How Tears Guard is Different?

Tears guard is an artificial tears preserved with a disappearing preservative (sodium perborate ) which is  converted into pure water and oxygen when in contact with the eye tissues by anti oxidant enzymes ( catalase , superoxide dismutase , Glutathione peroxidase ) .
Because patients with dry eye may be more susceptible to preservative toxicity; such patients may not produce sufficient tears to dilute a harmful preservative. Any patient who uses multiple preserved drugs increases the concentration of preservatives on the ocular surface. High concentrations of preservatives or repeated exposure to   preservatives increase the chances of adverse effects.

With the disappearing preservative:

• No more ocular tissue toxicity
• No fear of preservative allergy
• No effect on tear lipid layer
• No irritation or burning sensation
