Core Viewpoint - The recent discussions around the health risks associated with using mobile phones while lying down, particularly the potential impact on vision and spinal health, have gained attention due to anecdotal reports from individuals experiencing significant vision discrepancies and discomfort [1][2][3] Group 1: Vision Health Risks - Experts advise against prolonged use of mobile phones while lying on one side, as it may contribute to vision issues such as strabismus and anisometropia, especially in adolescents whose eye development is not yet stable [1][2] - A case was noted where a male individual reported a 500-degree difference in vision between his eyes, attributed mainly to congenital factors rather than the side-lying position [2] - Long-term use of electronic devices can lead to eye fatigue, with symptoms including nausea and vomiting, particularly when used in low-light conditions [2][3] Group 2: Spinal Health Risks - Using mobile phones while lying on one side poses risks to spinal health, as it increases pressure on the spine compared to lying flat, potentially leading to conditions such as scoliosis and lumbar disc herniation [2] - The contact area between the body and the bed decreases when lying on one side, causing the spine to bend and rotate under increased gravitational force [2] Group 3: Recommendations for Mobile Phone Use - It is recommended to maintain a distance of at least one arm's length between the eyes and the phone screen, avoid lying down or side-sleeping while using the device, and ensure adequate lighting to reduce eye strain [3] - Users should take breaks every 20 minutes to look at distant objects for 20 seconds to alleviate eye discomfort [3] - Immediate medical attention is advised if symptoms such as dryness, light sensitivity, or pain occur after prolonged use [3]
