Intraocular pressure change during reading or writing on smartphone.

ABSTRACT:

Purpose

To investigate the effect of reading or writing on a smartphone in terms of intraocular pressure (IOP) changes.

Design

Prospective, comparative case series.

Participants

Thirty-nine (39) healthy young (age < 40) volunteers.

Methods

The participants were requested to conduct standardized work (i.e., read a sample text on single mobile device and subsequently type it on the same device) under daylight [300 lux] and low-light [100 lux] conditions independently on consecutive days. On each day, three sets of IOP measurements (total: 7) using a rebound tonometer (iCare PRO; Tiolat, Helsinki, Finland) were performed: (1) pre-work (baseline) [2 measurements], (2) during smartphone work [5, 15, and 25 minutes], and (3) post-work [5 and 15 minutes].
