Keep a Good Posture Whilst Reading.
Poor posture while reading is a
major cause of weakened and fatigued eyesight.
Avoid slumping or hanging or craning your head down while reading. Sit
comfortably erect.
A slumped head position causes gravity to pull down on the eyeballs,
placing strain on the eye muscles, which have to hold the eyes back in the
sockets.
Holding this 'neck-bent downward’ position causes
lengthening/flattening of your eyeball, resulting in myopia or
nearsightedness.
Hold your book or reading material parallel, about twenty inches from your
eyes. Holding the print too close to your eyes is also a major cause of
myopia.
Don’t Read for more than 30 minutes at one time
. 30 minutes is about
the maximum time most people’s untrained eyes can handle without strain
or fatigue.
Read for a bit, then get up and walk around, stretch or go outside for a
breath of fresh air.
Look into the distance. Take a deep breath, bend over and rub your face,
forehead and around the eyes, exhale and stand up straight. Inhale again
and bend backward, then to each side, and exhale and relax your gaze.
Close your eyes and place your palms over your eye sockets and do some
palming (see the next chapter)
