Why does screen work make your eyes tired?
Mainly due to reduced blinking and prolonged focusing at the same distance. Your eye muscles maintain a fixed position and your tear film is less refreshed. Light plays a smaller role than most people assume.
This is important to know, as it explains why a filter alone is rarely enough. It doesn't address the main cause.
What are the causes, listed?
| Cause | Complaint | What helps |
|---|---|---|
| Less blinking | Dry, burning eyes | Conscious blinking, humidity |
| Fixed viewing distance | Tired eyes, blurred vision | Regularly looking into the distance |
| Contrast screen and room | Headache, squinting | Adjust ambient lighting |
| Uncorrected vision | Headache, neck pain | Eye test |
| Screen height and posture | Neck and shoulders | Screen at eye level |
That fourth point is most often overlooked. Those who have been wearing the same glasses for years while their prescription has changed often look for the cause in the screen.
Is blue light the culprit?
No. There is no evidence that blue light from screens damages your eyes, and the symptoms you experience have other, more explainable causes.
That doesn't mean light does nothing. A bright screen in a dark room increases the contrast your eyes have to bridge, and that takes processing. The difference between these two narratives is explained in is blue light bad for your eyes.
What works best?
Measures that relieve your eye muscles and tear film. They are free and more effective than any aid.
Regularly look away at something in the distance, consciously blink when you notice yourself staring, and ensure your ambient lighting is similar to your screen brightness. We elaborate on the best-known rule of thumb for this in improving focus during screen work.
When does a pair of glasses add something?
If your prescription is incorrect, or if looking becomes uncomfortable at the end of a long day while everything else is already in order. Then a filter is a supplement, not a solution.
Our FOCUS with clear lenses reduces visual strain without changing your color perception. If your prescription is incorrect, consult an optician first. If your employer cooperates, read computer glasses reimbursement.
