Maternal knowledge, perceptions and practices regarding screen exposure and visual health among under-five children in Ibadan, Nigeria: a cross-sectional study
This cross-sectional study in Ibadan, Nigeria, reveals that while maternal knowledge and perceptions significantly influence screen-regulation practices for children under five, poor practices remain prevalent despite moderate knowledge levels, highlighting the need for interventions that combine eye-health literacy with practical household routines.

In the modern household, the glowing rectangle of a smartphone or tablet has become a constant companion for young children. It serves as a source of entertainment, a tool for learning, and often, a quieting device for a restless toddler. This ubiquity has sparked a genuine concern among parents and health experts: how much screen time is too much for a developing eye? Global health organizations have offered clear guidelines, suggesting that children under two should generally avoid sedentary screen use, while those between two and five years should be limited to about one hour of high-quality content daily. These rules are not just about the eyes; they are about ensuring children have enough time for sleep, outdoor play, and face-to-face interaction, all of which are vital for healthy development. Yet, knowing a rule is one thing, and following it in the busy, demanding reality of daily life is another. The gap between what parents know they should do and what they actually do remains a significant puzzle for public health researchers.
To understand this gap, a team of researchers in Ibadan, Nigeria, turned their attention to the mothers of young children. They wanted to see if a mother's knowledge about screen time and eye health actually translated into the habits she set for her family. The study focused on 420 mothers with children under five years old, a group where the child has no say in their own screen exposure; the adult is the sole gatekeeper. The researchers asked these women a series of questions to measure three things: what they knew about the risks and recommendations, how they felt about the role of screens in their lives, and what they actually did to manage their children's device use. They looked for patterns to see if knowing more led to doing better, or if other factors were at play.
The results revealed a complex picture where knowledge and action were not perfectly aligned. On average, the mothers in the study had a moderate level of understanding. Nearly half of them possessed a fair grasp of the recommendations, and about a third had good knowledge. For instance, most knew that children under one year should have no screen time and that using devices in a dark room is harmful. However, significant gaps remained. Less than half of the mothers knew that a child's first comprehensive eye exam should happen before their first birthday, and only about half were familiar with the "20-20-20" rule, which suggests taking a break every 20 minutes to look at something 20 feet away for 20 seconds to reduce eye strain.
Despite this moderate level of knowledge, the actual practices observed were far from ideal. The study found that nearly two-thirds of the mothers engaged in poor protective practices. This meant that many were allowing screens during meals, using tablets to calm tantrums on a daily basis, or failing to set any time limits or parental controls. A striking 77.6% of the mothers had never taken their under-five child for a routine eye check-up, often waiting until the child complained of a problem or showed obvious signs of squinting. This suggests that even when a mother knows screens can be harmful, the daily pressures of childcare, work, and the need to keep a child occupied often override those concerns.
The researchers discovered that a mother's knowledge and her feelings about the situation were both strong predictors of her behavior. Mothers who knew more about eye health and who held stronger beliefs about the importance of protecting their child's vision were more likely to enforce better screen-time rules. However, the study also showed that simply having knowledge was not enough to guarantee good habits. Even among those with fair or good knowledge, many still struggled to implement protective measures. This indicates that the barrier is not just a lack of information, but rather the difficulty of changing deep-seated routines and finding feasible alternatives in a world where screens are everywhere.
The data also challenged the idea that a mother's education or income level was the deciding factor in how she managed her child's screen time. While wealthier and more educated mothers tended to know more about the rules, these advantages did not automatically translate into better practices once the researchers accounted for the mothers' knowledge and perceptions. This suggests that the daily struggle to limit screen time is a universal challenge that affects families across different economic backgrounds, driven more by the immediate needs of the household than by a lack of resources or education.
Ultimately, the study concludes that telling parents what is right is only the first step. The real work lies in helping families build practical routines that make healthy choices easier. This includes creating screen-free zones during meals and before bed, finding non-digital ways to soothe a distressed child, and prioritizing outdoor play. It also means shifting the focus from waiting for a child to complain about their eyes to seeking routine professional check-ups early on. The findings suggest that effective support for families must go beyond simple awareness campaigns. Instead, it needs to offer concrete, manageable strategies that fit into the chaotic reality of modern parenting, helping mothers feel confident that they can protect their children's vision without sacrificing the practical benefits that technology can offer.
