Ideal for dry or irritated eyes! Refresh Endura® provides excellent lubricating action and prolonged retention on your eye – giving you long-lasting protection from the dry, burning, scratchy sensations associated with dry eye irritation. Just as important, to avoid the use of potentially irritating preserving agents that are foreign to your natural tears, Refresh Endura® comes in preservative-free, air-tight containers. You can, therefore, apply Refresh Endura® without the risk of preservative-induced irritation.
