Comparing the new Computer Conversion Clips, to several other
clip-on computer reading glasses offered on internet discount sites, have
resulted in findings that show significant optical and structural differences
among the clips. These differences can dramatically affect the computer user
both negatively and positively. You can learn to get more value for your dollar
with the following information. The clip-on computer reading glasses were
compared by design advantages such as size, shape, weight, and optical lens
quality to allow for the best computer user experience. It was an easy
comparison to make with the computer conversion clips design advantages
providing the best choice to reduce, eye fatigue, eyestrain and increased
physical comfort from neck and shoulder pain. What are clip-on computer reading
glasses?
A clip-on computer reading glass provides additional magnification
to be attached over the upper portion of the wearer's eyeglasses, converting
the distance prescription of general wear bifocals or progressive lenses to
mid-range computer distance; this will allow the wearer to see a computer
monitor clearly in the intermediate ranges between 18 to 30 inches more
comfortably. The wearer will then be able to view intermediate distances, such
as the computer screen, while maintaining a normal head position. This would
eliminate having to elevate the chin while moving closer to the computer screen
to see what is on the monitor more clearly while lifting the chin up to see
through the bifocal portion of their glasses. Ideally, the clip-on should only
cover the top part of the eyeglasses to allow the wearer to continue to use the
lower reading portion of their eyeglasses to see near.
Eye Care Professionals, and even Chiropractors, are the chief
means of providing these newly designed Computer Conversion Clips to the
public. You won't find the new clip-on's at the local internet discount sites.
The many design advantages of CCC's makes the small cost difference a bargain.
Eye care professionals and chiropractors alike understand and trust the digital
design advantages of the CCC's for their bifocal age patients who show signs of
eyestrain or neck problems while working at the computer with general wear
glasses for 2 or more hours a day. Computer users buy clip-on computer reading
glasses because of convenience and cost savings.
The general cost of a dedicated pair of computer glasses will
range from $175 - $350. The cost and quality of the eyeglass frames and lens
types used for a intermediate computer focus and near vision accounts for the
wide range in costs. Buying a computer reading type clip-on at your local
internet site to clip to your general wear glasses for about $20, sounds like a
great deal... until you learn about the design differences with the new
Computer Conversion Clips. It is good to remember that most of the neural input
that comes into our body is from our eyes, so vision is one sense that you
should value. Here are some of the valued differences in Computer Conversion
Clips verses the other clip-on computer reading glasses you can find on
discount internet sites.
Quality Lens Materials: All the usual brands of clip-on's sold on
the internet are made of a polycarbonate material. Polycarbonate is lightweight
and strong, but also scratches easier than most other plastics. Polycarbonate
material also tends to yellow with age and UV exposure. About 10% of the
eyewear population discovered seeing through polycarbonate material more
difficult than seeing through other lens materials.
CCC's are made of an acrylic material that is
more scratch resistant than polycarbonate, and acrylic transmits more light
through the lens medium than polycarbonate to the back of the eye. Motor cycle
shields are made from this material as well as windows on submarines. Digital
design optics with the acrylic material gives you high visual performance
across the entire area of the lenses.
Anti-fatigue Designed Optics: All the usual brands of clip-on's sold on
the internet have a very wide spacing for the optical centers of the clip-on
lens. This makes it harder for the eye muscles to maintain a comfortable focus
on the computer screen for long periods of time. The eyes are forced to
compensate for the wide optical centering by turning in, commonly called
converging, a greater amount than usual to maintain stereopsis and reduce the
possibility of any possible double vision.
CCC's are designed by eye professionals to
eliminate the extra work on your eye muscles that have to turn in or converge
in more than normal when viewing a computer monitor. This attention to
preferred optical centering, so the eye muscles don't overwork, helps to
minimize any unwanted eyestrain and eye muscle fatigue.
Non-glare Anti-reflection Coating: All the usual brands of clip-on's sold on
the internet usually don't apply a mulit-layered coating process to eliminate
glare and reflections on the lenses. This is a more costly process, and would
be reflected in the cost to the consumer.
CCC's come with a non-glare anti-reflection
coating to reduce headaches from excessive glare and reflection. The
anti-reflection coating improves vision with the resulting increase of light
transmission traveling through the lens to the back of the eye. All of us that
are bifocal age need more light, and this non-glare anti-reflection coating
will increase light to the back of the eye by another 8 to 10%!
Important Size, Shape and Weight Considerations: All the usual brands of clip-on's sold on
the internet are all larger in size and weight. A possible reason for this is
that these clips were designed when eyeglass sizes were larger some twenty
years ago.
