    injurious and fatal consequences of pressure upon the eyes; J It is, therefore, very easy to conceive, that even a mode- -I rate degree of pressure, if frequently repeated, as in the ;l above mentioned habit, may not only increase the ten- ■] dency always existing in many eyes to irritation and in- J flammation ; but may sometimes actually produce it, and lay the foundation of weakness that might otherwise I have never occurred. 2. The eyes, especially when they are predisposed to j weakness, are not unfrequently injured by exposure to 1 strong currents of wind. Many date the first attack of ?| what they consider serious disease, to this cause. All I whose eyes are weak, are rendered uncomfortable by it. I It should therefore be avoided, especially by those who I are subject to ophthalmic diseases. When it cannot be \ wholly avoided, such individuals ought to adopt some I measures to modify the impression of the wind upon the 1 eyes. A neglect of this precaution has often converted :| simple weakness into acute inflammatory disease. 3. Another bad habit is the custom of reading while 1 the body is in a recumbent position. It is a lazy posture, J as inconsistent with the health of the eyes, as with the 1 graceful propriety of the scholar. The blood, while the body is thus conditioned, flows more readily to the head 1 and eyes, and subjects them to increased danger, es- -I pecially when the reading or study is combined with | mental labour. 4. The eyes are often seriously injured by being put j to too early or too great use after the system has been I affected with grave and important disease; as acute in- J flammations of the vital organs, nervous fevers, or any i I disorder accompanied with great depletion. Such aft'ec- 1 tions often leave the eyes exceedingly debilitated. The i convalescence is very slow; time hangs heavily on the j hands of the student; he is weary with the labour of 1 idleness; and the temptation to lighten the burden by reading is very strong. But it cannot be done without danger of increasing the weakness of the eyes, and con- verting it into obstinate if not incurable disease. There is no condition where the safety of the eyes stands in 42
