The phone has shifted—once a device held to the ear, now it’s mainly held in front of the eyes. Such heavy usage puts a strain on our eyes.
Studies are still determining exactly how much our smartphones affect our eyes, but it’s clear that many people experience and suffer from eye strain due to prolonged smartphone usage.
Why do smartphones make our eyes tired? There are three reasons to consider:
- Small screens and small text are highly demanding on our vision.
- Blue light emitted by smartphone screens contributes to lower contrast.
- Rapid shifts of our focus from near to far puts strain on the focusing system of our eyes.
Using smartphones for long hours can lead to eye strain, causing symptoms such as dry eyes, blurry vision and headaches. Also, it can ultimately cause sleep problems such as difficulty falling asleep, or light sleep patterns.
Nikon offers lenses specially adapted for computer and smartphone users. These lenses come with a coating that cuts part of the blue light emitted by phone screens. They also feature a special optical design that provides some relief to the eye focusing system, allowing your eyes to relax.
