A look at lens technology in 2021


By David Goldberg

Prescribing lenses isn’t just about achieving 20/20 vision.

Innovative manufacturing techniques have given us the opportunity to target specific weaknesses based on each patient’s unique set of circumstances. 

No matter the eye condition, the activity or even the weather, the industry’s top lens makers are constantly driving to enhance performance and maximize comfort for all. 

It’s time now for a closer look at some of the next-level advancements in lens technology. 



“We are very excited to offer Canadian wearers the latest in lens technologies. Transitions Xtractive 2.0 and Xtractive Polarized push the boundaries of performance to offer more protection inside and outside, in all kinds of light environments, with faster fadeback and darker activation,” says Mathieu Arsenault, Brand Manager at Transitions. 

Compared to the Transitions XTRActive lenses on the market today, this new generation is darker overall, darker in hot temperatures and in the car, and up to 35% faster to fade back. These advances are possible thanks to the new nano-composite matrix technology combined with new, extra powerful broad-spectrum dyes which activate in both the UV and visible light spectrum. 

Transitions XTRActive new generation lenses will be available in the U.S. and Canada in the third quarter of 2021 in grey, brown, graphite green as well as five mirror-styles. 




MiyoSmart is the safe, easy-to-use, effective non-invasive method to manage myopia in children.

The rate of Myopia in children is expected to climb over the next decade and so Hoya has developed MiyoSmart, an innovative lens for myopia control. It’s been proven to curb myopia progression in children on average by 60 percent* with its award-winning D.I.M.S. (Defocus Incorporated Multiple Segments) technologies.

The best part is, these lenses are built to withstand whatever a kid can throw at them, or whatever height they are probably going to drop them from. 

“The lenses are impact-resistant,” explains Hoya’s marketing manager, Dale Mouscos. “The lens is aesthetically pleasing with its smooth surface and near-identical appearance to single-vision lenses.”

MiyoSmart lenses also feature a MiyoSmart Coating, which includes anti-reflective, scratch-resistant, oleophobic and water repellent properties.




The average person spends over 11 hours per day viewing digital screens and so IOT Endless Plus lenses were designed to alleviate symptoms of eyestrain associated with the use of electronic devices. 

“People are looking for solutions to digital eye strain while they’re working in front of their computer all day,” says Plastic Plus Vice-president Jason Faibish. 

“Most products use some sort of coating but the blue blocking technology is actually built into the design of this lens, you then have an option to add a blue blocking coating onto this design. 

The secret is Digital Ray-Path 2 technology that personalizes your lenses, for crisp vision at all distances.

“IOT Endless Lenses are fully personalized and compensated for 3,149 individual directions of gaze,” explains Faibish. “Many elements that are unique to each patient are utilized in the creation of the design itself.

These elements include sitting height and PD but also the patient’s prescription, frame size and shape, the base curve of the lens and position-of-wear measurements. 

IOT Endless Plus lenses also give you comfort beyond digital devices, offering exceptional performance for any activity. 



With the ZEISS SmartLife portfolio, you can enhance the clear fields of view with single vision lens designs and reduce perceived blur with ZEISS’ Digital & Progressive lenses. 

“The larger fields of clear view were seen also in an analysis by ZEISS in 2019 for astigmatic lenses. In addition, the new SmartLife lens portfolio was successfully tested with various consumers irrespective of their prescription,” says Ob Hussain, Marketing Manager at ZEISS. 

 ZEISS’ latest design optimization also includes a state-of-the-art 3D object-space-modelling system adapted for today’s dynamic visual behaviour. 

“Both lead to a smoother transition between all viewing zones, resulting in comfortable vision and ease of viewing at all distances and in all directions,” explains Hussain.
