الشاشات وصحة العين.. هل يضعف الهاتف والحاسوب البصر فعلا؟

ما يعرفه ريفو عن الخبر

لا تتلف الشاشات البصر لدى البالغين بل تسبب أعراضاً وظيفية مؤقتة كجفاف العين والإجهاد البصري.
ترتبط مدة استخدام الشاشات لدى الأطفال بقصر النظر وهو مرض بنيوي دائم وتزداد حالته مع زيادة الجرعة.
تعد قاعدة 20-20-20 وسيلة لتخفيف الأعراض على المدى القصير بينما لم تثبت النظارات المرشحة للضوء الأزرق فعاليتها.
ينخفض معدل رمش العين بشكل حاد أمام الشاشات مما يؤدي إلى تبخر الغشاء الدمعي وظهور أعراض الجفاف والحرقة.

تسبب الشاشات للبالغين أعراضا مؤقتة كجفاف العين والإجهاد البصري دون تلف دائم، أما لدى الأطفال فتزيد من خطر إصابتهم بقصر النظر الدائم. تخفف قاعدة 20-20-20 الأعراض مؤقتا، ونظارات الضوء الأزرق غير فعالة.
