Joining me today are Dr. Michelle Hoff, Associate Clinical Professor at the Berkeley School of Optometry and Dr. Isabel Kazemi, Assistant Clinical Professor at the Berkeley School of Optometry.

They’re here to share highlights from their talk, “Demystifying Near-Task Specific Lenses,” which they’re presenting at this year’s Vision Expo West in Las Vegas. Could you both share with us the main takeaways from this presentation?


The main takeaway is that people today are very different from people even 20 years ago in the way we use our eyes. And our presbyopic population needs task-specific eyewear because we constantly use, as we do today, our digital devices for work, play, shopping, and more.

Thus, our presentation discusses the visual solutions you can offer your patients and the theories behind them.


That’s right, Isabella. And speaking of technology, you know, lens technology has advanced with the technology of the devices that we use. And so, to keep up, we have so many different lens designs, and we’ve found that it’s important to analyze and understand those lens designs.

So we are going to share how we analyzed and evaluated these lenses and then how to prescribe them as there are different lenses for different tasks.

We now have task-specific or prioritized goals that can help us with all the different things we do. For example, there are general wear progressive glasses, nearly wearable focus glasses, and then power amplification glasses. And many people don’t understand the difference between these lenses and their performance characteristics.


What we also found is that doctors don’t talk to their patients about their hobbies and how they use their eyes at work. And most of our patients believe that digital device-related eye strain is part of their lives.

Part of the reason I think doctors don’t talk to their patients about this is because they don’t know how to deal with these issues. And we’re going to give a very simple step-by-step approach to confidently recommending these types of lens designs and solutions.


Yes, and since we have so many lens designs, it’s very easy to add or increase your revenue by prescribing multiple pairs of glasses. And so we will also highlight successful fitting and how to increase sales of multiple pairs, as well as improving the patient’s overall daily activities using these types of lenses.

And we will also discuss many of the different product portfolios because there are so many lenses and not everyone uses the same lens. So it is nice to understand which products also exist.
