umm. those ones are contacts (duh); there are 3months, 6months, or one year to use them. after the expirary date, those contact lenses cannot be used. otherwise ...yeahh. they cost a lot too......*cries*

but you have to be careful about using them, because you might be allergic to the material it is made from. the better quality ones are mainly from japan or korea, any country's isnt as good. not to use them too often, because soon your vision will start to get blurry !
