I always feel something like smoke in my eye,it will not allow me to open my eye very well and i can't be able to use it to read for longtime, it started since i start working in balm producing company but because of that i stop the work last month?

Sounds like you need to have your eyes examined by an eye doctor.

You likely had a chemical conjunctivitis and/or keratitis secondary to exposure to the chemicals in the balm producing company that you work in. You should be examined by an ophthalmologist to make sure there is no ongoing damage or treatment required. Moving forward, it is important to make sure that the workplace is well ventilated and that you wear eye protection and a ventilator.

If it is environmental irritation, it should improve over time away from work exposure. You may wish to see a physician for a full workup
