Medication Usage


Understanding Dry Eyes Starts with the Tear Film

The tear film

The tear film

is the outermost layer of the eye that constantly comes into contact with external irritants, helping to moisturize and protect the eyes.

The tear film consists of three layers,

each with its own unique functions

According to research reports, there are over 400 million dry eye syndrome patients worldwide, and the prevalence of dry eye syndrome continues to increase with age, with a sharp rise in patients around the age of 50. The causes of dry eye syndrome are commonly believed to be primarily associated with prolonged use of electronic devices, but in fact, there are numerous factors that can lead to dry eyes.

Dry eye

Dry eye syndrome is not solely defined by insufficient tear secretion and can be broadly categorized into three types:

1.Aqueous-deficient type

1.Aqueous-deficient type

This type occurs when the lacrimal glands degenerate, get damaged, or function abnormally, leading to reduced tear production.

2.Evaporative type

2.Evaporative type

The meibomian glands, located at the base of the upper and lower eyelashes, are responsible for secreting oil and forming the lipid layer. A stable lipid layer helps reduce evaporation of the "aqueous layer." Insufficient secretion from the meibomian glands leads to continuous thinning of the lipid layer, resulting in rapid evaporation of the aqueous layer. This is often referred to as "meibomian gland dysfunction."

3.Mixed type

3.Mixed type

The majority of dry eye syndrome patients have a mixed type, which is characterized by a combination of the above two symptoms.

There are numerous methods to relief dry eyes, including artificial tears, light therapy, wearing specialized eyeglasses, and eye-protective nutrients, among others. Among these, the use of natural and preservative-free lubricating eye drops is the most common approach to relieving symptoms.

What is Hyaluronic Acid?


Hyaluronic Acid

is a highly effective moisturizing factor and a substance naturally produced in the human body. It is particularly abundant in the eyes and joints, where the liquid has the highest concentration of Hyaluronic Acid.

This hydrophilic molecule can hold a large amount of water and carry water that is 1000 times its own weight.

Each blink forms a protective film for the eyes, providing long-lasting hydration, nourishment, and fatigue relief.

Due to the high binding capacity of hyaluronic acid with water and the high physical-chemical similarity with the glycoproteins of the corneal mucosal layer, it has an excellent ability to bond to the ocular surface, performing the following actions on the eye in case of suffering from Dry Eye:

  1. Hydration, moisturization, and fatigue relief

  2. Improvement of corneal epithelial cell condition

  3. Enhancement of tear film stability

Experience the difference with HYLO® Hyaluronic Acid!

Hyaluronic Acid brings you infinite possibilities.

Why are preservative eye drops being replaced?

Preservative eye drops were commonly used to prolong their shelf life. Preservatives not only eliminate microorganisms but can also damage the normal ocular surface tissue.

Long-term use of eye drops containing preservatives can be toxic to ocular surface cells, including corneal epithelium and conjunctiva. It can lead to corneal epithelial cell death, corneal punctate ulcers, delayed corneal wound healing, conjunctivitis/conjunctival fibrosis, unstable tear film, dry eye symptoms, allergic reactions, eye discomfort, and more.

The higher the concentration of preservatives, the more pronounced these side effects can become.

Preservative eye drops:

Preservative eye drops:

Preservatives not only have the ability to eliminate microorganisms but also to a limited extent disrupt the cell connections between corneal epithelial cells. The purpose is to facilitate the penetration of medications into the cornea. While this can enhance the local effect of the medication, it also reduces corneal epithelial cell activity and cell adhesion. Preservatives can also disrupt the lipid layer of the tear film, making the eyes more prone to dryness and discomfort.
