I appreciate your request, but I notice that no context has been provided for me to base the overview on. Without source material to draw from, I cannot write an accurate overview based solely on the context you've specified. Please provide the context you'd like me to use, and I'll be happy to write a 2-sentence overview of myopia for a general reader.

قصر النظر أو الحسر (بالإنجليزية: Myopia) هو إحدى أشكال ضعف البصر حيث تسقط بؤرة الضوء أمام الشبكية وهو عكس ما يحدث في حالة طول النظر وكلاهما يعد نتيجة خطأ في وضعية الصورة. وفي معظم الحالات لا يعد قصر النظر كحالة مرضية ولكنه مرتبط بميل جيني ولكن يمكن اعتبار قصر النظر المركب«المانجن» حالة مرضية. ينجم الحسر أو قصر النظر بشكل رئيسي عن شكل المقلة، فيكون محور المقلة زائد الطول بحيث يكون الإبصار القريب (كالقراءة والكتابة) ممتازا، أما الأجسام البعيدة فتكون ضبابية.عادة ما يبلغ طول محور العين السليمة-الذي يمتد من القرنية الي الشبكية- 2.4 سم عند هذا الطول لمقلة العين يلتقي شعاع الضوء في بؤرة العين علي الشبكية حيث تكمن الرؤية السليمة.
