What causes a sandy feeling in the eye?
may be a combination of allergies and dry eye
HI, thanks for using healthcare magic
Dry eyes is a common cause of XXXXXXX sensations in the eye.
It can also occur as a result of allergies or infection. Infection is not likely because it would not persist for 2 months without causing a lot of symptoms.
Allergies normally involve both eyes but can, in some persons, involve only one eye.
Some persons may have more than one reason for the XXXXXXX feeling in the eye eg allergies and dry eye.
You may want to consider continuing the lubricants for dry eye, increasing the amount used (most lubricants can be used as needed but you can check ) and add an allergy drop to treat allergy symptoms as well.
Eg of allergy eye drops are pataday, emandine, livostin, optivar
These may require a prescription from your doctor
I hope this helps, feel free to ask any other questions
