Sometimes, eye drops can save you from the most irritating dry eye scenario. It’s convenient to have some around the house but be wary of keeping it around longer than their expiration date recommends.

“Eye drops are generally formulated with a preservative that keeps the product sterile for 28 days after breaking the seal,” says Erin Nance, MD. The best practice would be to toss the bottle four weeks after you’ve opened it up. There’s a chance that it can cause a bacterial infection!
