Optase Dry Eye Intense Drops, Single Dose - Preservative Free Drops for Long Lasting Relief - Artificial Tears to Relieve Severe Dry Eye Symptoms - 30 Single Dose Vials

I recently purchased the Scope Eyecare Eye Drops, and I couldn't be happier with the results. Suffering from dry eyes, I've tried numerous products over the years, but this one truly stands out. The relief is almost instant, providing long-lasting moisture and comfort. The drops are easy to apply and don't cause any irritation, unlike some others I've tried. I also appreciate the thoughtful packaging, which makes it easy to carry with me wherever I go. Overall, I highly recommend these eye drops to anyone in need of effective and soothing eye care. A must-have!

I was worried about using this product after reading all the 1 star reviews complaining of mold growth under the cap, but decided to try it since I had already bought this nonreturnable item. The instructions on the label & in the package insert clearly state that you must shake off any residual liquid from the bottle top before replacing the cap. I do this every time with a vigorous flick of the bottle over a tissue, sink or trash can. I wipe off the residual liquid with a tissue if necessary. The drops work great for me & I have not had any mold growth after a month of use. The item is expensive, but I just ordered another bottle because the drops have greatly improved my dry eye symptoms.

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.

Worked great for my dry eyes, but I really don't like the way it despenser the drops. It tends to stick to the top of the bottle and drip off the wrong way. The drops themselves really are great though.

Functions as described, helps my dry eyes immensely especially when wearing my contact lenses. The bottle is kinda small, but absolutely worth the money. It helps my dry eyes almost instantly. They don’t burn like some of the other ones.

Optase works quickly to reduce the burning of my dry eyes. I have found it to be more effective than others I have tried. Easy to use and small enough to carry in my pocket or purse should I need to use more during the day. Lasts 7-12 hours depending on humidity in your home or outside on a windy day.Would definitely recommend it. Difficult to find in my local stores however is available on Amazon.

I suffer from extreme dry eye. I think I have tried every drip on the market. Actually having IPL therapy on my eyes because it’s so bad. Hands down, best drops on the market! Highly recommend for those with dry eyes.

I was excited to possibly have a new dry eye drop that was going to HELP...it's a good size, quite a bit of medication. Before ordering I watched a couple of videos so I knew about the bottle problem, not letting air go back inside. My first thing when I tried to OPEN the darn thing, so I struggled with it for half an hour, my son came over to help, he got it open right away, BIG PROBLEM it collapsed somewhat, so without even getting to try one drop. I'm using it and it does help but it will not get any better, I've tried to use a blunt needle to push straight down gently...it does not solve the problem. It does provide comfort, I think its a good product, it might help with itching. Providing value? Not if I cannot use every drop??
