Seems like visual stress and fatigue have finally gone mainstream, and it’s due to a confluence of factors. A perfect storm of sorts, and Essilor is leading the way. (A tip of the cap to Essilor’s free online e-Book that is a collection of articles on eyestrain from 2005-2015 in Points de Vue.) A clever approach to lifestyle lens prescribing that takes into account the opportunity to address nearpoint function is the company’s Eyezen lens. Featured today in one of my favorites sources, New Grad Optometry, Dr. Courtney Dryer notes that the lens speaks the millennial patients’ language.
The hot topic in optometry these days is “blue light”, and the benefit of lenses that selectively block blue light have been touted just about everywhere. Blue light has become the ophthalmic version of good cholesterol/bad cholesterol. But if selective blue-blocking is good for eyeballs, what about nearpoint fatigue/stress factors related to sustained accommodation? Ah, that’s old school. Or is it?
Remember Skeffington’s admonition: nearpoint stress and visual maladaptation is triggered by socially compulsive, biologically unacceptable sustained neapoint tasks. Can you think of any better example of the socially compulsive/biologically unacceptable than embedding your eyeballs in a screen or tablet for extended periods of time?
Enter the Eyezen lens. While the blue blocking technology gets all the hype, note the reference here to the close and variable distance of visual demands these days.
How clever! Eyezen can be had in either a 0.4, 0.6, or 0.85 add. A way to sneak in “low plus at near” for non-presbyopes through the blue blocking back door. And no mention of a multifocal lens that might scare off the functionally disinclined. Brilliant!
