The Gemara tells us that were some Rabbis Who looked a woman and praised Hashem. The Gemara asks, it is permitted to look a woman? The Gemara responds that they had seen the woman by accident. Commentators explain that the whole life is a Nisayon. On the computer, Nisayon. On the street, Nisayon.
In the moment a woman passes don't look at her,  Pray to Hashem like this: Hashem, I can look at her. In fact, I want to look. But, I will make your will and i will not look. Then, ask whatever you want: Health, Parnassah children, etc. and Hashem will fulfill it.

We all want to be Tzadikim, right?
There are many ways to be a Tzadik, like staying day and night studying. But, there is a equal and much easier way: The moment a woman passes, do not look at her. There, Chazal says, you are called a Tzadik. Also, your tefillah is compared to that of the Kohen Gadol.

In the time of the Beit Hamikdash, The Kohen Gadol entered to the Kodesh Hakodashim and said 10 times Hashem´s name "Havaya" (Yud-Kei-Vav-Kei). That in Gematria is 260.

We humans have 2 eyes. In Hebrew, the word eye (Ayin) is in Gematria 130. Then, 2 eyes (130+130)=260, Just like the Kohen Gadol tefillah!
 So, if we take care of what we see, Our tefillah will be just as powerful as that of the Kohen Gadol. It is a good advice the next time we are tempted, and the Yetzer Hara wants to make us fall, we will win, because:
"Maalin BaKodesh veLo Moridin" ("We ascend in Holiness and we not descend").
Beshem Hashem Naase V´natzliach, Amen Ken Yehi Ratzon. ("In the name of G-d we will do and we will success").

It is very hard to avoid looking at a woman when walking.
I think because it is programmed into us as men to look at her, to asses her attractiveness, her suitability to be a "mate."

So we have to act against what is natural.

I have never foudn any kind of tric to do this.

I simply remind myself that a Jew should guard one's eyes.

For the record, I will often look for a split-second by instinct, then have the thought that this is not right, then look away.
I do not feel bad about this, as I think there is also a comm sense idea that one should at least be aware of other people walking along so as not to bump into them!

Its true. its natural, it is in our "chip" look at women. but, If we make a minimal  effort to do Hashem´s will, to not look at women, We will make Huge results. The first look is normal. The problem is the 2 look. You can by accident look a woman, and quickly look away. That's perfect But, when you know all the benefits of looking away, you can think 2 times before looking the 2 time. 
Think about it.
