The Ocular Parameter Changes Caused by Reading With Remote Image Optical Screen

This study aimed to analyze the differences in ocular parameter changes induced by reading with traditional electronic screens (TESs) compared with those associated with the remote image optical screen (RIOS), further evaluating the effects of RIOS on ocular parameters.

Thirty-five healthy participants (70 eyes) were enrolled in the prospective self-controlled study, completing two distinct reading tasks. Task A: near reading using TESs for 20 minutes; and task B: near reading with RIOS for an equivalent duration. The spherical equivalent (SE), anterior segment parameters, choroidal thickness (ChT), and choroidal vascular volume (CVV) were measured both before and after each reading task.

Following reading with TESs, significant myopic shifts were observed in the SE (P = 0.024), and there was a notable decrease in both anterior chamber depth and width (all P < 0.001). The lens thickness and vitreous chamber depth increased significantly (all P < 0.05). In the meantime, the ChT and CVV decreased significantly (P = 0.029 and P = 0.013, respectively), particularly beyond a region measuring 9 × 9 mm2 centered on the fovea (all P < 0.05). After reading with RIOS, no significant changes were detected in SE or any other ocular parameters, including ChT and CVV (all P > 0.05).

Reading with RIOS effectively alleviates myopic shift, ocular anterior segment changes, and choroidal thinning caused by traditional near work.

The study demonstrates that reading with RIOS can alleviate the ocular anterior segment changes and choroidal thinning caused by TESs. The RIOS may represent a promising strategy for myopic control.
