There is a constant evolution of Progressive lens technologies. While the overwhelming trend is for each advancement in lens technology to improve the patient wearing experience, there are occasional hiccups along the way which do not perform “as advertised.”
As your Optical “Jedi” I have taken it upon myself to test out as many of these new lens advancements by wearing them myself. At this stage in my optical career, I have been wearing progressive lenses for 8 years and have personally worn and tested 54 lens designs.
New Varilux X Design
Just two weeks ago, the latest lens design from Varilux hit the market. Varilux is probably the best known brand name of progressive lenses by patients. They were at the forefront of developing the “No Line” lens back in 1959 and have continued to be amongst the leaders in lens designs.
As a disclaimer, I will admit that I have worked in many practices that have had an active partnership with Varilux and it’s parent company Essilor. This has allowed me to test more of their lenses than most competitors and I know there are many designs from competitors with great reputations. In fact, I have many lenses from several manufacturers which I recommend, based on patient scenario.
Despite my higher exposure to Varilux branded progressive lenses, I do not always feel their latest lens developments are indeed the best products available to meet patients’ needs. Often, their latest developments seem to niche, helping one type of prescription better than another.
I have been wearing my new Varilux X Design for just about a week, and not to put too fine a point on it, I’m thoroughly impressed. The wearing experience has been incredibly comfortable, and it has been one of the fastest lens adaptations I’ve experience.
There is no such thing as the “perfect lens.” Every design has some zone that is out of focus, or has issue with the vision rocking, bulging, or swimming. This lens is not “perfect” either, but it’s easily the closest to perfect I’ve experienced. According to the manufacturer, the lens was developed over 5 years of research into a different way of mapping the power distribution across the lens.
The point of the research is to try and improve the wearing experience for the modern world. The advent of the digital devices, such as smart phones and tablet computers, have had a dramatic impact on how we utilize our near vision. Traditional progressive lens designs stagger your zones to take advantage of the way we used to look at the world (i.e. top is distance, middle is desktop computer distance, bottom is book distance). Of course, since the personal digital device explosion, the reality of where we need to see and at what distance we need to see has changed. The new Varilux X Design is attempting to address this change.
So far, I will say this has been an admirable attempt to address the issue of where we look. There are still spots where I have difficulty finding a crisp focus, but there are in the usual trouble zones of the bottom corners of the lenses. In the meantime, however, I can focus at full near while in the “mid-range” zone and I can find the mid-range in the “blurry periphery.”
The Varilux X Design lens will be going on the VSP formulary in just a couple of weeks and I have to say just after one week of wear, I’m ready to call this my absolute go-to lens for almost all conceivable patient scenarios.
