TheraTears Lubricant Eye Drops are indicated for mild to moderate dryness of the eyes. They contain a patented preserving ingredient that turns into pure oxygen and water on eye contact. Oxygen and water work with the TheraTears formula to provide soothing dry eye relief that works, without the irritation that sometimes results from other artificial tears with harsher preservatives.
Retaine MGD is a preservative-free ophthalmic emulsion that moisturizes, lubricates and protects moderate to severe dry eyes. Unlike other lubricant eye drops which can evaporate quickly, Retaine MGD provides long-lasting relief utilizing Novasorb, a proprietary cationic oil emulsion technology that effectively delivers ingredients through electrostatic attraction between positively charged droplets and the negatively charged ocular surface. The hypotonicity of the emulsion adds moisture by lowering the salt concentration of tears while the lipid component lubricates and protects the surface of the eye.
