It used to be that only “old folks” had trouble with eye strain after reading or using computers at close range. Now, eye doctors are seeing more of these symptoms in people of all ages including teenagers through young adults! Why is this?
First we have to consider the soaring use of electronic devices. Not only desk-top computers, but usage of smart phones, tablets and laptops has all increased tremendously in the past decade. The largest group to embrace this technology has been the 15-30 age group. The sheer volume of time spent viewing these devices has dramatically increased, subjecting the user’s eyes to increased focusing effort from viewing material at close range. But the other unique aspect of most digital handheld devices is the distance from the eye. Compared to reading printed material, users of electronic devices have a viewing distance up to 25% closer, increasing the focusing effort over time spent. Finally, digital devices often have lower resolution and contrast vs. printed material.
All this adds up to the fact that the human eye is really not designed for comfortable viewing of electronic devices.
In response to this problem, Zeiss has developed a new lens. The Zeiss Digital Lens actually relaxes the eye while viewing close range electronic screens. It does this by a gradual change in lens power as the viewer looks down. This has the effect of reducing the total focusing effort a wearer has to put forth and less eyestrain over the course of the day.
