Corneal abrasion...what can I take?

what can I take to make it easier to keep my eye open for longer until it heals? I went to the hospital today (it happened this morning) and I was told 2 days. in the meantime I sti;; have to take care of my two little ones. aspirin is not doing anything. I have a good tolerance of drugs..so what would anyone here suggest? and yes I was given a prescription but its not covered on my drug plan.
