Ring of Birdseye Maple

Ring, uncommon (optional attunement)
  Pale green, eye-like tourmalines have been encapsulated in maple roots sung by seelie fey into pleasing knots and braids.
  This ring has 5 charges, and regains 1d4 + 1 expended charges daily at dawn. While wearing the ring, whenever you touch a plant or surface made of wood, you can expend 1 charge to cause an eye to grow anywhere along that plant/surface within 60 feet of you. You can see out of the eye, which has darkvision out to 60 feet, for as long as you remain touching the plant/surface. While you look out of the eye, you are blinded with regards to your own senses.
  The eye has a Dexterity (Stealth) modifier of + 8. It has AC 10 and 5 hit points. Any damage dealt to the eye is transferred back to you as psychic damage.
  Optional Attunement. While you are attuned to the ring, it gains the Eyesoar property.
  Eyesoar. If you stop touching the wood in which you have grown an eye, the eye persists for one hour or until you create a new eye. So long as the eye is within 150 feet of you, you can use an action to look through the eye. While looking through the eye you can, as an action, move the eye up to 30 feet along the wood.
