What causes digital eye strain?
When focusing on a screen, people tend to blink less often, which reduces the natural moisture film on the eye's surface. Combined with sustained close-focus effort, this contributes to symptoms like dryness, fatigue, and blurred vision after extended use.
Common symptoms
- Dry or irritated eyes
- Blurred or strained vision after long sessions
- Headaches associated with screen use
- General eye fatigue by end of day
The 20-20-20 rule
A widely recommended habit is the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This simple break gives eye muscles a chance to relax.
Where nutrition fits in
Nutrients like Lutein and Zeaxanthin are commonly discussed in the context of general eye wellness, complementing habits like screen breaks and proper lighting. See our Lutein deep dive for more.
When to see an eye doctor
Persistent or worsening symptoms are worth discussing with an eye care professional, since they can sometimes indicate an underlying vision correction need or other condition.
