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]

Core Viewpoint - Eye fatigue is a significant issue for entrepreneurs, often overlooked amidst the focus on financing, product iteration, and team management. It can lead to various symptoms that affect overall well-being and productivity, highlighting the importance of eye health in daily routines [1][2]. Group 1: Symptoms and Effects of Eye Fatigue - Common symptoms of eye fatigue include dryness, soreness, blurred vision, and headaches, which can lead to decreased work efficiency and overall discomfort [1][2]. - Prolonged exposure to screens causes the ciliary muscles in the eyes to remain tense, resulting in eye fatigue and potential vision decline [2][3]. Group 2: Bad Habits Affecting Eye Health - Incorrect mobile phone usage posture, such as lying down or looking down for extended periods, can lead to conditions like acute comitant esotropia and increased strain on the neck and spine [5]. - Using screens in poorly lit environments or with inappropriate brightness can exacerbate eye strain, leading to conditions like glaucoma [6]. - The use of privacy screen protectors can reduce screen brightness, forcing the eyes to work harder to see content, which can increase fatigue [7]. - Wearing improperly maintained glasses or contact lenses can lead to further eye strain and potential vision issues [8]. Group 3: Additional Factors Impacting Eye Health - Expired eye drops can lead to infections and serious complications if used beyond their recommended period [9]. - Rubbing the eyes can cause damage to the cornea and increase the risk of infections due to bacteria on the hands [10]. - The use of unwashed eye masks can lead to infections, while improper lighting in living spaces can contribute to eye fatigue [10]. Group 4: Recommendations for Eye Care - Awareness of eye fatigue as a silent threat is crucial, and correcting bad habits is necessary to prevent further deterioration [11]. - Maintaining proper lighting, adjusting screen distance, and taking regular breaks can help alleviate eye strain [11].
