Tears Plus Eye Drop contains Povidone and Polyvinyl Alcohol. 
Polyvinyl alcohol is used to increase the viscosity and thereby prolonging contact time of the Povidone within the eye.
Povidone (polyvinylpyrrolidone) helps to retain the tears on the cornea longer. It acts as artificial tears to help ease dryness and soreness associated with dry eye conditions.
 
Tears Plus Eye Drop is beneficial for the symptomatic treatment of dry eye conditions. Eye drop is also suitable for comforting irritated, dry and tired eyes and is also effective in-eye re-wetting of contact lenses.
