Ring of the Shining Eye

Dark Sight. This ring holds 6 charges and regains 1d6 charges at midnight. You can use a bonus action to speak a command word and expend 2 charges. When you do, you gain Darkvision out to 120ft. for one hour.   Night Blind. You may use an action to expend 4 charges by pointing to a creature you can see within 120ft. of you and whispering a command word. The creature has to make a Wisdom saving throw. The DC for this saving throw is equal to your Passive Perception or your spell save DC, whichever is higher. On a failed save, the creature becomes Cursed for 1 hour. While Cursed in this way, they lose their Darkvision and cannot benefit from any spells or effects that would give them Darkvision.
