That’s right: nowadays between wearing contact lenses, reading on computer screens and smartphones, air pollution, dust (and you name it!) our eyes are often subject to disorders such as classic “dry eyes” or “red eyes,” and so on.

And there you immediately think of the most obvious solution: the famous eye drops!

Let’s look at what is meant by eye drops and which natural preparations are most commonly used to relieve the symptoms of some of the most common eye disorders.


“Eye drops” refers to an aqueous solution, usually saline, that is prepared and used to relieve the symptoms of some fairly common eye conditions, such as dry eyes, red eyes, tired eyes (and so on). Eye drops can also be actual medications and therefore used to treat ailments such as allergies, conjunctivitis (bacterial or viral), inflammation or other problems; however, in these cases it is advisable to always refer to the doctor’s instructions.

In this article we focus on natural ingredients used in the preparation of eye drops.


DRY EYES EYE DROPSDry eye is defined as a multifactorial disease involving the balance of tear fluid and ocular surface. Thus, it is a pathological condition that, in addition to being very annoying, can cause tear film instability and visual disturbance. It is very important to treat these symptoms early to avoid long-term damage to the ocular surface!

From what then comes the classic “dry eye”? This phenomenon can generally be attributed to reduced tearing, or to altered tear composition.

There are many causes of this disorder: air pollution, living in dry and dusty environments, heating and air conditioning, excessive sun exposure, allergies, prolonged use of computers and smartphones, daily use of contact lenses, smoking…

As you can see, it may not be that uncommon to incur this disorder. How to deal with it? Are there natural remedies to counteract the annoying symptomatology? The answer is Yes!

Let’s look at what natural ingredients we can use to prepare eye drops.


Hyaluronic acid is a linear polysaccharide formed from disaccharide units containing N-acetyl-D-glucosamine and glucuronic acid. Due to its viscoelastic properties, hyaluronic acid is one of the most widely used active ingredients in dry eye therapy.

In particular, the high water retention of this molecule (i.e., the ability to absorb water molecules in the surrounding environment) is exploited to improve the hydration of the precorneal area: this is why hyaluronic acid is widely used in most tear substitutes aimed at treating dry eye syndrome.

Another characteristic of hyaluronic acid is its mucoadhesiveness: essentially, it allows it to create a stable and durable coating that is useful in protecting the surface of the cornea. In addition, its property of restoring the secretion of lactoferrin and defensins B (produced by conjunctival epithelial cells) allows the physiological ocular bacterial population to be reestablished, thus favoring what are “friendly bacteria.”

So what benefits do hyaluronic acid eye drops provide? Definitely long-lasting hydration, as well as lubricating and protective properties, which allow it to impart considerable relief to the eyes in case of irritation, burning, and sensation of foreign covering!


Many eye drops for the treatment of dry eye are prepared with distilled waters of plant origin. Due to the properties of the plant extracts of which they are composed, plant distilled waters contribute to the beneficial action of eye drops.

Let’s see together which plants are most commonly used for this purpose!

  • AMAMELIDE. It is a plant is widespread in the moist forests of Canada and the eastern coasts of the USA. The main components of the witch hazel plant are tannins (3-8%); flavonoids and essential oil, concentrated mainly at the leaf level, are also present. The plant has several properties, including vasoregulatory and vitamin-P-like properties. Thanks to the anti-inflammatory action of its components, Witch Hazel relieves irritation and redness, provides rapid relief and reduces burning sensation, thus making it a valuable aid in dry or reddened eyes.
  • CAMOMILE. It is an herbaceous plant currently widespread throughout Europe, the Americas and Australia. It has topical anti-inflammatory properties: these are mainly due to its flavonoid content, particularly apigenin, a compound that can intervene in the mechanism of inflammation at different levels (vascular and cellular). It also contains coumarins and polysaccharides, which are characterized by anti-inflammatory and immune-stimulating activity.
  • EUFRASIA. It is an herbaceous plant widespread in Europe, northern Asia and North America. Due to its flavonoid and tannin content, this plant has potent anti-inflammatory, antibacterial, and decongestant action. Because of these properties it is widely used in the treatment of eye disorders, including irritated eye states and dry eyes.
  • MALLOW. It is a herbaceous plant native to Europe, western Asia and America. Its main components are mucilages, present in all parts of the plant and responsible for its emollient action. The leaves contain coumarinic acid, chlorogenic acid, caffeic acid, tannins and vitamins.

DRY EYE DROPSMallow has emollient and refreshing properties: the mucilages in the plant, in fact, are adsorptive toward secreted substances, play a cooling role and counteract local irritation by forming a protective layer.

The plant also has a powerful anti-inflammatory, soothing and vasoprotective action, proving particularly useful in promoting the well-being of the eye!

  • MYRTLE. It is a small shrub common in coniferous forests in Europe, Asia and North America.

Blueberry extract is believed to be a natural nourisher for the eyes. In fact, blueberry is extremely rich in substances that act as active ingredients in promoting its health benefits. Among these, anthocyanins, a group of flavonoids widespread in the plant kingdom that have numerous pharmacological activities, play a prominent role. Most important for visual well-being are anti-inflammatory and antiplatelet action, strengthening of the connective tissue that supports blood vessels, and increasing resistance and reducing capillary permeability.

We have seen how “easy” it can be nowadays to suffer, even sometimes, from dry eyes… The important thing is to know how to deal with the problem (and possibly prevent it!) and to know its main remedies, remembering in this regard that Nature can prove to be an excellent ally!
