Hi there and thanks for the questions. I agree that custody of the eyes is kind of an old-fashioned term and not one we use or, for that matter, practice much today, but in a congregation such as the Poor Clares or the Trappistines, for instance, it is a significant value which has a good deal less to do with avoiding lustful feelings and more with protecting the privacy, and more, the silence of solitude of one's Sisters and of the house more generally. Interestingly, custody of the eyes is meant to be combined with a genuine sensitivity to the needs of one's Sisters (or others more generally); for instance, one is expected to be aware if someone needs something at table and offer it, or to do something similar in work situations with tools and materials being used, so custody of the eyes does not mean closing oneself off to others, cultivating general unawareness, isolation, or anything similar. I think custody understood in this more balanced way is one of those values we ought all to cultivate as appropriate to our own states of life. It seems to me in some ways it is a vital practice our own technological and media-driven world really needs.


Custody of the eyes allows a person to attend to their own hearts without constantly being distracted by the activity and sights around them. Especially, as it does this, it assists us in becoming people who see things truly, that is, who see things as God sees them. Moreover, it provides space and the gift of privacy for others with whom one lives; especially it provides for the communion we call "the silence of solitude" in which they too are seeking to dwell so that they too may be persons who see as God sees. Custody of the eyes intends our living with focus; it fosters the containment and denial of the incessant voice of curiosity and even prurience that has been intensified with the computer and social media environment and assists in following through on a project without getting distracted. (N.B., even the monastic cowl or cuculla ("hood") helps us maintain custody of the eyes and appropriate focus.) Thus, I think, the practice of custody of the eyes is rooted in a true reverence for others and for ourselves even as it helps create an environment where others may experience the same.
In a cloister or a lavra, for instance, silence does not cut us off from others or the demands of love. It is not a neutral reality but one that is carefully cultivated and allowed to flourish in love for the others who are also seeking God just as we are. It enfolds us each and joins us together in a supremely respectful embrace which is deeper than any word. It is a gift we offer one another. Custody of the eyes serves similarly and seems to me to be a piece of the monastic and eremitical values of stricter separation from the world and the silence of solitude especially. It too is ordered toward loving others and providing the gifts of space and privacy in which they may seek and commune with God while at the same time making sure they are profoundly supported in this.
