How accurate is subjective reporting of near work and outdoor time?

Young adults wearing the spectacle-mounted Clouclip device to measure viewing behaviour and light exposure also kept an activity diary. Mean daily near work and outdoor time were subjectively reported at about 150% of the objectively measured hours. This indicates the value of objective measures in research, as well as for clinical education and behaviour modification tools in future.

Outdoor time works to delay myopia onset – proof from Taiwan

A country-wide intervention to increase outdoor time in 5-6 year olds resulted in the prevalence of myopia decreasing from 15% in the 2014 cohort (before the intervention) to 8% in 2016 cohort (exposed to the intervention for up to two years) and was stable for three years thereafter. Increasing outdoor time works! 

How outdoor time influences myopia prevention and control

There is general widespread accepted belief that increasing time spent outdoors can be protective against progression of myopia. Xiong et al set out to better understand the research by performing a meta-analysis of 51 clinical trials and longitudinal studies that investigated the relationship between time spent outdoors and the risk of either developing myopia, progression of existing myopia or a myopic shift in refractive error.

Smartphone use in myopic vs non-myopic Irish students

This paper investigates the relationship between myopia, the objective measure of smartphone data usage and self reported duration of smartphone use in school children and university students with a secondary aim to assess whether study outcomes changed with age.
