There is no recommended screen time as it depends very much on the nature of the activity. According to the American Academy of Paediatrics (2016), there is no one-size-fits-all approach to limiting the amount of screen time for teenagers. The academy recommends that screen time takes into consideration a child’s developmental stage, how the technology is used, the quality of the content and design of the material. Schools will design their learning programmes to ensure that the students’ use of PLDs is balanced in relation to other activities and modes of learning.

Taking regular breaks from screen time is essential for maintaining good eye health. The American Academy of Ophthalmology recommends following the "20-20-20 rule" to give our eyes a break. This means that for every 20 minutes of screen time, we should look away from the screen and focus on something 20 feet away for at least 20 seconds. This practice helps to reduce eye strain and fatigue caused by prolonged screen use.

All PLDs will be installed with DMA, which allows teachers to manage students’ screen time if they so desire. Teachers will also continue to ensure that the amount of assignments set (both online and offline) is guided by the school’s homework policy.
