Neither do you need to tie cloth on your eyes nor to walk closing your eyes. Just you should lower your gaze, this has been ordered in the Holy Quran. One can also raise up your eyes when you need to see the way etc. However, you should avoid seeing any non-Mahram intentionally and if suddenly or by coincidence you happen to see, you should immediately divert your eyes form there. By doing so punctually, you will get the status of piety (taqwa), in-sha-Allah.
