Clear sight is the ability to see through the Mist, the force that hides the truth from most mortals. Some mortals are born with this gift. All demigods have this ability to some extent, but can be tricked.
When Percy Jackson is at the Hoover Dam, he slashes at Rachel Elizabeth Dare, who sees Riptide for what it is. She shows that she can see through the Mist by seeing the skeleton warriors for what they are and directing them away from Percy. Thalia Grace then explains it to Percy. Dr. Chase was also able to see through the Mist. An example of this is when he talked about the pegasi's wingspan compensating for the weight of the horse.
A young girl is able to see Ares' War Chariot in its true form, but her mother can not.
Rachel continues to help Percy. Sally Jackson wakes up from her sleep and is able to see the monsters and gods fighting each other in the Battle of Manhattan.
Amir Fadlan gains this ability by opening his mind to the possibility that their is more to the universe.
- Sally Jackson
- Rachel Elizabeth Dare
- Maria di Angelo
- May Castellan
- Marie Levesque
- Frederick Chase
- Amir Fadlan
- All demigods and legacies (to a certain degree, as the Mist has been shown to repeatedly fool even the most experienced demigods).
- Some mortal children can see through the Mist, as they are more open minded.
- It is mentioned that not even the gods understand why some humans are born with the ability to see through the Mist.
- It is believed that children can see through the Mist because they are more open minded. However, most lose this ability as they get older.
- Frederick Chase and Amir Fadlan are the only known clear sighted humans who are male.
- Sally Jackson mentioned that she cannot see through the Mist as well as she did when she was younger, suggesting that clear sight declines with age. 
- Amir Fadlan is the only known human to gain the ability, as all other known users are born with it. This shows that it is possible to gain the ability as well.
