The formula is good so far for my dry eyes. I am not sure if the formula is right for me yet. Seems to be good! I probably prefer individual use packaging for peace of mind there isn’t germs possible. Review: OUR OPTHALMOLOGIST APPROVES OF THIS BRAND! - We have this set up on a subscription. I waited for a few rounds of deliveries so that I could really evaluate it. My hubby had Bell's Palsy a few years ago, and ever since then, he's had trouble with dryness in the eye that was affected. He's been using this and it works well for him. This week, we got him set up for cataract surgery, and the doc told him to use drops for dry eye many times a day leading up to the surgery. He showed the doc this bottle of drops (he had it in his pocket) and the doc approved of this brand. The doc told him this was a good choice and to continue using it. ## Features - Immediate dry eye relief: TheraTears EXTRA Dry Eye Therapy lubricating eye drops provide immediate relief from dry eye symptoms; this formula delivers EXTRAordinary relief with up to 12 hours of hydrating comfort - Instant hydration: TheraTears EXTRA eye drops restore eyes’ natural balance and deliver fast hydration relief for dry eyes, because hydration supports dry eye health - Electrolytes: TheraTears eye drops’ unique formula contains OxyLytes, the 5 vital electrolytes found in natural tears - Created by an ophthalmologist: The TheraTears formula was created by an ophthalmologist, following 18 years of research, for a one-of-a-kind eye drop - Doctor-recommended: TheraTears is a doctor-recommended brand (per ProVoice Survey data collected 9/1/23-8/31/24), created to bring balance and hydration to dry eyes; your purchase may be FSA/HSA eligible, check your health plan for details ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076YRWWR1 | | Active Ingredients | Sodium carboxymethylcellulose 0.25% | | Additional Features | TheraTears electrolyte formula corrects the salt imbalance that can cause dry eye symptoms | | Age Range Description | 18 years + | | Best Sellers Rank | #1,771 in Health & Household ( See Top 100 in Health & Household ) #8 in Dry Eye Relief Products #42 in Vision Products | | Brand | TheraTears | | Brand Name | TheraTears | | Container Type | Bottle | | Customer Reviews | 4.6 out of 5 stars 6,611 Reviews | | Dosage Form | Drops | | Flavor | No Artificial Flavor | | Global Trade Identification Number | 00358790007151 | | Included Components | eye drops | | Item Dimensions | 1.86 x 1.06 x 3.75 inches | | Item Form | Drop | | Item Nype Name | Eyecare | | Item Weight | 14.2 g | | Item dimensions L x W x H | 1.86 x 1.06 x 3.75 inches | | Manufacturer | Prestige Consumer Healthcare | | Manufacturer Part Number | 1708411 | | Model Name | TheraTears | | Model Number | 1708411 | | Net Content Count | 1 actuation | | Number of Items | 1 | | Package Type Name | R | | Product Benefits | Moisturize Skin | | Specific Uses For Product | Allergy | | Target Use Body Part | Eyes | | UPC | 358790007151 | ## Product Details - **Brand:** TheraTears - **Item Weight:** 0.5 Ounces - **Item dimensions L x W x H:** 1.86 x 1.06 x 3.75 inches - **Product Benefits:** Moisturize Skin - **Specific Uses For Product:** Allergy ## Images ![Extra Dry Eye Drops, Lubricating, 0.5 Fl Oz | Extra Dry Eye Therapy, Lubricating Eye Drops for Dry Eye, Multidose bottle, Up to 12 Hours Hydrating Comfort - Image 1](https://m.media-amazon.com/images/I/714PhmsILRL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Questions & Answers **Q: Where are these manufactured** A: The box says they are made in Switzerland.. I think they work great... **Q: it says "preservative free in the eye" . it does not have the warding on the box or bottle. why?** A: The preservative they use (apparently sodium perborate,) is called a "disappearing preservative" by other manufacturers that use it. It apparently decomposes soon after you put it in your eye. This is apparently better then "the old" preservatives, especially benzalkonium chloride" (BAK), which I and most other folks with bad dry eye avoid "like the plague". It is hard to avoid BAK. ALL the cheaper drops seem to have it. Strange that the manufacturer avoids this issue. I presume it is because of copyright or trademark issues to do with wording. If I remember correctly "Genteal" was the first to use what it described a a "disappearing preservative" in about 2010 or so. It is of note that any preservative could probably cause some folks problems. "YMMV" (your mileage may vary : ) There is only one (that I know of) bottled artificial tear product that is unpreserved. I tried it and had a "3 out of 5 star" experience as the bottle (which had a special "filter" built in to prevent contamination) was pretty hard to use: it required a LOT of "squeeze" (& I'm a guy with pretty strong hands). Many users so complained. It was too expensive and troublesome. The whole preservative question is very important. You can cause blindness and other horrible outcomes really quickly using a contaminated product (which the preservatives help to prevent). EXERCISE ALL CAUTION with eye drops! If you think you have damaged your eyes with drops, see an eye doctor without delay. **Q: what are the ingredients?** A: Hello, Active ingredient: Sodium carboxy-methylcellulose 0.25% ... Eye lubricant. Inactive ingredients: Boric acid, calcium chloride, Dequest®, potassium chloride, sodium bicarbonate, sodium chloride, magnesium chloride, sodium perborate, sodium phosphate, trehalose, and water for injection. Have a great day! **Q: Should there have been a protective wrapping on the bottle? I received mine yesterday and there was no protective wrapping on the bottle.** A: There is no protective wrapping; there are small plastic teeth at the bottom of the cap that break away when opening for the first time. If the cap unscrews without some force, it has been opened. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The extra dry drops feel good! *by J***K on July 10, 2026* This is a good product.
