After Titania falls in love with a transformed Bottom due to the love potion's effect, Oberon observes Demetrius rejecting Helena's affections and expresses displeasure at this unrequited love. To rectify the situation, Oberon decides to use the love potion, not on Demetrius directly, but rather on Demetrius' eyes so that he will see "true Ovid's feature" n Helena's face upon gazing at her. Once the love potion is dripped into Demetrius' eyes while he sleeps, Demetrius' transformation happens off-stage and is not explicitly spoken out by the character himself.
