Frames Designs
Today we
have many different types of glasses to fit everyone’s
active lifestyles. Primarily we have casual eyewear,
dressy eyewear, sport s eyewear, computer eyewear and
specialty occupational eyewear. Facial shape and skin
tone analysis are used for selecting the proper shape
and color. Frame manufacturers can be broken into three
groups: Designer frames, such as Giorgio Armani.
Endorsement frames, such as Sophia Loren and Generic
frames. I think we need to explain the difference
between designer and endorsement frames. A designer
frame is usually made of the best materials and is
superbly engineered. An endorsement frame is usually no
better than a generic frame but is capitalizing off the
popularity of the celebrity. This has caused many people
to be skeptical about buying better quality frames.
A very good
rule of thumb we use in purchasing frames is to consider
the country where the frame was produced. Industrial
standards seem to be consistent with in a country. So,
if you think a country makes high quality automobiles,
then they likely make high quality frames. If the frame
is made in Yugoslavia and you like Yugoslavia quality
then the frame is okay for you. If the frame is made in
Japan and you like Japanese quality then this is the
frame for you. The differences in quality have to do
with whether the nose pads are made of silicon or
hard
plastic, whether the screws and hinge assembly are made
of zinc, chrome, or stainless steel. The frame itself is
made of high quality metals, such as titanium, how often
the electroplate is calibrated, polishing techniques,
and how the coloring is applied. Another important
aspect of frame quality for plastic frames is whether
the frame was injected molded, or lathed. If a frame is
injected molded, acids are added to the plastic so they
flow into the molds better. These acids cause the
plastic to fade and become brittle over time. Secondly,
the molds are flat. Therefore, the memory of the frame
is flat and not curved. This causes the frame to
constantly slide and for lenses to come loose. Lathed
cut frames on the other hand, retain their color,
adjustment, and hold the lenses better.
The shape
and size of the frame are also important in determining
the thickness of the lenses. For minimum thickness you
want to purchase a frame whose horizontal width matches
the distance between your two pupils and is round. This
is true regardless of what lens material you select.
