Optase Dry Eye Intense Drops - Preservative Free Eye Drops for Long Lasting Relief - Artificial Tears to Relieve Severe Dry Eye Symptoms - Multidose Bottle - Step 3 Hydrate - .33 fl oz, 300 Doses

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.

I was having irritation and eye strain for months. My regular tears eye drops were not helping anymore maybe making it worse. My optometrist recommended these. I immediately felt better the first time I used them. I kept using them daily twice a day and I kept improving. I think that after so much use it was the preservatives on my regular drops that ended up giving me problems. I plan to always have these available. I highly recommend.

I had cataract surgery several weeks ago and now can see with no contacts or glasses only problem has been excessive dryness and in evenings especially having the feeling that i need to take my contacts out for relief, which i dont have in, from the scratchy feelings. I tried this and it’s the best eye drop i have tried since the surgeries. I have tried several others but i was needing to put them in all day to get comfort. These drops made a world of difference. Highly recommend. So far ive not had any problem with mold growth but i do shake them off and if i suspect any liquid present on the top or sides before i put the top back on the bottle i take a new tissue and dab lightly just in case. I would rather take the chance to have a micro amount of tissue debree as opposed to mold growth ruining my expensive eye drops.

I didn’t get a chance to use it because I realized once I got it that it had it ingredient in it that I’m unable to use. It has Trometamol as an anti inflammatory. I am allergic to ibuprofen and this may contain Ketorolac ( a form of NSAID’s ) as part of the Trometamol. Glad I checked before using 😬

These are my favorite eye drops. They don't sting my eyes. They help your eyes stay moist. They help with dry eye.

These drops help immensely with dry eye! First over the counter I n habe found that helps!!!

El alivio que aporta es inmediato y dura bastante tiempo los ojos hidratados. Mi esposo las usa a diario, son ideal si pasas mucho tiempo frente al teléfono o manejando en carretera.

I’m giving this product 3 stars—not because the eye drops themselves are bad, but because the packaging is incredibly frustrating. As someone with dry, sensitive eyes who wears contacts daily, I appreciate a preservative-free formula, and these drops are fine in that respect.However, the bottle is a total dealbreaker. It doesn't dispense drops well, and if you squeeze it even slightly too hard, it collapses and doesn’t return to its original shape. It makes using the product annoying and wasteful.Honestly, save yourself the hassle and try Biotrue Hydration Boost Eye Drops instead. They're preservative-free, contact lens–friendly, and come in a bottle that actually works. Highly recommend.
