My son turned 2 this May and since last 6 months he has tears (a drop or 3) in his left eye alone at particular instances which include exposure to air or wind, when watching tv or after taking head bath or whenever we go for a walk. We moved to Scotland in November 2019 and this issue started from day 1. The weather was very cold till February 2020 and from March 2020 until now it's pleasant. We consulted doctors here and they said unless he has reddish eyes or irritation(which he doesn't have), there isn't any problem and that it should be due to the change of weather. He doesn't allow doctors to check his eyes as he raises a ruckus everytime we visit the doc and we are helpless including the doc. Kindly advise. Please.
