Dry Eye Intense Drops - Preservative Free Eye Drops - Multidose Bottle - Step 3 Hydrate - .33 fl oz, 300 Doses

OPTASE for dry eyes is wonderful! It really helps the awful dryness I have felt for a very long time. I highly recommend the product.

Great drops that stop my lids from sticking due to dry eye for longer than other drops I have tried.

My eye doctor recommended I buy these. She said this is the safest clean eye drops. They are good, squirts well nice and slow.

Works well if used twice and day every day. Does not work at all if eyes are already dry. Bottle is terrible. It is impossible to dispense eye drops once the bottle is below half full. It also clogs easily and gets a black mold/fungus if you leave it in the car by accident. What was wrong with the traditional glass eye dropper?

Good amount. Thicker mix, yet still able to see. Stays in the eyes. Great price.

Although, the drops work well for dry eyes for most people, many people complain about the bottle. They complain they need to squeeze so hard to get the first drop out, they frequently get, instead, multiple drops or a stream of drops. Why is this bottle designed this way, you might wonder. The simple answer is that in order to keep drops sterile in a multiuse bottle, the bottle had to be designed to let drops out when you squeeze, but not allow contaminants to be sucked into the bottle when you release. These contaminants could be in the air around you or on the tip of the bottle had it unintentionally touched anything. So the bottle was given a flatter dispensing end to keep the tip out of your eye. It has a blue exit point instead. (More on that latter). Inside there is a one way valve, that stays closed until you use the drops. (See picture) . When you squeeze the bottle, an extremely small flow of liquid opens the valve to allow the drop to exit, but this requires more time to deliver the drop, than a conventional bottle not having the resistance of such a valve. If you impatiently squeeze too hard, two things happen. 1. Multiple drops may be dispensed. 2. Air that is packaged in the bottle above the liquid may be forced out of the bottle along with the drops. (If the bottle his held vertically while instilling the drops, the latter is less likely to happen.) Since the valve works in only one direction, as the bottle empties and no air gets back in, a vacuum is created causing the bottle to collapse, making it more difficult to squeeze out every bit of its contents. Optase says they overfill the bottle beyond the claimed 0.33 ml, to give you a usable 0.33 ml, even though some remains in the totally collapsed bottle. Given the necessity for this design, in order to keep preservative free drops sterile, is there any easier way to dispense drops? Here is my procedure: 1. After removing the cap, be careful to keep the blue tip from touching your face or eye. 2.Imagine the blue tip to be a "bulls eye" upon which you will focus while squeezing the bottle. 3. Sit in an easy chair or sofa and steady your head backwards against the back, so that you are looking at the ceiling. 4. Hold the bottle vertically over your eye so that you can focus on the blue tip. Position the bottle so the "blue bulls eye" is in the center of your view close to your eye. 5. Squeeze the bottle with steady pressure until a drop begins to form on the blue tip. As it begins to form, the blue target becomes somewhat blurred, but continue squeezing until the drop actually drops into your eye. (Be patient while squeezing. It may take up to 15 seconds for the first drop to actually drop.) Squeezing harder will not speed this up and may result in wasted extra drops. After the first drop, the next drop will take less time. 4. After administering the drops, be sure to shake off, in a horizontal direction, any extra liquid that may remain on the blue tip. If you fail to do this before recapping the bottle, that extra drop my cause mold to form inside the cap. 5. Tighten the cap completely after use. All of this seems like a pain, especially if you are accustomed to drop bottles that contain preservatives and don't need bottle of this design. (BTW, Optase is not the only maker of preservative free drops, who use this bottle. Both BioTrue and Systane make preservative free versions in the same bottle.) Unfortunately Optase doesn't give you a choice of daily vials that Systane and BioTrue also offer. If you don't want the hassle, check out BioTrue drops in single use vials. They have nearly the same ingredients as Optase and probably work nearly as well. The downside of single use vials is they are more expensive than a multiuse bottle. Perhaps, because Optase is already so expensive in a preservative-free multiuse bottle, they don't offer single use vials. It could be most people couldn't afford them.

These drops were recommended to me by my optometrist. These are really good drops. They last longer than most brands on the shelf and provide immediate cooling and comfort for dry eyes.

The drops are soothing & bring relief. I recommend the drops but the problem is the bottle. One of the better eye drops in one of the worst bottles. The spout could be longer, which would improve the success rate of the droplet hitting the target. I will buy again but be warned. Frustrating. The drops 5 stars … & the bottle 1 star … for an overall score of a 3.
