My eyes has been suffering from myopia & astigmatism sinced middle school. At that time, the myopia caused by electronic watching/reading was -1.5 with right axis 1. Now, after I graduated from university, my myopia increased to -2.5 and both eyes suffered axis 1. Well, ever sinced middle school, although I owned glasses, I didn't intend to use it except in class. I ignored the fact that I must use glasses in everydays activities, including walking, studying, even driving a car! The bright and clearer vision effect in using glasses makes me avoiding it for these past years and although I don't use glasses, the increasing chance is minimal.
