As the medical establishment\u2019s understanding of the physiology, symptomatology, and treatment of dry eye disease is continually refined, the OTC eye care product industry is responding with a broad selection of targeted solutions. <\/p>\n\n\n\n

With this increased specialization, and with the general trend towards a more competitive market, consumers now have dozens of over-the-counter eye drop products and brands to choose from.<\/p>\n\n\n\n

More options and medical jargon means more questions on the consumer end, which is why we are comparing four of the most prominent brands in the eye drop industry.<\/p>\n\n\n\n

How do Rain, Retaine, Systane, and Refresh eye drops stack up against each other? <\/p>\n\n\n\n

This critical comparison will examine the product offering, ingredient lists, and cost of each of these industry frontrunners to help you enter the proper frame of mind for a smarter purchase. <\/p>\n\n\n\n

The central theme throughout all of Rain\u2019s messaging is focused on a gentle, preservative-free eye drop formulation that actually works for dry eye disease and associated symptoms. <\/p>\n\n\n\n

Rain\u2019s eye drops<\/a> are moisturizing tears formulated to lubricate the eye and soothe irritation – here\u2019s a closer look at how.<\/p>\n\n\n\n

How Rain Drops Treat Dry Eye<\/h3>\n\n\n\n

Using carboxymethylcellulose sodium (0.5%), or CMC, a research-proven compound for safely lubricating the ocular surface, Rain eye drops attack dry eye disease symptoms with minimal risk of adverse reactions. CMC has been evidenced to facilitate a healthier tear film breakup time, meaning it can provide more sustainable benefits beyond instant relief from that itchy, irritated feeling. Here are the inactive ingredients:<\/p>\n\n\n\n

Calcium chloride, hydrochloric acid, magnesium chloride, potassium chloride, purified water, sodium chloride, sodium hydroxide, and sodium lactate. <\/p>\n\n\n\n

Rain\u2019s Preservative-Free Formula for Red, Dry Eyes<\/h3>\n\n\n\n

In the current context of the eye drop industry, Rain eye drops are just as valuable for what they do not contain – harsh preservatives and other additives – as for what they do contain. <\/p>\n\n\n\n

Though it\u2019s obviously not recommended, you could actually drink these 100% preservative-free drops because they are that gentle. <\/p>\n\n\n\n

Paradoxically, OTC eye drop products from the vast majority of competitors who do use preservatives can actually worsen dry eye disease as the body responds to these foreign irritants. <\/p>\n\n\n\n

Finally, Rain doubles down on this commitment to providing the industry\u2019s safest OTC eye drop with their blow-fill-seal process for sterilizing containers.<\/p>\n\n\n\n

Where to Buy and How Much?<\/h3>\n\n\n\n

Rain eye drops are available exclusively on the company website<\/a>. Each box contains 30 single-use containers. Even for more competitive brands, savings scale up rather aggressively with incremental increases in quantity. Here is the current pricing structure:<\/p>\n\n\n\n
