How safe is Itone Eye Drop for regular use. I use laptop approx 12 -14 hours, I have near spherical 2.0 on both eyes. My age is 50. I am using ITONE eye drops regularly (bedtime and morning) or as and when my eyes feel tired. Is ITONE safe? Most allopathic eye specialists criticize it, saying it is ayurvedic and there is no quality control, Instead asking me to use EYEMIST FORTE or REFRESH TEARS. I want opinion on how safe this is. I have got my eyes checked and apart from reading number (common at my age), my eyes are perfectly OK.
