The battle between drops and ultrasonic mist boils down to one key factor: surface contact efficiency.

The Physics Advantage:

• Drops rely on gravity, leading to uneven coverage.

• Ultrasonic mist disperses evenly, covering 95% of the ocular surface.

• Smaller droplets increase bioavailability of active ingredients (especially for drugs like cyclosporine).

Case Study:

A 2023 Journal of Ophthalmology study found ultrasonic sprays delivered 2.3x more hyaluronic acid to dry eye patients vs. drops over 8 weeks.

Who Benefits Most?

• Post-LASIK patients (less irritation upon application).

• Elderly users (easier to aim than traditional droppers).

Final Thought:

"Medicine shouldn’t fight biology—ultrasonic sprays work with your tear film instead of disrupting it."
