The natural tear film is made up of three layers that work together to keep eyes lubricated and free of foreign particles, reduce the risk of infection, and maintain a smooth, clear eye surface.

1. Mucin Layer – enhances tear adhesion to the surface of the eye.

2. Aqueous Layer – provides moisture to the eye and flushes out irritants.

3. Lipid Layer – slows tear evaporation and helps tears remain on the eye.

Unlike most over-the-counter eye drops that only work on one layer of the tear film, Rohto Dry-Aid works in a unique way to restore moisture to the tear film by working on all three layers to mimic a stable, natural tear.

Rohto Dry-Aid, with LiquidShield Technology, helps restore your natural tear film to create a uniform moisture shield that is clinically shown to soothe eyes for up to 12 hours.
