This month, we’re going to take a little blast to the past. In my previous blue blocker articles, I’ve discussed the variety of lens treatments available for day-to-day wear, in order to enhance patient vision, diminish stress, and reduce the likelihood of potential illnesses and disorders later in life, such as AMD. What I haven’t discussed is blue light protective lenses for outdoors.

Selling plano sunwear poses a set of challenges. You must educate patients on why they should buy plano sunwear--and why they should buy it from you. The best approach is a team effort.

Do you agree with the statement, "Free-form, i.e., digitally-compensated lenses produce more satisfied patients"? I know most do agree, because when I ask that question to those in attendance at my classes, almost all of them selling digital lenses say they agree.

For every power, there is an ideal base curve. The industry, for various reasons, doesn't strictly adhere to this principle, but it's crucial to note that base curves are still very important. As it turns out, good optics are more closely related to base curve than typically thought.

It doesn’t look like a big problem. The average contact lens blister pack is less than 2” by 1” by 1/4 “. Contact lens companies are quick to point out that with daily disposables, your profits will be up and the amount of plastic being produced may actually be down, due to patients not needing contact lens care kits.

I love manual lensometry. If a fire were to suddenly threaten my boutique, I would grab my favorite vintage specs that belonged to my great-great aunt and my manual lensometer and then I would run for my life.

I had the honor to be the facilitator for the development of an education program “Refraction for Opticians.” You cannot understand refraction without knowing basic optics. Re-visiting trigonometry brought back memories of a lot of challenging math-moments and the glorious, “I got it,” experience. Searching for new tools to teach standard topics brought us to Khan Academy.

This month I’m taking a look at Zeiss’ DuraVision BlueProtect. In the interest of full disclosure, I didn’t come into this series with an intimate familiarity of Zeiss products; my optometrist when I was in college used them in his office, but I didn’t learn that until years later, and, at the time, I wasn’t a very discerning consumer of lens products.

In one of my last articles, Diversifying Your Lens Portfolio, I explained a three-tier approach used in the everyday operation of a car dealership. The car dealership sees different types of customers every day and they recommend a good, better and best offering according to the type of customer.

This week I finally went over the edge in dismay about OTC (over-the counter) readers. Within one week I had seen both my veterinarian and the owner of an international travel agency wearing OTC readers in bad repair.

We all know that awful feeling. When your new car gets its first door ding. When your new armchair gains chocolate-y fingerprints. When your smartphone screen gets scratched on your pocket change. When those new ultra-hip boots get rain-stained.

When recommending a lens material for your customers, it can be helpful to think of the business philosophy, “Value for Money.” In short, “Value for Money” is the idea that for every dollar spent on a product or service, the purchaser gets a certain amount of value or use in return.

Frame choice also drives material choice. Usually the patient will select their frames first and then the lenses. This can present a problem with some lens materials. Consider the combination of a plus lens and a grooved semi-rimless frame.

To many spectacle wearers, lenses are simply two pieces of glass (OK, perhaps some patients have learned that most lenses today are in fact made from plastic materials) suspended in front of their eyes by some type of metal or plastic “holder”.

When compared to CR-39 monomer, lenses made with Trivex material are up to 15 to 20 percent thinner and always about a third lighter. An aspheric design will further reduce thickness and weight. While there are other higher index materials that can make lenses even thinner, lightness depends on final lens volume and its specific gravity.
