Not only were they impressed by the topnotch eye moisture results, they found the product safe for daily use with its 100% 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.

What sets Rain Eye Drops apart is their commitment to a 100% preservative-free formula, using only clean ingredients designed to help avoid irritation, deliver consistent relief, and support a healthier vision care routine, giving you more control over your eye comfort.

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.
