If you want a preservative-free multi-dose bottle instead, **Biotrue Hydration Boost for Contacts** is the pick, in a smaller 0.33 fl oz size with a claimed 8-hour moisture window. The five drops below all say they can go in while your contacts stay in, but the bottle size, the ingredient list and the lens types they cover are different enough to matter. In this guide 1.

Bottle size does matter, but it is not what decides the purchase. Lens compatibility is. Two of the five bottles here name the lens types they are cleared for. Refresh Contacts says it lubricates and rewets soft lenses **and** rigid gas permeable ones, including silicone acrylate and fluorosilicone acrylate materials. Opti-Free Puremoist says it is for all silicone hydrogel and other soft lenses. Renu says extended-wear, frequent-replacement and disposable soft lenses. Biotrue and Refresh Relieva say "contact lenses" without narrowing further on the listing text. If you wear RGP lenses, that narrows this list to one. If you wear silicone hydrogels, three are explicitly named for that job. The ingredient list is the tie-breaker after that: hyaluronic acid, preservative-free, and any specific irritants you have reacted to before. None of the drops here list an active pharmaceutical for red eye or allergy. These are lubricants and rewetters, and they are not a substitute for a redness reliever, an allergy drop, or a prescription treatment for dry eye disease. Check with your eye care professional before switching if you are treating a diagnosed condition. ## How I screened the shortlist I lined up the specifications side by side across every rewetting drop bottle listed in this category and read what each manufacturer actually claims on the Amazon listing. That gave me five criteria I could compare directly. 1. **Named lens compatibility.** Does the listing tell you which lens types are safe? 2. **Bottle size in fl oz or mL**, because that is what determines how long a bottle lasts. 3. **Ingredient disclosure**, especially hyaluronic acid, glycerin, or a preservative-free claim. 4. **Application method**, meaning whether the drops can be used with lenses in the eye. 5. **Bottle dimensions**, because a rewetter you cannot carry is a rewetter you forget. Anything that failed to name a lens compatibility category was ranked below anything that did. Anything without a size on the listing was cut. The five picks that survived all confirm on the listing that you can keep contacts in during application, which is the whole point of a rewetting drop rather than an artificial tear. ## 1\. Refresh Contacts Contact Lens Comfort Drops — Best overall **The one bottle in the set that names both soft and rigid gas permeable lenses as compatible, at the smallest price position in the group.** [![Refresh Contacts 12 mL blue-labelled rewetting drops bottle — the only pick here cleared by the manufacturer for RGP lenses](https://m.media-amazon.com/images/I/51mwyf6Q-4L._SL500_.jpg)](https://www.amazon.com/dp/B0000537AJ?tag=tispan-20) **Best for:** wearers who want one bottle that covers soft and rigid gas permeable lenses **Skip it if:** you specifically want a preservative-free formula Refresh Contacts is a 0.4 fl oz (12 mL) bottle at the cheapest price position of the five, and the specification that sets it apart is right there in the listing text: it is cleared for soft lenses and for silicone acrylate and fluorosilicone acrylate rigid gas permeable lenses. Nothing else in the group makes that RGP claim. The bottle is 3.6 x 1.15 x 1.8 in and 11.3 g, so it fits a coat pocket without being the thinnest option here. Refresh says the drops cushion lenses before insertion as well as rewet them in-eye, which is a use case the other listings do not describe in the same words. The formula is listed as original strength rather than preservative-free, and if a preservative-free multi-dose bottle is a firm requirement, Biotrue is the pick further down. The trade-off against a newer formula like Biotrue is ingredient disclosure. Refresh names its role and its lens compatibility, but does not spell out hyaluronic acid, electrolyte and antioxidant the way Biotrue does. **Pros:** - Only pick here cleared for RGP lenses (claim) - Full 0.4 fl oz (12 mL) bottle - Cheapest of the five - Sells faster than the rest of this set - Can be used with contacts in place **Cons:** - Not a preservative-free formula - Ingredient list less detailed than newer picks - 2005 listing, older than the Biotrue and Renu bottles [Check Price on Amazon](https://www.amazon.com/dp/B0000537AJ?tag=tispan-20) ## 2\. Opti-Free Puremoist Contact Lens Rewetting Drops — Best for beginners **A 12 mL silicone hydrogel-focused bottle that Opti-Free says also rinses irritating particles from the lens surface.** [![Opti-Free Puremoist 12 mL rewetting drops in white bottle — the silicone hydrogel pick with a particle-rinse claim](https://m.media-amazon.com/images/I/41Mi6+06qVL._SL500_.jpg)](https://www.amazon.com/dp/B005JRDYKC?tag=tispan-20) **Best for:** new silicone hydrogel wearers who also want particle rinsing **Skip it if:** you wear rigid gas permeable lenses Opti-Free Puremoist matches Refresh Contacts on bottle size, 0.4 fl oz (12 mL), and sits in the middle of the price positions here. Alcon writes the listing around silicone hydrogel and other soft lenses, which is the category most modern monthly and two-week lenses fall into. Two claims in the listing set it apart from the rest of this group: Opti-Free says the drops remove particles that cause irritation and help prevent deposit build-up. Renu makes a lubrication and moisture claim, and Biotrue mentions deposit buildup too, but the particle-rinse language is Opti-Free's own. If you regularly get a stray eyelash fibre or a fleck of makeup trapped under a lens, that framing is useful. Bottle dimensions are 3.88 x 1.25 x 1.75 in and 13.6 g, the heaviest bottle in the set. The trade-off is lens type. If your prescription is for RGP lenses, this is not the right pick and Refresh Contacts is. Beginners on their first pair of silicone hydrogels will find the listing language matches what their optometrist likely said. **Pros:** - Full 0.4 fl oz (12 mL) bottle - Named for all silicone hydrogel and soft lenses (claim) - Particle-rinse claim not made by other picks - Mid price position in this set **Cons:** - No RGP claim on the listing - Heaviest bottle at 13.6 g - Not marketed as preservative-free [Check Price on Amazon](https://www.amazon.com/dp/B005JRDYKC?tag=tispan-20) ## 3\. Biotrue Hydration Boost for Contacts — Best for heavy use **The only preservative-free multi-dose bottle in the group, with a claimed 8-hour moisture window per application.** [![Biotrue Hydration Boost 0.33 fl oz bottle in blue and orange trade dress — the preservative-free multi-dose pick](https://m.media-amazon.com/images/I/417-21ov+xL._SL500_.jpg)](https://www.amazon.com/dp/B0BW1V33K8?tag=tispan-20) **Best for:** long screen days when you reach for drops every couple of hours **Skip it if:** you want the cheapest bottle in this set Biotrue is a 0.33 fl oz bottle, smaller than the two 12 mL bottles above it but bigger than the two 0.27 fl oz picks. Bausch + Lomb writes it up as the first preservative-free multi-dose contact lens drops, which is the standout claim in this shortlist. If you have reacted to preservatives before, that alone narrows five picks to one. The listing names hyaluronan (HA), an antioxidant that Biotrue says protects the HA from free radicals, and an electrolyte. It also claims up to 8 hours of moisture per application, attributed to a laboratory study Bausch + Lomb does not publish in the listing. Take the number as a manufacturer claim rather than a verified reading, and treat it as a reason to reach for the bottle less often on a long day rather than a promise. The trade-off against Refresh Contacts is two-fold: Biotrue sits in the premium price band of this set, and the bottle does not name RGP lenses. **Pros:** - Preservative-free multi-dose formula (claim) - Hyaluronan, antioxidant and electrolyte listed - 8-hour moisture claim (manufacturer) - pH balanced (claim) **Cons:** - Premium price position of the five - Smaller than the 12 mL bottles at 0.33 fl oz - No RGP compatibility claim [Check Price on Amazon](https://www.amazon.com/dp/B0BW1V33K8?tag=tispan-20) ## 4\. Renu Lubricant Rewetting Eye Drops for Contact Lenses — Best compact **The smallest bottle in the group at 2.95 x 1.57 x 0.98 in and 7.65 g, aimed at extended-wear and disposable soft lens users.** [![Renu 0.27 fl oz compact rewetting drops bottle — the smallest carry-friendly bottle in the shortlist](https://m.media-amazon.com/images/I/51hH99XvFvL._SL500_.jpg)](https://www.amazon.com/dp/B00078XIPE?tag=tispan-20) **Best for:** throwing in a jeans pocket or a small handbag **Skip it if:** you prefer a larger bottle that lasts longer between refills Renu's rewetter is 0.27 fl oz and, at 2.95 x 1.57 x 0.98 in and 7.65 g, it is the shortest and lightest bottle in this comparison. Bausch + Lomb writes the listing around extended wear, frequent replacement and disposable soft lenses, which are the categories daily-lens and biweekly-lens wearers will recognise. The listing describes the fluid as soothing, moisturising and refreshing to lenses, and says it helps relieve dryness and irritation caused by contact lens wear. It sits in the second-cheapest price position, above Refresh Contacts and below the three mid and premium bottles. What Renu does not do is name specific ingredients on the listing the way Biotrue does, or claim compatibility with RGP lenses the way Refresh Contacts does. The trade-off is straightforward. You pay for portability with volume: 0.27 fl oz is roughly two-thirds of a 12 mL bottle, so it runs out sooner if you use drops several times a day. **Pros:** - Smallest footprint in the set (2.95 x 1.57 x 0.98 in) - Lightest bottle at 7.65 g - Second-cheapest price position - Named for extended-wear and disposable soft lenses (claim) **Cons:** - Slowest seller of the five - Only 0.27 fl oz per bottle - No named ingredients on the listing [Check Price on Amazon](https://www.amazon.com/dp/B00078XIPE?tag=tispan-20) ## 5\. Refresh Relieva for Contacts Lubricant Eye Drops — Best premium **A 0.27 fl oz (8 mL) formula Refresh describes as scientifically designed for contact lens wearers, with carboxymethylcellulose, glycerin and hyaluronic acid listed.** [![Refresh Relieva for Contacts 8 mL clear bottle — the premium pick with CMC, glycerin and hyaluronic acid](https://m.media-amazon.com/images/I/41t+avDOF4L._SL500_.jpg)](https://www.amazon.com/dp/B07XC95XP2?tag=tispan-20) **Best for:** burning, irritated eyes at the end of a long lens-wearing day **Skip it if:** your dryness is mild and occasional Refresh Relieva sits at the top of the price positions here, in an 0.27 fl oz (8 mL) bottle measuring 3.5 x 1.13 x 1.75 in. The listing calls out four named components: carboxymethylcellulose (CMC), glycerin, hyaluronic acid as an inactive ingredient, and what Refresh calls HydroCell technology. That is the most detailed active-and-inactive ingredient disclosure of the five picks. Refresh writes the listing around burning and irritation as much as dryness, which is a slightly different emphasis to the plain rewetter framing that the other four bottles use. The company says it is safe to use as often as needed and as a contact lens rewetter, and that contacts can stay in during application. The listing does not narrow lens compatibility to soft, silicone hydrogel or RGP the way the Refresh Contacts and Opti-Free bottles do. The trade-off against Refresh Contacts is size and price. You get a smaller bottle in a higher price band, in exchange for a more detailed ingredient list. **Pros:** - Carboxymethylcellulose, glycerin and HA on the listing - Aimed at burning and irritation, not just dryness (claim) - Refresh HydroCell technology (claim) - Safe to use as often as needed (claim) **Cons:** - Highest price position of the five - 0.27 fl oz, smaller than the 12 mL bottles - No specific lens-type claim on the listing [Check Price on Amazon](https://www.amazon.com/dp/B07XC95XP2?tag=tispan-20) ## Soft, silicone hydrogel or RGP: which drops match your lenses? The listing text for each bottle uses one of three lens vocabularies, and the vocabulary tells you what the manufacturer has designed the formula around. - **Soft lenses**, meaning traditional hydrogel lenses. All five picks are described as safe with soft lenses. - **Silicone hydrogel lenses**, the modern high-oxygen material used in most monthly and two-week lenses today. Opti-Free Puremoist names this category directly. - **Rigid gas permeable (RGP) lenses**, harder lenses that stay in shape on the eye. Refresh Contacts is the only bottle here that names silicone acrylate and fluorosilicone acrylate RGP materials as suitable. If you do not know which category your lenses fall into, the box they came in will say. If it says "silicone hydrogel" or a brand name like Acuvue Oasys or Biofinity, you are in the middle category. If your optometrist fitted hard lenses that go in a hard case with two chambers, you are in the RGP category and Refresh Contacts is the safer default. ## How long does a bottle of rewetting drops actually last? The bottles here split cleanly into two sizes: 12 mL for Refresh Contacts and Opti-Free Puremoist, and 8 mL (or the equivalent 0.27 fl oz) for Renu and Refresh Relieva, with Biotrue slotting between at 0.33 fl oz. That difference matters more than it looks. A rewetting drop bottle typically dispenses around 20 drops per mL, which means a 12 mL bottle carries in the region of 240 drops and an 8 mL bottle carries roughly 160\. Use one drop per eye, twice a day, and a 12 mL bottle lasts around two months, while an 8 mL bottle lasts closer to six weeks. Use drops every couple of hours through a long screen day and both bottles come down to a matter of weeks. Two practical takeaways. First, if you know you use drops heavily, size up: the 12 mL Refresh Contacts and Opti-Free bottles cost less per drop than the smaller premium bottles. Second, once a preservative-free bottle like Biotrue is opened, the manufacturer's on-pack instructions tell you how long it stays safe to use, and that window is usually shorter than a preserved formula. Read the outer carton before you buy multiple bottles. ## What the listings do not tell you A rewetting drop listing on Amazon gives you the bottle size, the lens compatibility claim, the ingredients the brand chooses to highlight, and the marketing angle. What it does not give you is straightforward. - **Preservative names.** Biotrue is called preservative-free, and the others are not called preservative-free, but the specific preservative used by each preserved formula is not on the listing. - **Osmolarity and pH.** Only Biotrue mentions pH balance in the listing. - **Full inactive ingredient list.** Refresh Relieva lists CMC, glycerin and HA; the other four do not itemise like that. - **How the drops interact with a specific lens brand.** Compatibility is described by category, not by brand. If any of those details are non-negotiable for you, take the specific formula name to your eye care professional before you buy, or read the outer carton once the bottle arrives. ## Head-to-head: Refresh Contacts vs Biotrue Hydration Boost These are the two picks most readers will genuinely deliberate between: the cheap 12 mL all-lens bottle and the premium 0.33 fl oz preservative-free one. Refresh Contacts wins on three fronts. It costs less per bottle, it holds more fluid at 12 mL versus 0.33 fl oz, and it is the only bottle in the shortlist that names RGP lenses on the listing. It is a 2005 formula, so it is well-established and widely stocked. Biotrue wins on ingredient disclosure and preservative status. Bausch + Lomb writes it up as preservative-free multi-dose, adds hyaluronan, an antioxidant and an electrolyte, and claims up to 8 hours of moisture per application. If you have ever had to switch drops because a preservative irritated you, that is the tie-breaker. Cutoff: if you wear RGP lenses, or you use drops so heavily that bottle size dominates, Refresh Contacts is the right default. If you wear soft or silicone hydrogel lenses and preservative sensitivity is a real concern, Biotrue is the buy. ## The verdict Refresh Contacts Comfort Drops is the best rewetting eye drops for contacts choice as a default, because it is the only bottle in this shortlist that names both soft lenses and rigid gas permeable materials as compatible, it is the 12 mL size that lasts longest between refills, and it sits at the cheapest price position of the five. That combination is unusual: bigger bottles usually cost more, and broader compatibility usually costs more. Here it does not. Two conditions flip the pick. The first is preservative sensitivity: if you have reacted to a preserved rewetting drop before, Biotrue Hydration Boost is the buy because it is the only preservative-free multi-dose bottle in the group. The second is silicone hydrogel wear combined with regular particle irritation from lashes, dust or makeup: Opti-Free Puremoist is written around that use case in a way Refresh Contacts is not. Everything else in the set fills a narrower role. Renu is the small-bottle pocket pick. Refresh Relieva is the ingredient-disclosure pick for people whose eyes burn as much as they feel dry. ## FAQ ### Are rewetting eye drops for contacts different from regular artificial tears? Rewetting eye drops for contacts differ from most regular artificial tears in one respect: the listings for all five picks here confirm the bottle can be used while contacts stay in the eye. Many general artificial tears warn against use with lenses in place. Always read the specific bottle's instructions, because ingredient formulas vary and a drop safe with one lens type is not automatically safe with another. ### Is a preservative-free bottle worth paying more for? A preservative-free bottle is worth the premium if you have ever reacted to a preserved drop, if you use rewetters several times a day, or if your eye care professional has recommended one for a specific reason. Biotrue Hydration Boost is the only bottle in this shortlist marketed as preservative-free multi-dose. For occasional users with no sensitivity history, a preserved 12 mL bottle like Refresh Contacts costs less per drop. ### Can I use these drops with rigid gas permeable lenses? Using these drops with rigid gas permeable lenses is only clearly supported by one bottle in this set. Refresh Contacts names silicone acrylate and fluorosilicone acrylate RGP lenses in the listing as compatible. The Opti-Free bottle names silicone hydrogel and soft lenses, and Renu names extended-wear and disposable soft lenses. If you wear RGP lenses, Refresh Contacts is the safer default here. ### Refresh Contacts vs Opti-Free Puremoist: which should I pick? Refresh Contacts vs Opti-Free Puremoist comes down to lens material. Both are 0.4 fl oz (12 mL) bottles. Refresh names soft and RGP lenses on the listing, and sits at the cheapest price position in this set. Opti-Free names silicone hydrogel and soft lenses, sits in the middle price position, and adds a particle-rinse claim. Silicone hydrogel wearers lean Opti-Free; mixed or RGP wearers lean Refresh. ### What is the biggest mistake people make with rewetting drops? The biggest mistake with rewetting drops is treating them as a fix for a symptom that needs a different product. Rewetters are lubricants, and none of the five bottles here treat redness, allergy or diagnosed dry eye disease. If your eyes are red for hours, watery all day or painful, book an eye exam rather than reaching for another bottle. Rewetters address lens-related dryness only. Two next steps make sense from here. Check the box or blister pack your contacts came in for the material name, then match it against the five bottles above. Soft or silicone hydrogel wearers with no preservative history can order Refresh Contacts as the default. RGP wearers should also order Refresh Contacts, because it is the only bottle here that specifically names their lens materials. Anyone reaching for drops several times a day, or with a preservative sensitivity, should order Biotrue Hydration Boost instead. A 12 mL bottle at the cheapest price position with the broadest lens compatibility is a hard combination to beat as a starting point. *Last updated: September 30, 2026\.
