Topic
Modifying base curves
The correlation between
base curves and thick
lenses……what is it???
Some of us may associate high base curves with thick lenses.
It is for this reason that we prefer to stick to low base curves
when dispensing a high Rx. A fact some of us may neglect to
remember is that the primary cause for thicker than normal
lenses is actually the shape size measurements the A, B, DBL,
and ED, while the base curve only plays a minimal role.
Now, with the facts con?rmed, we will realize that the
excessive thickness on a high base curve lens is due to the
enlarged shape measurements and not the high base curve
itself. To help understand this better, produce a shape with an
eye size of 48mm in a 2 base curve. Now, remake the exact
shape with a base curve of 5. When ?nished, match them
together and you will notice that the 5 base curve lens looks
considerably smaller.
This may be something to consider the next
time you do a base curve modi?cation.

“Fall’s new releases incorporate a
lot of retro round shapes, color,
mixed materials, wood details and
pattern usage. A handful of new
frames (The Snapster, The Arnold
and The Wayne) feature a metal
checkerboard pattern placed over
a wood-textured insert on the outer
temples. It creates an earthy, slightly
Moroccan feel, but still looks clean.
Clubman and brow styles are also
big this season,” Rademacher said.
“Other frames, such as The
Anderson and The Jax, are offered in
blue shades, which is another fall
trend.”
The frame names are a hit with
consumers too.
“It is important for style names
to help tell the overall brand story
through a theme that is carried out
with each pair of glasses. Giving a
human name to a frame injects
personality in an object, making
it identifiable and relatable. “The”
before the name signifies there is
only one, and it is unique—just like
the Penguin consumer,” Rademacher
said.
Noting that the frames are made
of acetate, metal or a mixture of both,
Rademacher says the colours change
with the season’s trends.
“This fall’s palette incorporates
a few shades of blue, earth tones,
and tortoise shell is also back in a
big way,” Rademacher said, adding
the unisex appeal of the Original
Penguin line is an added feature for
retailers and consumers alike.
It’s hip to be square with geek
chic eyewear. •
