العلوم
هل تضرّ الشاشات المضيئة بعينيك؟
الجواب باختصار: لم يثبت ذلك بالفعل.
ليس هناك دليل مباشر على أن أجهزة التلفاز أو الحواسب أو الهواتف المحمولة تسبب قصر النظر. ولكن لا تزال هناك مخاوف في ما يتعلق بالآثار التي يمكن أن يخلّفها التحديق في الشاشات المضيئة. إذ تقوم العينان بضبط شكلهما للتركيز على "العمل القريب" في النصوص المطبوعة أو شاشات العرض الرقمية، ولذلك يبدو من المنطقي أن تؤدي فترات القراءة الطويلة إلى أضرار دائمة. ولكن كاثرين روز من جامعة سيدني تقول بأن هذا الافتراض لم تثبت صحته بعد. ويقول مارك روزنفيلد من كلية البصريات بجامعة ولاية نيويورك بأن التحديق في الشاشات يمكن أن يسبب إزعاجاً. وفي دراسة أجراها مختبره، أفاد نحو 40% من…
