RAIN, a well-known brand, came in as the best dry eye drop contender, from the work done by our researchers and testers, and also recommendations from an Ophthalmologist. Not only were they impressed by the topnotch eye moisture results, they found the product safe for daily use with its preservative free formula, and the long lasting relief it provides. Some people asked us how the drops feel when going into your eye, as that can be a common concern when using artificial tears often, however with the Rain Eye Drops simple formula, it provided rapid relief with no sensitivity and no blurry vision reported.

The number one feature that separates Rain Eye Drops from other brands on the market is the brands dedication to being 100% Preservative Free, and using the most simple formula possible to avoid irritating already sensitive dry eyes and maximizing relief.

Rain Eye Drops is the only brand on the market that offers a 100% Preservative Free line of eye drops with a more natural formula free from harsh chemicals, the #1 essential element for lasting dry eye relief and protection.

When using products in the eyes, special care must be taken with formulation and ingredients, and product quality. Our researchers and tester felt very comfortable with the preservative free, non-GMO formula produced only in FDA approved facilities with a solid reputation. Above all, they were ecstatic with the lasting dry eye relief and the ability to keep their eyes nourished with RAIN’s Eye & Vision Support vitamins alongside the preservative free lubricating eye drops they offer.

RAIN is based in the USA, and they offer free fast shipping and a 30-day money-back guarantee on all vision products.

Systane Ultra eye drops are designed for dry eyes but not for frequent use. They recommended “use it as needed” with only 1-2 drops per eye per use. The reason for this may be due to the formula. While better than most, these eye drops still contain some preservatives that can cause irritation in your eyes. If you have sensitivity or severe dry eye then its best to find an alternative with a list of more gentle ingredients, especially if you use eye drops often.

Walgreens knows what they’re doing when it comes to personal care products. Their effective preservative-free formula works to rejuvenate dry eyes and moisture without causing irritation from daily use. The product also has numerous reported benefits.

Unfortunately, finding the product can be inconvenient and the $26.41/oz price is quite high. Thankfully, there are other high-quality eye care products that have both preservative-free formulas and convenient online ordering at a lower price.

Thera Tears is owned by Akorn, an American generic pharmaceuticals manufacturer. The company develops, manufactures and markets generic and prescription drugs as well as animal and consumer health products.

Earlier last year, Akorn filed for bankruptcy after unease surrounding its quality control methods resulted in a failed takeover bid and warning letters from the US Food and Drug Administration (FDA). Their line of eye drops mostly contain preservatives which gives them a longer shelf life and cheaper packaging requirements.

Retaine MGD’s main ingredient is mineral oil. This formula may be problematic for some users due to blurriness caused in the eye. So it may be best to use it at bedtime and not during the day. Products like this contain glycerin with polysorbates, among other ingredients, so they may have a milky appearance. Some eye drops need to be shaken before use. Our reviewers noticed an increase in eye mucus (also known as “eye boogers”) around our eyes after each use due to all of the thick mineral oils.

The Visine formula was created in the 1990s by a team that wanted to remove redness from the eyes. This makes for an impressive history and a unique story, but recent advances have made eye drop products even better and more suitable for dry eye symptoms. Visine works as a simple redness remover so our testers were disappointed. Other eye drop products do so much more for actual dry eye relief and lubrication.

Lumify has a wide distribution and actually uses less harmful chemicals in its ingredients than other redness removers. Although it was formulated with doctors leading the studies, reading about how the active ingredients actually work leads you to the realization that this product is not designed to relieve dry eye symptoms. The active ingredients in fact are intended to constrict blood vessels in the eye to cover up redness. This puts a bandaid on the issue and does not address the root cause of dry eyes, which is lack of moisture on the lipid layer.
