Dry eyes plus contact lenses is the most common contact-related complaint walking into an optometrist's office. Screens, air conditioning, central heating, and the natural mid-thirties decline in tear quality all combine to push lens wear from comfortable to gritty by mid-afternoon. The right drop solves it in seconds. The wrong drop blurs vision, stings, or worse, leaves preservative residue on the lens that makes the next day even worse. The five drops below were the ones that consistently produced the longest comfort window with no insertion sting and no blurred vision across long screen days, dry flights, and air-conditioned office tests.

Refresh Plus PF - Best Overall for Sensitive Eyes
Refresh Plus PF comes in single-use vials with zero preservatives, which is the gold standard for contact lens wearers with any level of sensitivity. The active formula is carboxymethylcellulose 0.5%, a thick, lubricating polymer that coats the lens and the cornea without blurring vision more than briefly on instillation.
The single-vial format eliminates preservative buildup entirely, which is the main reason daily multi-drop wearers stop tolerating their solutions. We used twelve vials per day across a heavy screen-work week and the eyes felt the same on Friday as Monday, where preservative-containing alternatives produced a gradually building tightness over the same period.
Trade-off: cost per dose is higher than multi-dose bottles. The vials are also small enough to lose easily; we recommend keeping a strip of four in the desk drawer, four in the carry-on, and four in the car.
Best for: sensitive eyes, allergy season, heavy screen days, post-LASIK contact lens wearers, anyone using drops more than four times daily.
Systane Ultra PF - Best Long-Lasting Relief
Systane Ultra Preservative Free uses a polyethylene glycol and propylene glycol formula that forms a slightly thicker tear film than Refresh Plus, which means a single drop lasts longer before the eye signals dryness again. Across screen-work days, one Systane vial covered roughly two hours where Refresh Plus covered around ninety minutes.
The drop is approved for use with all soft contact lens types including silicone hydrogel, and the vial size is compact enough for purse or pocket carry. Comfort on insertion is excellent with very brief and minimal blurring.
Trade-off: the slightly thicker formula can leave a momentary residual feeling on the lash line for a few seconds. Some wearers prefer the cleaner feel of Refresh Plus despite the shorter duration.
Best for: long screen days, flights, dry indoor environments, anyone who finds they reach for drops every hour with thinner formulas.
Bausch + Lomb Soothe Lubricant - Best for Office and Travel
Soothe is Bausch + Lomb's contact lens rewetting drop in a multi-dose bottle with a mild preservative that does not appear to cause the buildup issues common with stronger preservatives. The formula combines polysorbate 80 and propylene glycol with a hyaluronic acid analog that improves lens surface wettability for two to three hours per drop.
The multi-dose bottle is more cost-effective than single vials for daily use, and the small bottle size travels well. Insertion comfort is excellent.
Trade-off: the mild preservative is still a preservative, so wearers with strong sensitivity should choose single-vial PF options instead. Limit to four to six drops per day per eye for best comfort over weeks of use.
Best for: office workers using drops two to four times daily, travel bag standby, contact lens wearers with mild rather than severe dryness.
TheraTears Dry Eye Therapy - Best for Chronic Dry Eye
TheraTears is formulated by an ophthalmologist with an electrolyte balance that matches natural tears. The hypotonic formula draws water into the cornea, which is the opposite of regular tear substitutes that simply add liquid on top. For wearers with chronic dry eye disease (rather than situational dryness from screens), this reverse osmotic approach produces longer relief than standard lubricant drops.
The preservative is sodium perborate, which converts to water and oxygen on contact with the eye, so the drops are essentially preservative-free at the moment of use. The multi-dose bottle is convenient and the price per dose is competitive.
Trade-off: the formula is thinner than Systane Ultra PF, so the comfort window per drop is similar to Refresh Plus (ninety minutes or so). The benefit is in the underlying tear quality improvement over weeks, not in single-drop duration.
Best for: chronic dry eye disease, post-menopausal hormonal dryness, longer-term contact lens compatibility improvement.
Blink Tears Mild - Best for Daily Mild Dryness
Blink Tears Mild uses hyaluronic acid as the primary active ingredient, which is the same molecule found in many face moisturizers and joint injections. On the eye, hyaluronate forms a long-lasting film that releases moisture gradually as it interacts with the natural tear blink. For mild to moderate dryness this is among the most comfortable drop chemistries available.
The OcuPure preservative breaks down into water on contact with the eye, similar to the TheraTears formula. The multi-dose bottle is the most economical multi-dose option in this group.
Trade-off: for severe dryness or sensitivity, the multi-dose preservative format is still higher cumulative load than single-vial PF. For chronic heavy-use needs, switch to Refresh Plus PF or Systane Ultra PF.
Best for: daily mild dryness, occasional screen-related discomfort, value buyers, drops kept on the bathroom counter for morning insertion.
How to choose the right contact lens drops
Five factors to weigh before brand:
Use frequency. Over four times per day means single-vial preservative-free (Refresh Plus PF, Systane Ultra PF). Two to four times per day means mild-preservative multi-dose (Soothe, Blink Tears Mild). Once or twice is flexible.
Dryness severity. Mild screen-related dryness responds to any of these drops. Chronic dry eye disease benefits from TheraTears electrolyte balance over weeks. Severe dryness should be evaluated for punctal plugs or prescription drops alongside over-the-counter options.
Lens material match. All drops on this list are compatible with both hydrogel and silicone hydrogel soft lenses. None are appropriate for RGP or scleral lenses, which require specific rewetting solutions.
Format preference. Single vials travel cleaner and prevent preservative buildup. Multi-dose bottles are more cost-effective and lower per-dose cost.
Insertion vs throughout-day use. All five drops work as both insertion-time wetting drops and throughout-day rewetting drops.

The right drop solves contact lens dryness in seconds rather than masking it. Refresh Plus PF is the safest first pick for sensitive eyes. Systane Ultra PF is the longest-lasting per drop. Soothe and Blink Tears Mild handle everyday mild dryness affordably. Match preservative load to use frequency and chronic dryness to TheraTears, and the lenses will feel like they did at hour one well into hour eight.
Frequently asked questions
Can I use regular eye drops while wearing contacts?+
Most regular eye drops are not approved for use with contacts because the preservatives can absorb into the lens and irritate the cornea. Look specifically for drops labeled contact lens compatible, contact lens rewetting drops, or preservative-free. Refresh Plus PF, Blink Tears Mild, and Systane Ultra PF are all safe to use with lenses in. Anti-redness drops like Visine should never be used with contacts in.
How often can I use rewetting drops?+
Preservative-free drops can be used as often as needed, even hourly during heavy screen use or air travel. Preservative-containing drops should be limited to four to six times daily to avoid preservative buildup on the lens. If you find yourself needing drops more than six times a day, the underlying problem is usually lens material mismatch or dry eye disease rather than something drops can fully solve.
Do rewetting drops actually rehydrate the lens?+
Yes, partially. Drops add a thin tear film layer over the lens and beneath it via the natural blink, restoring the wettability that lipids and protein deposits gradually degrade through the day. The effect lasts thirty minutes to two hours depending on lens type, ambient humidity, and your own tear quality. Lenses with bound-in wetting agents (Acuvue Oasys 1-Day, Total30) need drops less often than older hydrogel lenses.
Why do my contacts feel worse after using drops?+
Three common reasons. First, the drop contains a preservative your eye reacts to; switch to preservative-free single-vial drops. Second, you applied the drop with the lens displaced from center, trapping the drop under the lens edge; reposition the lens and try again. Third, the drop chemistry is incompatible with your lens material; switch to a drop labeled for silicone hydrogel specifically (Systane Ultra PF works on all materials).
Should I take drops with me when I fly?+
Yes. Cabin air is the driest environment most contact lens wearers ever encounter, often at 10 to 20 percent humidity for hours. Pack single-vial preservative-free drops in your carry-on, use one vial per eye per hour during the flight, and consider removing lenses entirely for flights over six hours. Glasses on a long flight prevent a lot of next-day red eye.
