Description
Overview
How does Tears Naturale Artificial Tears Eye Drops (15ml) mimic natural tears? Tears Naturale utilises a specific formulation known as the Duasorb system. This system combines two water-soluble polymers: Dextran 70 and Hypromellose. These ingredients work synergistically to replicate the characteristics of the natural conjunctival mucus. Dextran 70 acts as a volume expander which mimics the aqueous (watery) layer of the tear film while Hypromellose functions as a lubricant that simulates the mucin layer. When Tears Naturale is applied to the eye, this combination lowers the surface tension of the tears. This physical change ensures that moisture spreads evenly across the cornea and adheres to the surface rather than draining away immediately. This adherence provides a stable and long-lasting wetness that relieves the gritty sensation of dry eye syndrome.
Why is the Polyquad preservative in Tears Naturale Artificial Tears Eye Drops (15ml) significant? Many standard eye drops use a preservative called Benzalkonium Chloride (BAK) to prevent bacterial growth in the bottle. However, BAK can be toxic to the corneal cells and may cause stinging or inflammation with long-term use. Tears Naturale is formulated with Polyquad (Polyquaternium-1) as the preservative. Polyquad has a much larger molecular size than BAK which prevents Polyquad from penetrating the cells of the eye surface. This makes Tears Naturale significantly gentler on the ocular tissue and reduces the risk of reaction for patients who have sensitive eyes or require frequent dosing throughout the day.
How does Tears Naturale Artificial Tears Eye Drops (15ml) protect the cornea? Chronic dryness often leads to the breakdown of the tear film which exposes the corneal epithelium to the air and causes dry spots. These dry spots can lead to microscopic abrasions and discomfort. Tears Naturale increases the viscosity of the tear film without making the solution sticky or blurring vision excessively. By enhancing the stability of the tear film, Tears Naturale prevents rapid evaporation and covers these dry spots. This protection allows the corneal surface to remain smooth and lubricated which is essential for clear vision and preventing further irritation from blinking friction.
Who Is It For
Who is Tears Naturale Artificial Tears Eye Drops (15ml) suitable for? Tears Naturale is suitable for adults, the elderly, and children. Tears Naturale is specifically indicated for the treatment of dry eye conditions including Keratoconjunctivitis sicca and recurrent corneal erosion. Tears Naturale is an ideal choice for individuals who experience eye fatigue due to environmental factors such as wind, smoke, air conditioning, or prolonged screen use. Tears Naturale is suitable for patients who find other preservative-containing drops too harsh but do not wish to use single-dose units.
Usage Instructions
How to apply Tears Naturale Artificial Tears Eye Drops (15ml) correctly? Tears Naturale is for ocular use only. The user should wash hands thoroughly before handling the bottle. To apply, the user must tilt the head back and look at the ceiling. With one finger, the user should gently pull down the lower eyelid to create a small pocket. The bottle of Tears Naturale should be held upside down above the eye. The user must squeeze the bottle gently to release one or two drops into the pocket. It is crucial that the dropper tip does not touch the eye, eyelashes, or skin to prevent contamination of the solution. After application, the user should release the eyelid and blink a few times to spread Tears Naturale across the eye surface.
Can Tears Naturale Artificial Tears Eye Drops (15ml) be used with contact lenses? Although Polyquad is gentler than other preservatives, the manufacturer generally advises that soft contact lenses should be removed before applying Tears Naturale. The ingredients can occasionally interact with the soft lens material. Users should remove their lenses, apply Tears Naturale, and wait at least fifteen minutes before re-inserting the lenses. Hard contact lens wearers should consult their optician regarding compatibility.
Warnings
When must Tears Naturale Artificial Tears Eye Drops (15ml) not be used? Tears Naturale must not be used by patients with a known hypersensitivity or allergy to Dextran 70, Hypromellose, or any of the excipients. If the user experiences eye pain, changes in vision, or persistent redness after using Tears Naturale, use must be discontinued and a doctor consulted. Tears Naturale should be discarded four weeks after first opening to ensure the product remains sterile.
Alternatives
Common alternatives to Tears Naturale Artificial Tears Eye Drops (15ml)? If Tears Naturale is not suitable due to the preservative or viscosity, common alternatives include:
Hypromellose 0.3% Eye Drops: A standard generic artificial tear containing only one polymer, often cheaper but may not last as long on the eye as the dual system in Tears Naturale.
Sno Tears 1.4% Eye Drops: Contains Polyvinyl Alcohol which offers a different type of lubrication that some patients find less sticky than cellulose-based drops.
Viscotears Liquid Gel: A carbomer-based gel that is significantly thicker than Tears Naturale, staying on the eye for much longer but causing more blur, making it better for night use.
Artelac Rebalance: A multi-component drop containing Vitamin B12 and Hyaluronic Acid designed to nourish the eye surface as well as lubricate it.
Hycosan Original: A preservative-free solution containing Sodium Hyaluronate in a specialised bottle, suitable for patients who cannot tolerate any preservatives like Polyquad.
