Refresh Optive (30 PF vials)

About Refresh Optive Active ingredients: Carboxymethylcellulose, glycerin Preservative-free Box of 30 0.01 fl oz/ 0.4mL vials Description (by Rebecca) When Optive first came out, it was Allergan's first drop using glycerin - but in conjunction with carboxymethycellulose which is a common polymer for artificial tears. It's a nice balance of a drop - not so watery-feeling that you feel drier five minutes later, but not so goopy that you can't see clearly for ten minutes either. It proved quite popular and has developed into a strong brand-within-a-brand. They now have two spin-offs of it - "Advanced", which has just slightly more glycerin and also adds polysorbate 80, and now "MEGA-3" which is the same as Advanced plus castor oil and flaxseed oil. Description (from the manufacturer's literature) REFRESH OPTIVE® contains not just one, but two active ingredients that help relieve dry, burning, irritated eyes due to Dry Eye. This specially designed, preservative-free formula provides long-lasting moisture that hydrates and protects the cells of the eye that can become damaged due to Dry Eye. And, since REFRESH OPTIVE® is preservative-free, it is gentle enough for sensitive eyes. It is also recommended for post-LASIK dryness. If you have recently had LASIK surgery, please follow your eye doctor’s instructions regarding the use of REFRESH OPTIVE® Preservative-Free. REFRESH OPTIVE® Preservative-Free Lubricant Eye Drops come in sterile, single-use vials you can take with you anywhere. They are safe to use as often as needed.  Drug Facts (from manufacturer's site): Active Ingredients / Purpose Carboxymethylcellulose Sodium (0.5%) / Eye Lubricant Glycerin (0.9%) / Eye Lubricant Uses For the temporary relief of burning, irritation, and discomfort due to dryness of the eye or exposure to wind or sun.  May be used as a protectant against further irritation.
