When to choose a tear supplement?
To choose the most suitable tear supplement, it is essential to understand your tear film. This element is crucial for keeping the cornea, conjunctiva, and eyelids healthy, performing several key functions:
- Lubricates the ocular surfaces
- Removes foreign bodies and dead cells
- Smoothes corneal irregularities for a smooth surface
- Protects against pathogens as a natural barrier
- Provides nourishment and oxygen to the cornea
When tear production is insufficient or of poor quality, the tear film cannot adequately perform these functions. This can cause discomforts such as burning, redness, dry eyes, or the sensation of a foreign body in the eyes. In these cases, a tear supplement can offer the necessary support to restore visual comfort.
Which tear supplement to choose?
There are several types of artificial tears and tear supplements on the market. Let's look at the main differences to help you find the right one for your dry eyes or irritated eyes:
Tear supplements with a diluting function
These supplements aim to restore the aqueous component of the tear film, retaining water for prolonged hydration.
- MERAMIRT Ophthalmic Solution: a tear supplement that thickens and stabilizes the tear film, creating a transparent and viscoelastic protective shield, ideal for those suffering from dry eyes.
Tear supplements with a stabilizing function
Made with ingredients like hyaluronic acid, these are indicated when tear production is scarce or qualitatively altered.
- Blu Yal A Free: contains 0.15% hyaluronic acid. It integrates deficient tear secretion, restoring the tear film and protecting the ocular surface, especially for contact lens wearers or after surgical procedures.
Tear supplements with a nourishing function
These products provide useful elements for the trophism of damaged corneal epithelium.
- LACRISEK Free eye drops: relieves burning, itching, and redness associated with dry eye syndrome or environmental factors.
Tear supplements with a protective function
Based on hyaluronic acid or other hydrating polymers, they enhance ocular defenses and protect the corneal epithelium.
- OPTO Red Free: formulated for red eyes, with hyaluronic acid, Echinacea extract, and amino acids. It strengthens the tear film's defenses and facilitates ocular surface repair.
- Blu Gel A Free: with a high concentration of sodium hyaluronate (0.30%), it offers long-lasting protection against mechanical stress and dry eyes.
- TRIUM Free eye drops: with sodium hyaluronate and Ginkgo Biloba, it hydrates and protects the ocular surface in cases of irritation, allergies, or excessive contact lens use, promoting epithelial regeneration.
The importance of nutrition for the tear film
In addition to external tear supplements, nutrition plays a key role in eye health. A balanced diet can support the tear film and prevent problems like dry eyes.
Dietary supplements for the eyes
Beyond external tear supplements, dietary supplementation can stabilize the tear film and improve ocular health from within.
- LUTEIN Omega3: a dietary supplement with lutein, zeaxanthin, and DHA from fish oil. It supports visual capacity, protects against oxidative stress, and promotes the health of ocular blood vessels, contributing to a more stable tear film.
- Meramirt CM 30 tabs: a supplement for those suffering from visual fatigue and tired eyes, often associated with dry eyes from prolonged screen use.
- Meramirt XG 20 tabs 500 mg: a high-dose formulation for visual support in cases of eye fatigue and stress.
- Vitreoxigen: formulated for those suffering from floaters ("muscae volitantes"), with amino acids, magnesium, and antioxidants. It helps maintain the health of the vitreous body.
The substances contained in these supplements contribute to:
- Maintaining normal vision (Zinc, DHA, Vitamin A)
- Protecting the
