, which is what allows us to see fine details close up. Although peripheral vision is usually unaffected, activities that require attention to detail – such as crafts, driving and reading – become nearly impossible without the use of low vision devices.
Telescopic glasses are one solution for those suffering vision problems because of age-related macular degeneration. These special magnifiers consist of minature binoculars that are mounted either in front or above eye glasses for macular degeration. As far as low vision aids go, telescopic glasses are fairly low-tech, but are often the most effective solution for those with vision problems due to macular degeneration. These particular eye glasses for macular degeneration are also known as “bioptic glasses.”
Of course, there are several other low vision devices in addition to eye glasses for macular degeneration. Some of these are low vision aids that were the stuff of science fiction only forty years ago; others make new uses of old technology such as the television camera.
Considering that television is blamed for the decline in literacy in America, it is ironic that one of the most effective magnifiers for those with macular-degeneration vision problems who want to be able to read again consists of a closed-circuit TV camera and a monitor screen. The camera projects the image of the printed page up on the screen, enabling the patient to see it more clearly.
If the patient’s condition is beyond what eye glasses for macular degeneration can do, there is now software that actually allows the user to speak to his/her computer by using a microphone; the computer actually transforms this speech into actual text. There are also Braille printers available for PCs and Macintosh computers. However, if the condition is caught early enough, eye glasses for macular degeneration may be the best solution for most patients.
