Eye pain after a forceful punch. This?

My husband hit my right eye with a high force.Immediately after that I felt a very high pain in my right eye.After a week of this eye trauma.I went to a local eye doctor they checked my eye using dilation and told that my retina is normal.They prescribed a megabrom eye drop for my right eye one drop twice for 15 days .After taking this for about 7 days , now I feel head pain along with eye pain and no improvement.Should I stop this or I have to continue this drop?.Though I went to the doctor and told them this issue but they are saying me to continue the same drop.May I know how long will it take my eye pain to get cured.I am feeling very scary.Is it compulsory to keep the eye closed most time to get cure the pain ? I am using laptop for studying .Do I need to stop this?
