Over 60 percent of computer users have problems related to neck and shoulder pains, while 24 percent indicated that the pain has disrupted their daily lives, revealed1 a research by the Institute of Occupational Safety and Health under the Council of Labor Affairs. Using a computer mouse for more than four hours a day is a big no-no2 if you want to avoid neck and shoulder pains.
勞委會職業安全衛生研究所的調查指出，百分之六十以上的電腦使用者有與頸部與肩膀疼痛相關的問題，而百分之二十四指出疼痛已影響到他們的日常生活。如果您想避免頸部與肩膀疼痛，一天絕對不要使用電腦滑鼠超過四個小時。

While such aches may not pose3 an immediate threat, they could result in reduced work efficiency and could affect sleep quality, moods and daily life in general. If neck and shoulder pains are allowed to go untreated or are not treated correctly, pathological4 deterioration5 of muscles and bones could result, making it difficult to cure.
這樣的疼痛也許不會立即構成威脅，但會導致工作效率減低，而且可能影響睡眠品質、心情及一般日常生活。如果放任頸部與肩膀的疼痛不治療或沒有適當地治療，可能導致肌肉和骨骼的病況惡化，而難以醫治。

Experts advised that computer users should wear a pair of weaker eyeglasses when using computers and they should take a break, stand up, and do some stretches6 at least once every two hours. Computer users should pay more attention to their posture7 and the upper body should be held upright8 and allowed to lean9 naturally against the backs of chairs and that the head and neck should never be tilted forward.
專家建議，打電腦時，使用者應配戴度數較輕的眼鏡，至少每兩個小時應休息一下、站起來、做一些伸展活動。電腦使用者應多注意自己的姿勢，上身保持直立，並自然地靠著椅背，頭部和頸部不要向前傾斜。

You are suggested go to optometrists and ask for a pair of "computer glasses", which are a weaker prescription especially made for near-work use. If you wear contact lenses you can wear "plus lenses" (also known as reading glasses) over them when reading. 
建議你找驗光師配一付「電腦眼鏡」 （為近距工作者特製，度數較輕的眼鏡），如果你戴隱形眼鏡，閱讀時可以再加戴「正視鏡」（又稱閱讀鏡）。
