EvoTears Eye Drops - 3ml

What Are EvoTears Eye Drops and How Do They Help Dry Eyes?

EvoTears eye drops are a preservative-free ocular lubricant designed to relieve the symptoms of dry eye disease (also called keratoconjunctivitis sicca). Dry eye is surprisingly common — the NHS estimates it affects millions of people in the UK, causing discomfort, grittiness, redness, and blurred vision that can interfere with everyday tasks like reading or using a screen. If you've tried conventional eye drops and found them short-lived or irritating, EvoTears may offer a different approach worth considering. You can explore the full range of products available in our eye care collection to find the right option for your needs.

Each 3ml bottle contains perfluorohexyloctane (F6H8) as the sole active ingredient — no preservatives, no phosphates, no water. That's quite different from most lubricating drops on the market. The product is manufactured by Ursapharm and is available over the counter without a prescription.

How Do EvoTears Eye Drops Work to Relieve Dry Eye?

The mechanism behind EvoTears is rooted in the structure of the tear film itself. Your tear film has three layers: a mucin layer closest to the eye, an aqueous (watery) middle layer, and a lipid (oily) outer layer. In many people with dry eye, it's the lipid layer that's deficient — meaning tears evaporate too quickly. This is known as evaporative dry eye, and it accounts for the majority of dry eye cases.

• Perfluorohexyloctane (F6H8) is a semifluorinated alkane — a clear, oily liquid that is both lipophilic and slightly hydrophilic.
• When instilled, it spreads across the ocular surface and integrates with the existing lipid layer of the tear film.
• This stabilises the tear film, slowing evaporation and prolonging the time between blinks before discomfort returns.
• Because it contains no water, it does not dilute the aqueous layer or wash away natural tear components.

The result is longer-lasting relief compared to many aqueous-based drops, particularly for those whose dry eye is driven by meibomian gland dysfunction or a poor lipid layer.

Who Should Use EvoTears Eye Drops?

EvoTears is particularly well-suited to people with evaporative dry eye — the type caused by an unstable or deficient lipid layer rather than simply insufficient tear production. It's also a strong option for those who have reacted badly to preservatives in other eye drops, since it contains none whatsoever.

• Adults with chronic dry eye symptoms, including grittiness, burning, or watering eyes
• People who spend long hours in front of screens (digital eye strain)
• Contact lens wearers who experience end-of-day dryness (remove lenses before use)
• Those who have previously experienced irritation from preserved eye drops

It is not recommended for use in children unless specifically advised by an eye care professional. Always read the label before use.

How Do EvoTears Compare to Other Dry Eye Drops?

How Should EvoTears Eye Drops Be Stored?

Store your bottle of evotears eye drops below 25°C. Do not refrigerate — cold temperatures can affect the consistency of the perfluorohexyloctane formulation. Keep the bottle tightly closed when not in use and away from direct sunlight. Once opened, the bottle should be discarded after six months, even if product remains inside. This is a standard precaution for single-bottle ophthalmic preparations to prevent contamination.

If you wear contact lenses, always remove them before instilling the drops and wait at least 15 minutes before reinserting. This applies to both soft and rigid gas permeable lenses. If you're managing multiple eye conditions alongside dry eye, it's worth browsing our eye care range for complementary products.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is EvoTears and What Is It Used For?

EvoTears eye drops are a preservative-free ocular lubricant used to relieve the signs and symptoms of dry eye disease. The active ingredient, perfluorohexyloctane (F6H8), is a semifluorinated alkane that works by stabilising the lipid layer of the tear film — the outermost oily layer that prevents your tears from evaporating too quickly. Dry eye is a chronic condition that the NHS recognises as one of the most common eye complaints seen in primary care, with symptoms including burning, grittiness, redness, and intermittent blurred vision.

EvoTears is classified as a medical device rather than a medicinal product in the UK, and it is available without a prescription. It is intended for use in adults and is particularly effective for evaporative dry eye, which is the most prevalent subtype of the condition.

What Do You Need to Know Before Using EvoTears?

Before using EvoTears, make sure you are aware of the following contraindications and precautions:

• Do not use if you are allergic to perfluorohexyloctane or any other component of the formulation.
• Remove soft contact lenses before instilling the drops; wait at least 15 minutes before reinserting.
• Do not use in children unless specifically directed by an eye care professional.
• If you have an eye infection, eye injury, or have recently had eye surgery, consult your doctor before use.
• Do not touch the dropper tip to your eye, eyelid, or any surface to avoid contamination.
• If symptoms worsen or do not improve after a reasonable period of use, seek advice from your optometrist or GP.

Regarding drug interactions, no clinically significant interactions with other ophthalmic preparations have been identified. However, if you are using other eye drops or ointments alongside EvoTears, allow at least 15 minutes between applications and always apply EvoTears last if using an eye ointment.

• Other eye drops: apply at least 15 minutes before EvoTears
• Eye ointments: apply EvoTears first, then the ointment after 15 minutes

How Should You Use EvoTears?

Using EvoTears correctly ensures you get the most benefit from each drop. The technique is straightforward, but it's worth taking a moment to get it right — especially if you're new to using eye drops.

1. Wash your hands thoroughly with soap and water before handling the bottle.
2. Remove contact lenses if you wear them.
3. Tilt your head back slightly and look upward.
4. Gently pull down your lower eyelid to create a small pocket.
5. Hold the bottle above your eye and instil one drop into the pocket formed by the lower eyelid.
6. Close your eye gently and blink a few times to spread the drop across the ocular surface.
7. Repeat in the other eye if required.
8. Replace the cap immediately after use.

If you are managing other aspects of your eye health or general wellbeing alongside dry eye, you may find it helpful to explore our vitamins and supplements range, which includes omega-3 products that some research suggests may support tear film health.

What Are the Possible Side Effects of EvoTears?

EvoTears is generally very well tolerated, particularly because it contains no preservatives. That said, as with any ocular preparation, some people may experience mild effects after instillation. The NHS advises that you should stop using any eye drop and seek advice if you experience significant pain, vision changes, or signs of an allergic reaction.

Common side effects:

• Transient blurred vision immediately after instillation (usually clears within a few minutes)
• Mild, brief stinging or burning sensation upon application
• Temporary sensation of a foreign body in the eye

Less common side effects:

• Eye redness or mild irritation
• Watering of the eye shortly after use
• Eyelid discomfort

Serious allergic reactions (such as swelling of the face, lips, or throat, or severe eye pain) are rare but require immediate medical attention. Stop using the drops and contact your GP or call 111 if you experience anything unexpected or concerning.

How Should You Store EvoTears?

• Store below 25°C — do not refrigerate.
• Keep the bottle away from direct sunlight and heat sources.
• Keep the cap tightly closed when not in use.
• Discard the bottle 6 months after first opening, even if product remains.
• Keep out of the reach and sight of children.
• Do not use after the expiry date printed on the bottle and carton.

If you're looking for additional support for eye health or related conditions, our allergy and hay fever range includes antihistamine eye drops that may be useful if seasonal allergies are contributing to your eye discomfort.
