Multiple causes: There are many causes of burning sensation in the eyes in the absence of infection. Most common causes are allergy, irritation from dust or foreign body, and dry eyes (not enough tears).

Dry eyes likely: The plica semilunaris is a vestigial structure of the nictitating membrane seen in other animals. It aides in forming a tear lake. The burning sensation you are experiencing is likely dry eye related and artificial tears should aid in your comfort.
