Hi, my son is 3 y 5 months old. His left eye is little sensitive. It gets watery very easily whenever he goes is bright light, heavy wind or during cold, or if something goes in eye. Also greenish whitish substance comes from eye similar to what we see in conjunctive eyes. We consulted an eye specialist but per his it was general eye infection and gave toba-f drops for same. This condition of eye is not regular or continues but more frequent. This never happened to his right eye. Please guide.
