When and How to Choose an
Alternate Progressive Lens Design

Just when we thought that we, as a profession, have maximized providing unique visual experiences for our patients, new innovations become available. In the past, we were limited
to what we could offer for visual solutions, especially in progressive lenses, regarding distance, intermediate, and near zones, and in fields of view. We have broken out of the mold. Meaning, that our lens design options are not limited to a front surface, predetermined design, which cannot be altered for the wearer’s wants and needs. For example, we can choose a design that maximizes the distance, intermediate, or near portions of the lenses.

Distance Vision Enhanced:

Professional drivers, and those who spend most of their time
outdoors will benefit from a lens design that maximizes the distance zone. Unless their
outdoor work includes building and construction, maximizing the intermediate zone would
benefit them as well.

Intermediate Vision Enhanced:

Those who need a wider intermediate area, particularly for
indoor use will enjoy a design that maximizes this zone. Examples: places like small offices,
working from home, even opticianry and optometry! When you think about our daily visual
tasks, much of it is in the intermediate range.

Near Vision Enhanced:

Avid readers, crafters, people who perform assembly work and
those who spend the majority of their day on near vision tasks will benefit from lenses that
emphasize the near zone. Many presbyopic patients wear progressive lenses only for near
vision tasks.

Additionally, we can offer design for all kinds of vocational and a vocational wants and needs…more than ever before!

Here are some options we can offer:

Driving:

Many people present with a chief complaint to their eye doctor of difficulty driving at night due to night myopia. The simplest explanation of night myopia is that uncorrected myopia (or deliberate under-correction of myopia produced by maximum-plus refractions, is less noticeable during the day, as there is more ambient light entering the eye. At night, especially while driving, there is less light entering the eye which causes the pupil to dilate. This uncovers undetected manifested myopia. Also, when the pupil dilates, spherical aberration occurs which stimulates accommodation. Adding minus power above the fitting cross helps a great deal. Endless Drive lenses add -0.25 D above the fitting cross, which helps to alleviate these symptoms.

Near to intermediate environment lenses:

This is not the same as maximizing the intermediate zone. A near
to intermediate environment lens is great for indoor office and computer use, gaming, cooking, playing cards, wood-working and more. We can even discover the patient’s working distances and customize the optics for the best focal length range. Please note: this design does not yield an adequate distance zone. It is not intended for driving or outdoor use.

Sports:

Outdoor sports enthusiasts, especially cyclists will enjoy this design. It provides a vast
intermediate to distance area, with just enough near when needed. Those who invest in these types of activities spend a lot of money on their bicycles and gear and adding eyewear that enhances their visual performance and safety is a no-brainer. Asking lifestyle questions may uncover a specific want or need. Lifestyle questionnaires are helpful, as are open-ended questions like: ‘How do you use your eyes, at work, and at play?

i-Rest:

There is no doubt that our society uses electronic devices more than ever, particularly smartphones and tablets. An i-Rest design provides a small amount of plus power at the near zone, which relaxes accommodation. This option is great for young,
pre-presbyopes and greatly reduces asthenopia, tired or
uncomfortable vision.

Future X Lenses TRIOX

High impact resistance

Not only is Triox strong and lightweight, it also offers 100 percent protection from UVA and UVB rays, sharper central vision, and sharper peripheral vision. Triox was developed for military applications, so it is good for outdoor use. Other benefits include resistance to chemicals and better light refraction.
Triox lenses benefits :

• High impact resistance.

This particular feature promises safety and minimizes the risk of injury among those who have active lifestyles.

• Lightweight comfort.

Triox has a lower density ratio than other standard plastics, making this substance one of the lighter materials used for lenses.

• Thinness.

With aspheric and atoric lens designs (flatter lens curves), Triox enhances comfort because it has a slimmer profile.

• Scratch protection.

Those who want to avoid scratches on their eyewear can ask for an anti-scratch coating on this type of plastic material.

• Optical clarity.

Triox has a high Abbe value that offers clean, sharp vision. This can be more important for those whose prescription powers are stronger but who don’t want to sacrifice visual clarity.

• Wider, more natural vision.

Aspheric and atoric lens designs reduce unwanted magnification and minification (objects appear smaller) found in more traditional eyewear. These types of design also increase the peripheral view by getting rid of distortion.

• UV protection.

Lenses made from Trivex provide 100% UV protection from both UV-A and UV-B radiation.

• No internal stress.

Unlike most polycarbonate lenses, Triox lenses are internally stress-free. This means that such lenses have a lower chance of breaking when under pressure, like from thick frames.

• Shape retention.

Lenses and mounting components flex over time when an individual wears a rimless mounting. This can lead to loose lenses and the need for replacements. However, because Trivex material is durable and strong, the shape does not change.

• Chemical resistance.

FUTURE X LENSES

POSITION OF WEAR

Most of us have not used these measurements because until recently, no single vision or progressive lens would allow for their inclusion in the design process. With the advent of digital surfacing technology manufacturing, real time lens design optimization that includes every aspect of how an individual’s lenses are positioned in front of their eyes is now possible. The resulting eyewear is as tailored to your patient’s visual needs and fitting tastes as a bespoke suit is to their body. All that is required is becoming comfortable with using not just one or two, but all the fitting parameters for every pair of eyewear you dispense.

WHAT IS POSITION OF WEAR?

In the past, we routinely tilted, bent and adjusted eyewear or sunwear to make them fit as comfortably as possible. Occasionally, clients prompted us to fit their frames in a specific way in order for them to see their best. But if you’re like me, you didn’t give much thought to the reasons behind why these individual client preferences for frame angle or position would impact their visual satisfaction. We simply complied with their requests and often hoped for the best. More often than not, fitting for the best vision was kind of a hit or miss situation—more pantoscopic tilt here or less face form angle there. With higher-power prescriptions we would be keen about comparing the fitted vertex distance with the refracted value on the Rx. And with progressives, we would follow the manufacturer’s advice and increase the angle of pantoscopic tilt and try to fit the new eyewear as close to the eye as possible
Today, we have a better way of ensuring the best vision is obtained from every Rx. Position of Wear (POW) is really a short hand term for describing how your client’s fitted eyewear has repositioned their lenses from those used to test their vision in the exam room.

TAKING POSITION OF WEAR MEASUREMENTS

Unlike a traditional order for single vision eyewear, measuring for POW SV lenses requires inclusion of pupil height for proper optimization, so it is a good idea to obtain POW values for every pair of eyewear you dispense. There are two ways to take position of wear measurements: manually and digitally. With either way, the most essential requirement is repeatability. This means that several sets of measurements taken for a single client by a single dispenser should yield found values within 0.5mm range. If not, practice until you can reliably produce values within this range. This applies to both the manual or digital methods. In all cases, the frame style selected must be fitted to the preferred position before these measurements are taken.

MANUAL METHOD

Since the dispenser is actively involved with tools and devices when taking POW values manually, we’ll call this the “hands-on” approach. (See chart above.)

PDs

Most lens designs require a visual axis measurement. But some may ask for a geometric pupil measurement. When using a ruler to obtain monocular visual axis measurements, a penlight or other light source must be employed to obtain the corneal reflex. Remember that a “digital” pupillometer is really a manual instrument with a digital readout of the value obtained.

Pupil Heights

When obtaining heights, maintaining appropriate and dispenser posture is challenging. I suggest a few measurements be taken and retaken to ensure proper fidelity.

Vertex Distance

A distometer, once used solely for cataract and other high-power fittings, is the tool of choice. Be aware that this measurement may need adjustment because of how lenses are bevel-positioned within a frame—especially for the higher-plus powers. The final thickness of plus lenses will impact your effective vertex value.

Pantoscopic Tilt

Do not confuse this with pantoscopic angle (which is the angle the temple makes with respect to the plane of frame front). There are several manual devices, such as the plumb scale from Carl Zeiss, which can be used for this measurement. The most important aspect of proper pantoscopic measurement is to be sure that the client’s facial plane (imagine a line from the brow to the chin) is as vertical as possible before the measurement is made. Although modifying a value because of client posture is appropriate when determining the fabricated progressive height, no allowance for client facial posture is to be made for pantoscopic tilt values.

Frame Wrap Angle

Also known as face form angle and panoramic angle, one can use a simple protractor or a dedicated frame wrap measuring device,
You can also obtain individual frame wrap values from the tables provided by some companies, such as Oakley and Luxottica. An important aspect of wrap fitting is eyelash clearance. When fitting a frame or sunglass with a thin Plano lens, remember that thicker Rx lenses may require increasing the vertex distance to obtain lash clearance.

DIGITAL METHOD

The dispenser is involved to ensure proper patient’s positioning when obtaining digital POW measurements. Most of these automatic devices employ an attached “frame guide,” which provides the cardinal points the digital camera requires to obtain its values. These frame guides are also important as they provide the needed information to help compensate when the client’s facial plane is not parallel to the camera plane. A full set of up to five POW values can be obtained with these newer systems, often with a precision of 0.1mm, a level rarely achievable with the manual method.

HOW DOES POSITION OF WEAR OPTIMIZE AN RX?

Position of wear is really a shorthand term for describing how your client’s fitted eyewear has repositioned their lenses from those used to test their vision in the exam room. The main benefit of position of wear Rx compensation is to deliver the best representation of the prescription as determined in the exam room. It’s easy to understand why when you take a quick look at the difference between the fitting values of the lenses used in an exam room versus how eyewear is routinely fitted:

Exam Room

Vertex Distance—typically averages 13 to 14mm.

Pantoscopic Tilt—Lenses of a phoroptor or trial frame are straight up and down, i.e., zero pantoscopic tilt.

Face Form Angle—Lenses are held in an absolutely flat plane, i.e., zero face form angle.

Pupillary Alignment—Particularly with phoroptors, they accommodate IPD in a binocular manner, and therefore cannot make allowances for monocular eye separation differences.

Pupillary Height—The patient’s eye is typically aligned with the geometric (optical) center of the phoroptor’s test lenses.

Fitted Eyewear

Vertex Distance—Fitted values can range from as close as 8mm to as far as 20mm.

Pantoscopic Tilt—Fitted values range from 0 to 15mm; typically 6 to 8mm.

Face Form Angle—Also known as frame wrap angle, fitted values range from 0 to 10 degrees. Wraparound sunglasses can range from 12 to as much as 25 degrees.

Pupillary Alignment—If measured ideally, individual (monocular) values are taken. Differences between the eyes may range up to 4mm.

Pupillary Height—Fitted values often find the pupil placed in most lens shapes between 3 and 7mm above the geometric (and in some cases, the optical) center of the lenses.

Position of wear compensation takes these differences into account. In determining the tilt and centration errors induced by these fitting differences, the lens optimization program will deliver a recalculated prescription that compensates for this. The prescription values created are referred to as the compensated Rx, and a work slip is created to facilitate verification by both the fabricating laboratory and the eyecare professional. In some cases, it may be desirable to tender the record of compensated values to the patient or the patient’s record, in order to prevent potential confusion in the future. An additional benefit for the lens optimization program in knowing all the actual fitting values is that the lens’ surface can be optimized in a global manner, and not just at one or two reference points on the lens surface. The result is a much more sophisticated representation of the original prescription, and elevates lens performance to levels not achievable through traditional surfacing or casting methods.

OPTIMIZING SINGLE VISION LENSES AND PROGRESSIVE LENSES

Do single vision lenses benefit from position of wear compensation? You bet! Stronger prescriptions, those with moderate to greater cylinder power and fitting situations where the client’s pupil is significantly above the mechanical center all greatly benefit from POW optimization. Where progressive lenses optimization differs from SV is in the reading zone. The eye’s depressed reading position represents another situation where the exam room findings may depart from the in situ fitting of the eyewear. At the typical reading level of a progressive, the values for both vertex distance and lens tilt become different compared to how the near Rx is determined during refraction. This is one reason why traditional progressive designs have recommended close vertex fitting and increased pantoscopic angle.

What can be done to optimize the performance of a traditional progressive? Not much. All we can do is gain an understanding and comply with the manufacturer’s fitting recommendations. The problem with this approach is that it leaves client preferences for fit and appearance as secondary to a lens’ designer’s fitting assumptions. Not the best place for a paying customer to be, in my humble opinion.

A BLUEPRINT FOR SUCCESS

Helping to optimize your patient’s lenses, differentiating yourself from the competition and becoming more aware of the importance of taking good measurements are all tangible benefits of getting to know about position of wear. Practices that embrace the value of POW measurements clearly desire to keep their offices at the very top of their game. Today, with the growth of online eyewear flooding the optical landscape, it’s always good to know where the high ground lies.
