The effectiveness of ZEISS Digital Lens has been proven in stress tests carried out with smartphone and tablet users. Leaving more than 90 % of all respondents satisfied by reducing symptoms of strained or tired eyes by a factor of 4.
Sometimes we don't realize just how much strain our eyes are exposed to over the course of the day. We constantly shift our vision between close-up objects (book, smartphone), mid-range focus (navigation devices, PC) and long-range focus (driving) – and our eyes constantly adapt to these changing circumstances.
With increasing age, the lenses and muscles in our eyes gradually lose their elasticity, reducing our eyes' ability to automatically focus clearly at different distances. The resulting strain and fatigue leads to stress for us and our eyes.
A ZEISS digital eye stress test by your ZEISS eye care professional can show you how stressed your eyes already are and what you can do to tackle the problem.
