For many people with dry or sensitive eyes, understanding the ingredients in eye drops is crucial for preventing irritation and discomfort. One of the most important differentiators is the presence of preservatives, and for the popular brand REFRESH Optive, the answer to this question is not a simple 'yes' or 'no.' It depends entirely on the product's packaging.
The Preserved Multi-Dose REFRESH Optive
When you purchase REFRESH Optive in a standard multi-dose bottle, it contains a gentle, but active, preservative to maintain its sterility after the bottle is opened. The specific preservative used in this formulation is called PURITE® (stabilized oxychloro complex).
How PURITE works
Unlike some older, harsher preservatives like benzalkonium chloride (BAK), which can be toxic to the delicate surface cells of the eye over time, PURITE is designed to be gentler. When exposed to the ultraviolet light on the surface of the eye, PURITE breaks down into harmless components, including water and salt. This process effectively kills any bacteria that may have contaminated the tip of the bottle but minimizes prolonged exposure of the eye's surface to the preservative itself. For individuals with mild, occasional dry eye who don't require drops frequently, a preserved formula may be a convenient and cost-effective option.
The Preservative-Free REFRESH Optive
For individuals with more severe dry eye, sensitive eyes, or those who use eye drops frequently throughout the day, the preservative-free option is the recommended choice. REFRESH Optive Preservative-Free is sold in individual, sterile, single-use vials that are discarded after each use.
The benefits of preservative-free drops
There are several reasons why a person might opt for a preservative-free eye drop:
- Minimizes irritation: Constant or frequent exposure to preservatives can cause irritation, redness, and inflammation of the eye's surface. Preservative-free drops eliminate this risk, making them suitable for sensitive eyes.
- Safe for frequent use: Patients who need to apply artificial tears more than four times a day are often advised to use a preservative-free formula to prevent cumulative preservative toxicity.
- Post-surgical care: Eye doctors often recommend preservative-free drops for patients recovering from eye surgery, such as LASIK, to soothe dryness without interfering with the healing process.
- Reduces allergic reactions: Some individuals can develop allergies to certain preservatives, leading to uncomfortable symptoms. Preservative-free drops remove this potential allergen.
New Innovations in Preservative-Free Packaging
In recent years, advancements in packaging technology have allowed for the development of multi-dose preservative-free bottles. These innovative bottles use a one-way valve or specialized filtration system to maintain the sterility of the contents without the need for preservatives. Brands like REFRESH have started releasing products using this technology, offering the convenience of a multi-dose bottle with the benefits of a preservative-free formula. Examples include newer REFRESH RELIEVA PF multi-dose products.
Choosing the Right Formula for Your Needs
Deciding between preserved and preservative-free drops depends on your individual needs and eye sensitivity. While preserved drops are sufficient for occasional use and non-sensitive eyes, the single-use vials are the safer, more gentle option for frequent users or those with chronic dry eye. Consulting with an eye care professional is always recommended to determine the best course of action.

Conclusion
In summary, the answer to the question, 'Does REFRESH Optive have preservatives in it?' is yes and no. The multi-dose bottle contains the gentle preservative PURITE, which keeps the product sterile for safe, occasional use. However, the sterile single-use vials are explicitly preservative-free and are the best option for sensitive eyes, frequent use, or post-surgical care. When shopping for REFRESH Optive, always check the packaging to confirm you are selecting the right formula for your specific needs.
It is important to remember that using a product that contains preservatives too frequently can lead to ocular surface damage and increased irritation, especially for those with moderate to severe dry eye. If you are unsure which formula is right for you, or if your dry eye symptoms persist, it is best to consult with an eye doctor for a personalized recommendation.
