Screen use was linked to temporary eye-pressure increases at selected measurements
Trials in healthy participants and people with glaucoma measured pressure inside the eye during screen use. Increases appeared at selected times, with unclear implications for lasting eye health.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
During screen use, eye pressure rose at selected measurements in healthy participants and people with glaucoma. Other measured times showed no statistically clear changes. In the reported healthy-participant results, pressure afterward was not significantly different from the starting level. These short-term measurements do not establish lasting eye damage or changes in vision.
The abstract does not label its numerical intervals or report vision outcomes. The authors call for larger trials to confirm the pressure findings.
What researchers found
Pressure inside the eye
At 25 minutes versus before exposure: weighted mean difference +1.53 mmHg, with a reported interval of 0.83–2.24 mmHg. The interval type was not stated.
A time-specific finding
The healthy-participant increase appeared at a particular measurement, rather than consistently throughout screen exposure. Statistically unclear findings at other times do not prove that pressure was unchanged or establish a safe screen-use duration.
The glaucoma subgroup
Participants with glaucoma also showed pressure increases at selected measurements. The abstract does not establish that these changes worsened glaucoma, and its subgroup findings should not become general advice about screen use for everyone.
