“If you’re using eye drops every day, you should talk to your doctor,” says Michael Orozco, OD, an optometrist with MCOA Eyecare in San Antonio, Texas. “The use of eye drops should be temporary. For long-term, your doctor can recommend a permanent treatment program including blinking exercises, and anti-inflammatory medications [and] treatments to unclog the tear glands.” According to the American Academy of Ophthalmology (AAO), there are two kinds of OTC eyedrops you’re most likely to encounter: artificial tears and redness-relieving drops. Orozco says artificial tears are used in patients who have dry eyes, as they “replace the tear film that your body should be naturally producing.” However, they’re only meant to provide brief relief. “Many over-the-counter artificial tears contain preservatives that can cause damage to the delicate skin on the surface of the eye if used frequently,” Orozco explains. “And, if used frequently, they may be masking an underlying disease process that needs to be identified and treated. " According to Orozco, artificial tears are made mostly of salt and water to help temporarily relieve pain from dry eyes, but they actually “lack the natural oils, minerals, and protective enzymes” found in real teardrops. So while you may feel relief in the moment, it’s no substitute for natural tear film. “If you are using drops frequently but still feel grittiness, stinging, burning, debris on the lids margins, or blurry vision, then you need to address the root cause of the problem, and stop treating just the symptoms,” he says. “Failure to treat the underlying disease will allow the disease to progress, often causing permanent damage to the tear glands and ocular surface.” The other type of OTC eye drops, redness-relieving drops, typically reduces redness by “constructing conjunctival blood vessels,” says Benjamin Ticho, MD, a pediatric ophthalmologist who specializes in cataracts, glaucoma, and strabismus treatment. “While generally temporarily effective in reducing redness, they are not treating the cause of the blood vessel dilation, just covering up the undesirable appearance,” Ticho says. Even worse, these drops typically have a “rebound effect” that makes eyes worse off than they were with just the initial redness, according to Ticho. And that’s usually what causes people to enter a vicious cycle of reusing redness-relieving drops too often. He says he recommends these eye drops for temporary use prior to an important event, but not for regular use—especially daily use.
