i've been using contact lense daily for few years..
no prob so far though for long hours..
recommended lenses are monthly disposable lenses by Bausch&Lomb.. affordable..
n de best solution is Solo Care Aqua by Ciba Vision..
less prone to dry eyes after using dis solution..

however, hygiene is de most important thing..
n please disposed de lenses on time..
do not exceed de allowed usage..
