👉 The Cindy fluid, also known as Cindy's fluid or Cindy's serum, is a synthetic, viscous solution used in medical settings, particularly in ophthalmology. It was developed to mimic the natural tear film and is primarily composed of hyaluronic acid, which helps maintain the integrity and stability of the tear film on the eye's surface. This fluid is crucial for patients with dry eye syndrome or other conditions that affect tear production, as it provides lubrication and comfort, reducing irritation and improving visual clarity. The Cindy fluid is typically applied as a drop or spray to the eye and is designed to adhere to the ocular surface, offering sustained relief from dryness and discomfort.
