【摘要】 目的　探讨书写力度与近视的关系。方法　根据 35 3名大学四年级在校学生书写力度的相对大小 ,将不同性别分为书写力度较大、中等和较小 3组。然后对各组的近视率、近视发病平均年龄进行了分析。结果　各性别按书写力度较大、中等和较小 3组的近视率分别为 90 .0 %、83.1%、6 3.3%(男 ) ;和 85 .7%、78.7%、75 .5 %(女 )。在男性中差别具有非常显著性 (P <0 .0 1)。在近视患者中 ,书写力度较大的组别近视发病平均年龄较书写力度较小的组别有提前现象。 3组别近视患者的平均发病年龄分别为 14.4岁、15 .6、16 .0岁 (男 ) ;和 15 .1岁、15 .6岁、15 .6岁 (女 )。结论　书写力度普遍较大可能是目前学生近视率较高的重要原因之一。更多还原

【Abstract】 Objective:To study the relationship between the writing physical strength and myopia.Method:The writing physical strength was measured through 353 seniors in a college .According to sex ,these strdents was divided into six groups with heavy ,medium and light writing physical strength .Then analysis was made in accordance the rate of myopia,the average age when they felt myoipia coming on.Results:The rate of myopia with heavy writing physical strength is higher than those with light writing physical strength.The rate of myopia of male groups according to writing physical strength is 90%,83.1%,63.3%respectively;and those of female groups is 85.7%,78.7%,75.5%,In the three groups of each sex ,the average age when they suffered from myopia with heavy writing physical strength is younger than those with light writing physical strength .Their average age when they suffered from myopia is 14.4 years old,15.6 years old,16 years old (male);and 15.1years old,15.6 years dd,15.6 years old (female).Conclusion:At persent ,the writing physical strength of students writing with pen or pencil is heavier than that of the students who wrote with brush half a century ago.
