Mastery of the eyes requires reviewing the laws and consistent study of the pertinent topics. Therefore, keep the book with you and go through it periodically. Now that you know much of the ideas, you might prefer to read the book straight through in a few sittings. Or perhaps, turn to key parts that address the specific issues at hand.
In addition, you can study the book with a partner or ask your Rabbi to give a class on Shmirat Einayim, using the sources of his choice.
"The creation of man was for his ultimate existence in the World to Come. Therefore, Hashem endowed him with a precious soul. With his soul he is able to serve Hashem and to receive his eternal reward in its right time and place. Therefore, the existence of the soul in this world is beloved and pleasant to the soul." (Mesilat Yesharim, Man's Duty in his World):
Each word of Torah study, each second of contemplation and each effort we make to control our eyes will uplift and sanctify us. There is no greater joy than attaining holiness and purity!
May Hashem bless your efforts to master your eyes. May our collective effort to serve Hashem awaken great mercy in Heaven, so that we merit seeing the redemption of Klal Yisrael and the restoration of the Shechinah to the Kodesh HaKadashim.
"May Yisrael rejoice in its Maker; let the children of Zion rejoice in their King." (Tehillim 149:2)
