There is a machlokes amongst the Achronim regarding if the Bracha of Kiddush Levanah is #1 made to celebrate the "renewal of the world i.e the new moon - this is the loshon of the Mishne Berurah) OR #2 because we derive benefit (i.e. we can see) from the moons light. The practical difference between these two reasons is a blind person. If the reason is to cerebrate the new moon than the blind person should say the bracha. If the reason is benefit the blind person derives no direct benefit (although he does benefit from other people who benefit from the light of the moon so he should say a blessing according to some Achronim)
Now in your case if you for what ever reason don't want to look at the moon - according to the Mishne Beruah who goes with reason #1 you still have to make the Brachah since you are no different than a blind person in this case. If with modern city lighting you still benefit from the moons light than even according to reason #2 you would have to make the Bracha but my experience is that the city lights drown out the effect of the moon. Seeing the the Biur Halacha makes a case for blind people not to say the Bracha you might want to ask your Rabbi if it's appropriate for someone to be motzai you in the Bracha.

I would be remiss if I didn't point out what a special Mitzvah Kiddush Levanah is and that one should try their hardest to say it on time and with a minyan.
