We always want patients to leave our office with exactly what they need to achieve optimal vision and quality of life.

We are fortunate to have a spectacle lens that allows us to give this to our patients while greatly boosting our profitability. Those spectacle lenses are provided by HOYA and include Binocular Harmonization Technology (BHT), which ensures our patients are always seeing their best.

HOYA’s patented BHT recalculates and adjusts the progressive power distribution according to the actual used positions on each lens so that both eyes experience the same accommodation support.

Striving for–and Achieving–Excellence in Vision
Our goal for our patients is simple. We want them to see as good as possible; so-so vision is not the goal. HOYA delivers incredibly high-quality products that meet and exceed patient expectations, making achieving that goal for our patients easy.

We prescribe a variety of HOYA lenses. For single-vision we prefer their newest option, the MySVwith 360 ⁰ Visual Comfort™ . For progressives, I Prescribe the latest iD LifeStyle® 3 and iD MyStyle® 2 families of lenses, and for near-variable-focus, work/computer glasses we use the iD Space, iD Screen or iD Zoom. We prescribe all our lenses with anti-reflective treatments, and photochromics based on patient lifestyle. In addition, we recommend that all our patients who wear prescription glasses also wear prescription sunglasses.

BHT Makes the Difference Between Average & Great Lens
As optometrists and opticians know, most patients have different prescriptions in their left and right eyes. This can lead to image size variability between the eyes and prismatic effects which occur in non-primary gaze. BHT corrects and minimizes these differences. For patients, this means that they have easier adaptation to their glasses, see better and have reduced asthenopia.

I’ve never heard an optician say that they love troubleshooting lenses with a patient, or an optometrist say that they love an Rx check. BHT has resulted in our remake rate for non-adaptation to PALs being cut in approximately half. Lenses without BHT are more difficult to adapt to. BHT eliminates or significantly reduces the negative effects of this unintended, induced prism.

High-quality lenses with BHT result in increased 5-star online reviews, second pairs and referrals. This correlates with practice growth and profitability.

Creating Many Patients’ First Pair of Truly Great Glasses
Patients who have high anisometropia often have best vision achieved using contact lenses. There are many patients going forward who will now have glasses that are  not only wearable, but comfortable. In the past, patients have objected by saying that there is no point in getting glasses because they can’t see well out of them. It is so important for patients who wear contact lenses to have glasses. There are circumstances where, on occasion (for medical or other reasons), they can’t wear their contacts. We can now explain to them that these lenses will minimize the negative effects that they have experienced in the past. The BHT in HOYA’s lenses make this newfound happiness wearing glasses possible.

A Team Approach to Providing Superior Vision
Industry terms are lost on most patients. They don’t know what AR means, they don’t know what trivex or high-index is, and many don’t even know what the term “progressive” refers to. A team approach, starting with the doctor in the examination room and continuing with the optician, using simple language and analogies when applicable, works best.

For example, we might tell a patient that they are being prescribed thin, light, clear, glare and reflection-free lenses using the latest technology of design to make them see their best. I like the analogy of having one longer leg, and how shoes can be designed to compensate for this. “Our lenses are designed to minimize the effects of the difference between your two eyes. And just like you can make a shoe with a bigger heel for the shorter leg, so you don’t limp, our lenses do that for your eyes.” The patient is then told that this is called Binocular Harmonization Technology, which is exclusive to their HOYA lenses, and that it allows both their eyes to work together properly.

The patient learns the reason behind the excellence in quality we can provide them within their glasses, and remembers our practice as being the place that finally solved their vision challenges and transformed their quality of life. With products like HOYA lenses with premium technologies, it’s no wonder that our patients overwhelmingly return to us time and again for care–and to purchase multiple pairs of glasses!
