With the passage of time, it is normal for many people to develop cataract in their eyes. A simple surgery usually ensures that the vision is reinstated to even better than before. A lens that suits your body type and profession would be inserted and upon completion of the surgery it is necessary to be conscious of same for a few weeks. Straining your eyes, staring at bright lights or fire, sudden changes to the angle of vision or bending over for too long may affect the success of the surgery. Therefore it is important to have a discussion with your eye care specialist beforehand and even afterwards. Eye pressure and other complications which do not warrant surgery may require daily administration of medicine, precautions in terms of exposure, straining and daily routine. These need to be understood under the supervision of the eye specialist or optometrist such that you do not inadvertently injure your eyes.
