Best for: Relieving dryness that doesn’t respond to other remedies.
How they work: Available only by prescription, Lacrisert inserts are tiny cellulose beads that you place in the pocket of each lower eyelid. “They dissolve slowly and mix with your tears to provide ongoing lubrication throughout the day,” says Pflugfelder.
How to use them: Insert a bead once or twice a day. Like prescription drops, inserts are safe for long-term use, as directed by your doctor.
