Blindness Medicine is an item in Spyro: Shadow Legacy, used to cure blindness. It was created by mixing Pine Needles, Sulfur Powder and Mercury.
Akello used this medicine to cure his blindness due to being old. When the Shadow Realm weakened his eyesight, he was out of this medicine, causing Adama to make him a new one and tasked Spyro with finding the ingredients needed.
When Akello drank it and regained eyesight, he read a letter from his son, Hunter.
