There are two possibilities:
1. Allergic conjunctivitis
- you can try eye drops like Olopatadine
2 drops/eye upto three times daily for 5 days and see the difference.
2. Nasolacrimal duct
blockage - the connection between the eyes and draining sinuses, but is usually in younger children
If Olopatadine does not work, see an Opthalmologist.
If there are other symptoms such as sneezing
, red eyes then allergic rhinitis/rhinoconjunctivitis is a possibility and Olopatadine will help.
