Rules For The Preservation Of The Sight.
RULES FOR THE PRESERVATION OF THE SIGHT .
THOUGH it may be impossible to prevent the absolute decay of sight , whether arising from age , partial disease , or illness , yet by prudence aud good management , its natural failure may certainly be retarded , and the general habit of the eyes strengthened , which good purposes will be promoted by a proper attention to the following
maxims : i . Never to sit for any length of time'in absolute gloom , or exposed to a biaze of lig ht . The reasons on which this rule is founded , prove the impropriety of going hastily from one extreme to the other , whether of darkness or of light , and shew us , that a southern aspect is improper for those whose sight is weak and tender . 2 Not to read in the dusk if the be disorderedby

consequences 3 . The eye should not be permitted to dwell on glaring objects , more particularly on first waking in a morning ; the sun should not of course be suffered to shine in the room at that time , and a moderate quantity of light only be admitted . It is easy to see that , for the same reasons , the furniture of a bed should be neither altogether of a white or red colour ; indeed , those whose eyes are weak would find
considerable advantage in having green for the furniture of their bedchamber . Nature confirms the propriety of the advice given in this rule : for the light of the day comes on by slow degrees , and green is the universal colour she presents to our eyes . 4 . The long-sig hted should accustom themselves to read with rather less liht ^ ' and somewhat nearer to the eyethan what they
