Preservative-Free Artificial Tears
for Dry Eyes
Single-dose unit eye drops without preservatives, essential for users applying drops more than 4 times daily or those sensitive to preservatives which can worsen dry eye.
How it works
Preservatives such as benzalkonium chloride (BAK) are cytotoxic to the ocular surface epithelium, perpetuating inflammation in frequent users. Preservative-free formulations avoid this toxicity.
What to watch for
More expensive than preserved drops. Single-use vials should be discarded after opening. Required for contact lens wearers.
