Athletes depend on their gear to perform to
their personal best. For example, if you're a
cyclist, your performance is heavily influenced
by the bike maker and construction, sprocket
ratios, derailleur, shifters, seat and tube, wheels,
fork, pedals, shoes, jersey, arm warmers and others. Each part of the bike and the clothes you
wear contribute to your safety and performance.
For cyclists who wear prescription eyewear,
the right outdoor eyewear is as important as
the bike or cycling gear. Nonetheless, presby-opes had to compromise their vision, potentially limiting their sport performance by wearing regular, general purpose multifocals.
General purpose multifocals are designed for
common daily activities such as driving, walking and working at a desk. Athletes have different visual needs for their unique sport. Oakley
True Digital is the first progressive lens that
further differentiates into a suite of sport-specific progressive lenses to deliver optics
designed for cycling, golf and fishing.
INTRODUCING OAKLEY SPORT-SPECIFIC PROGRESSIVES
Developed as a personalized progressive lens
solution for cycling, golf and fishing, each new
Oakley lens is designed with the activities and
visual tasks the sport demands. Using Oakley
True Digital technology to create these three
designs, lenses can be optimized for the needs
of each specific sport. When combined with
complementary colors (sport-tuned filters),
coatings and protective properties, they provide a comprehensive sport solution for the
Sport-specific lenses are the sum of their component parts. They are made up of: 1. Optics:
A progressive lens that delivers optics required
for the way in which an athlete uses the lens. 2.
Color: Tints and filters that boost color contrast to enhance performance in each sport's
environment. 3. Coatings: Automatic back surface AR, which virtually eliminates the backside reflections that can hide important objects
and affect split-second decisions. They also
repel dust, water and oil for better visibility
while providing longer surface durability. 4.
Protection: Provides improved impact resistance and absorbs 100 percent UVA and UVB
radiation, and 5. Finishing: Ensuring a close and aesthetically appealing fit, which can
be enhanced by features like venting to
reduce the occurrence of fogging.
THE RIGHT SOLUTION
FOR ATHLETES AND
You may be wondering why I would suggest a lens tuned for the athlete when a
patient only sometimes plays golf or rides a
bike recreationally. My answer is always the
same. I can provide eyewear that is "adequate," i.e., does the job like a car that gets
you there but doesn't have leather, an iPod
dock, GPS or heated seats, or I can suggest
products that provide excellence in eyec-are, describe the benefits and let the
patient make the choice. Usually when
there's a clear set of benefits that defines
value, patients make better choices. Further, these patients tend to tell their friends
and family about my practice, and they
become loyal customers.
When talking to presbyopes and also
serious cyclists, I hear that cycling glasses
must be easy to use, provide vision as natural as the way a cyclist uses any of their
other equipment and must not add any
additional work for the rider. That's logical
since any rider, serious or recreational,
doesn't want to have to work to see clearly
especially when riding where traffic is
already present. Recommend sport-specific
designed lenses with the right colors and
coatings. They provide the best mix of protection and performance.
CYCLING: THE PROBLEM
I can talk personally since I'm a cyclist and
a progressive wearer. Riding a road bike
typically places my chin higher than when
walking or sitting when I ride leaning on
the tops of the handlebars. This position
is even more extreme "in the drops," with
hands on the lowest portion of the bullhorn handlebars. I certainly don't use the
lens like a general purpose lens while
walking around. That means lens utilization is completely different.
Fig. 1 defines a variety of specific areas
of use and a cyclist's bike position when
viewing through that point on the lens.
Above the lens midline, good distance
vision is required for a range of head/chin
up positions. At the midline and below, the
cyclist benefits from improved clarity.
CYCLING: THE SOLUTION
Oakley True Digital Road Cycling is designed
with the cyclist's riding positions that change
head/eye position and the approximate time
spent there. This allows the optician to deliver a lens with a large clear distance, long
intermediate, narrow near with increased
mid and far peripheral clarity.
Riding zone (distance and far periphery): A clear distance portion is needed from the
fitting cross to almost the top of the lens. A
clear periphery is necessary lower because
of the chin up riding position and awareness of riders or traffic near you, and for a
good road view.
Electronic zone (near/intermediate): Finally, that fast glance at the computer
requires a narrow near spot low in the lens.
This design also provides a long intermediate that helps to provide a softer periphery.
Lower Periphery: In road cycling, the rider
uses the entire lens to see who is pulling
out or breaking away from the peloton as
well as any traffic that may be of concern.
CYCLING: COLOR FILTERS
For all-day rides, it is not uncommon to be
riding in and out of the shadows, through
tight shady corners. As a result, dark gray is
too dark. Therefore, consider Oakley OO
Red Polarized as an example of a color
designed for the cyclist for all-day riding. It
is cycling-specific because as a dark red/
rose tone, it enhances contrast and is less
dark, transmitting about 18 percent light.
In the graph, note that both red and gray
absorb the blue wavelengths to reduce
scatter but then differ. The red transmits
green through red, which enhances contrast and increases average transmission. It
is not as dark as a dark gray so it works
well in the shadows. Other considerations
are the gray of the road, colors of cars or
other riders around you, polarized for
reflections off the asphalt riding early
morning or at dusk. AR is automatic on the
back. Add a mirror and the mirror will
darken the lenses about another 10 percent
for riding in brighter conditions.
GOLF: THE PROBLEM
As most presbyopic golfers will tell you,
the reading portion (addition) of their
glasses gets in the way while putting, and
the peripheral blur of a progressive or the
segment of a flat top obscures their vision
when addressing the ball at the tee. Either
the correct intermediate power is needed,
or the full power of the add is in the
wrong place. Also, from the tee or fairway,
sighting of the flag and the pin requires
clear vision while the eyes and head rotate
to look from ball to flag.
A golf lens (Fig. 3), requires clear vision
in a large enough distance zone vertically
and horizontally to see the flag while at the
tee. At the tee, the chin is down and the
ball needs to be seen clearly, yet about that
same distance is required when putting
with the same clear vision demand. During
head turn, the corresponding eye rotations
through the lens near the midline require
clearer vision to follow the ball when driving, with eyes and chin up. Finally, full add
power is needed for scoring and reading
the menu in the clubhouse.
GOLF: THE SOLUTION
Oakley True Digital Golf is designed with
a wider distance, while increasing the availability of the intermediate. The rate of
power change is stabilized for a longer
intermediate. The rate of change is slow,
ramping to only about half the add power,
about 13 mm below the fitting cross. This
is more consistent with golf's "far mid-range" requirement, i.e., seeing the ball
clearly while putting or at the tee, about
four to five feet away. It then finishes with a
small add for scoring or reading.
GOLF: COLOR FILTERS
For lens color to be golf-specific, consider
the surrounding environment. In the
environment of grass (green), sand (beige)
and sky (blue to gray), and the requirement
to follow a blue white ball, the contrast-enhancing colors of browns, purples and
roses have been preferred. In addition, to
increase depth of field, i.e., to ensure that
all the twists of contour on the greens can
be made visible, slightly more light transmission than a darkest gray ensures three
things. First, the flattening of colors that a
gray lens produces is changed for the
color enhancing tone of browns and roses.
Second, a smaller pupil provides increased
depth of field. Third, these colors absorb
the shorter blue wavelengths, which produce haze and scatter. The G30 Iridium
lens is about 15 percent transmission,
absorbs more blue, transmitting yellows
and reds for a brown-appearing color.
Polarized lenses? There seems to be personal preference here since polarization can
mask some of the shadows created by individual grass blades especially where different kinds of grasses are used based on local
growing requirements. Let patients choose
based on their own likes and dislikes.
FISHING: THE PROBLEM
Do fish get presbyopic? Fishermen/
women do. That means difficulty when
tying flies, seeing fish when wading and
casting placement, all when the lenses
worn might add blur where blur gets in the
way. Sunglasses for people boating and fishing are essential, so here's an opportunity
to personalize them for the way they fish.
If one were to create a presbyope's lens for
fishing, the tasks and the eye's position
would help define the design. In the upper
portion, for distance vision, a scan of the
horizon while traveling on the water and a high clear zone for head/eye movement
when casting are required. Below the fitting
cross, enough clear intermediate is needed
for the safe use of fishing gear or wading in a
stream. Finally, a large enough near zone
and the right add power is required for for
all the near tasks like baiting hooks quickly
FISHING: THE SOLUTION
Oakley True Digital Fishing is optimized for
a wide distance for a broad area of visibility
and a large near for baiting while balancing
the design to provide enough intermediate
and overall clarity for boating tasks. By
extending the length of the intermediate,
peripheral clarity can be enhanced while
controlling usefulness of the near.
FISHING: COLOR FILTERS
Lenses must be polarized for water activities since reflections off shiny water surfaces become polarized and obscure vision.
Reflections also increase ambient brightness so being on the water is brighter than
with just the sun shining down. To reduce
reflections and eliminate blinding glare to
be able to see below the water surface,
always use highly efficient polarizing lenses. Very light tints that are also labeled
polarized typically have little polarizing
efficiency. Choose the best lens color since
they are different for each patient's type of
fishing. Streams and flats require high
contrast browns and ambers. These colors
filter blue wavelengths and as a result,
improve contrast and highlight details
below the surface. Browns and ambers
work well in overcast conditions but in full
sunlight, your fisherman may prefer a
darker gray lens.
Consider the variety of fishing conditions:
early morning surf fishing in overcast conditions, the middle part of the day when a
full sun is overhead or at dusk when details
are masked by fading light. A variety of
lens colors in a frame with interchangeable
lenses are in order. In fact, many fishermen
I spoke with had more than one lens color
sunglass and used them for various conditions. For daytime deep-water fishing, the
sun can be intense when reflecting off the
water, especially when fishing outside all
day. A dark gray, polarized and mirrored
lens is recommended here. The right sun
lens color improves comfort so the angler
can concentrate on fishing rather than
discomfort or glare.
For the next patient, ask: "What do you
wear for outdoor eyewear?" The silence
will cause patients to think about it and a
simple answer from them of "sunglasses"
allows you to then ask, "Do you like them?
What could they do better? What do you
use them for outdoors?" Using these questions lets us understand how we can open
the discussion for personalized and sport-specific progressives. A direct question
asking, "Are you a cyclist (golfer, fishing
enthusiast)?" gets to the heart of it sooner.
FITTING AND DISPENSING
Fit a sport-specific lens like any other progressive, i.e., dot the pupil center and then
verify the lens when the glasses are
returned from the Oakley lab. The fitting
cross is located at the pupil center. The lens
has been designed for its optics to be fit at
the pupil center. When dispensing,
describe to your patient that the variety of
clear zones have been tuned for their sport
vision requirements. Verify distance prescription using the reconstructed power
(this will be on the job ticket returned with
the job from the lab). Verify the add power
by the engraving.
Looking for a better way to add that elusive second pair? Stop thinking of them as
seconds. Find your cyclists, golfers and
fishermen/women, and they'll thank you.
Tell them about the new Oakley True
Digital sport-specific progressives, and
how they will become part of their essential
gear for the best in sport vision.
