Diplopia, commonly referred to as double vision, occurs when a person sees two images of a single object. This condition can be monocular, affecting just one eye, or binocular, involving both eyes. Binocular diplopia disappears when one eye is closed, indicating issues like eye misalignment or neurological problems. The Singapore National Eye Centre (SNEC) has observed a significant rise in cases, aligning with global trends, which raises concerns about the underlying causes and preventive measures.
A primary factor contributing to the increase in diplopia cases is the prolonged use of mobile phones and other small screens. This excessive screen time requires intense focus, which strains the eyes. For instance, Madam Jeviene Sim experienced frequent double vision episodes, escalating in frequency and duration, correlated with her extensive smartphone use for watching videos, often spanning entire weekends. This case underscores the potential vision hazards associated with prolonged and uninterrupted screen exposure.
In response to these concerns, it is crucial to adopt proper eye care practices, especially in settings involving children, such as at Sheffield Kidsworld, where screen time is significantly restricted. Limiting the use of smartphones and tablets helps prevent the onset of vision problems like diplopia. Children are particularly susceptible to eye strain from excessive screen use, and it is important to encourage activities that involve physical play and interaction, which not only protect their vision but also support their overall development. At Sheffield Kidsworld, we prioritize outdoor activities and hands-on learning to ensure a healthy balance and support children's visual and physical health.
