Efek Samping Penggunaan Komputer

	Negative Effects of Computer Use Efek Negatif Penggunaan Komputer
	While most Americans have heard of Carpal Tunnel Syndrome, not as many have heard of Computer Vision Syndrome (CVS). Sementara kebanyakan orang Amerika telah mendengar Sindrom Carpal Tunnel, tidak seperti yang banyak mendengar Komputer Vision Syndrome (CVS). This condition most often occurs when the viewing demand of the task exceeds the visual abilities of the computer user. Kondisi ini paling sering terjadi ketika permintaan melihat tugas melebihi kemampuan visual dari pengguna komputer. The American Optometric Association defines CVS as that 'complex of eye and vision problems related to near work which are experience during or related to computer use'. American Optometric Association mendefinisikan CVS sebagai yang 'kompleks masalah mata dan penglihatan yang berhubungan dengan pekerjaan dekat yang pengalaman selama atau berhubungan dengan penggunaan komputer. The symptoms can vary but mostly include eyestrain, headaches, blurred vision (distance and/or near), dry and irritated eyes, slow refocusing, neck and/or backache, light sensitivity, double vision and color distortion. Gejala-gejala dapat bervariasi tapi kebanyakan termasuk kelelahan mata, sakit kepala, penglihatan kabur (jarak dan / atau dekat), mata kering dan iritasi, memusatkan lambat, leher dan / atau sakit punggung, kepekaan cahaya, penglihatan ganda dan distorsi warna. The causes for the inefficiencies and the visual symptoms are a combination of individual visual problems and poor office ergonomics. Penyebab inefisiensi dan gejala visual adalah kombinasi dari masalah visual individu dan ergonomi kantor miskin. Poor office ergonomics can be further divided into poor workplace conditions and improper work habits. Ergonomi kantor Miskin dapat dibagi lagi ke dalam kondisi kerja yang buruk dan kebiasaan kerja yang tidak tepat. A survey of computer users by NIOSH in 1991 concluded that two-thirds of the complaints were related to vision problems while one-third was due to environmental factors. Sebuah survei pengguna komputer oleh NIOSH pada tahun 1991 menyimpulkan bahwa dua-pertiga dari keluhan yang terkait dengan masalah penglihatan sementara satu-ketiga adalah karena faktor lingkungan. Many people have marginal vision disorders that do not cause symptoms when performing less demanding visual tasks. Banyak orang memiliki gangguan visi marjinal yang tidak menyebabkan gejala-gejala ketika melakukan tugas visual yang kurang menuntut. However, it has also been shown that computer users also have a higher incidence of complaints than non-computer users in the same environment. Namun, juga telah menunjukkan bahwa pengguna komputer juga memiliki insiden yang lebih tinggi dibandingkan non-keluhan pengguna komputer di lingkungan yang sama. When considering the relationship of CVS to the eyecare industry, consider that there are roughly 85 million eye exams performed every year. Ketika mempertimbangkan hubungan CVS untuk industri perawatan mata, pertimbangkan bahwa ada ujian mata sekitar 85 juta dilakukan setiap tahun. Of those, about 17% are initiated due to symptoms related to computer use. Dari mereka, sekitar 17% yang dimulai karena gejala yang berkaitan dengan penggunaan komputer. That translates into approximately $1.15-2 BILLION cost to the US economy. Yang menerjemahkan menjadi sekitar $ 1,15-2 MILIAR biaya untuk ekonomi AS. Some people whose jobs involve intensive keyboard use have reported experiencing pain in their wrists, arms, and neck. Beberapa orang yang pekerjaannya melibatkan menggunakan keyboard intensif telah melaporkan mengalami nyeri pada pergelangan tangan, lengan, dan leher. This type of disorder has been variously categorized as regional musculoskeletal disorder (R-MSD), cumulative trauma disorder (CTD), and repetitive stress injury (RSI). Jenis gangguan ini telah banyak gangguan muskuloskeletal dikategorikan sebagai daerah (R-MSD), gangguan trauma kumulatif (CTD), dan cedera stres yang berulang (RSI). These are "catch-all" terms that refer to a variety of soft-tissue ailments in the upper limbs such as tendonitis, tenosynovitis, rheumatism, and carpal tunnel syndrome, and are not specific medical diagnoses. Ini adalah "menangkap semua" istilah yang mengacu pada berbagai penyakit jaringan lunak pada tungkai atas seperti tendonitis, tenosinovitis, rematik, dan sindrom carpal tunnel, dan tidak diagnosa medis tertentu. A qualified medical practitioner to define the precise nature of the disorder, institute appropriate treatment, and identify causal or aggravating factors amenable to modification should evaluate pain or discomfort that persists or impairs normal activities. Seorang praktisi medis yang memenuhi syarat untuk menentukan sifat yang tepat dari gangguan, lembaga perawatan yang tepat, dan mengidentifikasi faktor-faktor penyebab atau yang memberatkan setuju untuk modifikasi harus mengevaluasi rasa sakit atau ketidaknyamanan yang terus-menerus atau merusak aktivitas normal. When any of these conditions develop related to work factors, they are collectively known as Work-related Musculoskeletal Disorders (WRMSDs). Ketika salah satu kondisi ini mengembangkan faktor-faktor yang berhubungan dengan pekerjaan, mereka secara kolektif dikenal sebagai Kerja terkait Gangguan otot (WRMSDs). Let's take a look at some of the general definitions of MSDs and compare them to CVS. Mari kita lihat beberapa definisi umum dari MSDS dan membandingkannya dengan CVS. The symptoms of WRMSDs are work-related and associated with repetitive activity; the problems are related to disorders of muscles, tendons, bones and nerves; problems occur or are aggravated by repeated movements and a lengthy time is required for problems to develop and for the person to recover. Gejala-gejala WRMSDs yang terkait dengan pekerjaan dan terkait dengan aktivitas berulang, masalah yang berkaitan dengan gangguan otot, tendon, tulang dan saraf; terjadi masalah atau diperburuk oleh gerakan berulang-ulang dan waktu panjang diperlukan untuk masalah untuk mengembangkan dan untuk seseorang untuk pulih. All of these conditions exist for MSDs and for CVS as well. Semua kondisi ini ada untuk MSDS dan untuk CVS juga. Thus, it is logical to say that CVS is a musculoskeletal disorder that deserves special attention and treatment. Jadi, adalah logis untuk mengatakan bahwa CVS adalah gangguan muskuloskeletal yang layak perhatian dan penanganan khusus. The three areas that we'll be discussing regarding CVS are: 1. Tiga daerah yang kita akan membahas tentang CVS adalah: 1. The computer hardware 2. Perangkat keras komputer 2. The computer using environment 3. Komputer menggunakan lingkungan 3.
