عيب بصري، يري المصاب به الأجسام البعيدة بوضوح، والقريبة مشوهة غير واضحة
Hyperopia, commonly called far-sightedness, is a condition where your eyes focus light behind the retina instead of directly on it, making nearby objects appear blurred while distant ones stay clear. It matters because while mild cases may go unnoticed due to your eye's natural focusing ability, severe hyperopia causes blurred vision and eye strain during close-up activities like reading.

مد البصر أو طول النظر أو بُعد النظر ( Hyperopia, أو hypermetropia) هي نوع من أنواع تأثر البصر بسبب شكل غير متكامل للعين (عادة لان كرة العين تصبح قصيرة أو عندما عدسة العين لا تستطيع أن تصبح مدورة بشكل كافي) تسبب عدم استطاعة الفرد عن التركيز على الأشياء القريبة، وفي حالات قوية عدم استطاعته التركيز على أي شيء بغض النظر عن المسافة. كلما يتحرك جسيم قرب العين، يجب على العين ان تزيد من قوتها لتبقي الصورة على الشبكية. إذا قوة القرنية أو العدسات يصبحان غير كافيان، كما في بعد النظر، تصبح الصورة مشوّشة.
