Lens technology is currently progressing (pun intended) at a rapid rate. New lenses and technology are commonplace in the industry - but not always known to the consumer. It’s funny, when I ask a patient how they’ve enjoyed their lenses and if they’d like to learn about new options they’re usually confused. When I mention how many different varieties of lenses there are they typically answer “Don’t I wear a Zeiss lens?”

It is my honor and pleasure to publish in today’s Opticians Handbook eblast the first of what I hope will be many more research papers submitted by students or their instructors of vision science in the Darryl Meister Educational Forum section.

The eye is a complex piece of anatomy capable of determining everything from broad shapes to precise details. Among the many tasks the eye is able to perform, one of the eye’s key tasks is to aid in the determination of the many variations of color.

My personal career in the retail optical industry has spanned more than 40 years. I have seen amazing changes. When I started my training in Germany in 1973, we used glass lenses exclusively. CR39 was just coming on the market, and they were only used for safety reasons in children’s glasses. The optical quality of plastic lenses was clearly substandard, in our opinion, at that time.

In Befuddled by Blue, Part One, we learned that blue light filters that can be used indoors don’t provide a significant reduction in the blue light that disrupts normal sleep patterns. We also learned that the science is not yet available to allow us to conclude that the small dose of blue light emitted from digital device screens is a significant risk to eye health. Yet, we believe that recommending lenses that can be used indoors to reduce high energy wavelengths is a good precautionary measure, as long as the patient is educated on the greatest threat for high energy light damage to the eye, the sun.

Vision Expo is right around the corner. Hopefully you’ve already made your travel plans. Next on the agenda is your strategy. What do you want to accomplish while you’re there? From courses to the exhibit hall, events to parties, and let’s not forget the night life, a few days in Vegas may feel like a whirlwind. Take full advantage of the many opportunities by planning ahead: register for classes, note which companies you want to see, and schedule appointments when possible.

Blue light is in the spotlight. You’ve heard the claims…it emits from our digital device screens and is harming our eyes, disrupting our sleep patterns, leading to increased risk of: diabetes, obesity, cancer and behavior disorders. We are alarmed. Consumers are alarmed. We should provide good counsel on the hazards and recommend products that will help, but first let’s shed light (pun intended) on a few of the dizzying array of industry implied and stated claims that have us befuddled.

Size and Coverage (8) are inter-related. Look at this cyclist’s glasses, and then look again at the image of the young woman at the beginning of the course. Size and coverage is a key factor in comfort and they are different. Comfort therefore has more than one meaning and coverage describes how the frame and lenses deliver protection (glare and UV) while they make the long, wearing times outdoors, a pleasure.

Molecules in a polarizing filter are long in one direction (horizontal) and short in the perpendicular direction (vertical). Electrons can freely oscillate along the length of the molecule, absorbing or reflecting the light energy, while they are unable to oscillate very far along the short direction.

Your patients are seeking crisp, clear vision – the best achievable vision. The little-understood truth is that the greatest possible vision is dependent upon the confluence of many elements. It begins with a carefully produced refraction followed by the choice of a frame that properly holds the lenses consistently in the exact right position.

What makes for comfortable prescription sunglasses? Close your eyes and think of a variety of answers before you read any further. OK, got ‘em? Then ask your ECP colleagues what makes for a comfortable sunglass, I bet you hear a variety of answers. Are they the same ones you thought of?

It was suggested recently that I discuss the topic of “compensated lens powers.” With the growth of freeform technology pioneered by Zeiss, this issue has received increased attention. I have come to realize there is confusion over the fundamentals of compensated Rx’s. I will attempt to explain this in simple terms and avoid mathematical explanations.

In a recent ANSI Z80.1 meeting, we discussed topics for future consideration in the 2020 revision. One area discussed was how to best detect and categorize unwanted aberrations or localized power errors in a lens.

The spectacle lenses and lens treatments sector of practices are showing strength, findings from Jobson Optical Research’s 2016 Premium Lenses MarketPulse suggest. Compared to three years ago, 65 percent of retailers said that spectacle lenses and treatments made up a larger percentage of their location’s total gross dollar sales in 2015. In 2015, 53 percent said pricing on spectacle lenses and treatments has increased compared to three years ago as well, and 46 percent said that Rx sun lenses as a percentage of total dollar sales increased over the same period.
