What Hypochlorous Acid is used for
Hypochlorous Acid is a helpful medicine primarily used for maintaining good eyelid hygiene and managing certain eye surface conditions. It is particularly effective for:
- Blepharitis: This is a common condition where your eyelids become inflamed, often causing redness, itching, and crusty eyelashes.
- Meibomian Gland Dysfunction (MGD): MGD occurs when the tiny oil glands in your eyelids (meibomian glands) don’t work properly, leading to dry eyes.
- General Lid Hygiene: It helps keep your eyelids clean and free from excess bacteria.
- Pre-operative Lid Antisepsis: In some cases, it may be used to clean the eyelids before eye surgery to reduce the risk of infection.
By keeping your eyelids clean and reducing bacterial load, Hypochlorous Acid can significantly improve comfort and eye health for these conditions.
How it works
Hypochlorous Acid works by gently reducing the amount of bacteria present on your eyelid margins. Our eyelids naturally have some bacteria, but sometimes an overgrowth can lead to inflammation and conditions like blepharitis. By lowering this bacterial load, Hypochlorous Acid helps to calm inflammation and maintain a healthier environment for your eyes. It acts as a mild antiseptic, helping to clean the delicate skin of your eyelids without causing irritation, making it a suitable part of your daily lid hygiene routine.
How it’s used
Hypochlorous Acid is typically available as a lid spray or solution. Here’s how you generally use it:
- Application: You should spray or wipe your eyelids with the solution.
- Frequency: This is usually done once or twice a day, as advised by your eye care professional or as per the product instructions.
- Technique: Make sure your hands are clean before handling the product. If it’s a spray, close your eyes and spray directly onto your eyelids. If it’s a solution, you might apply it to a clean cotton pad or swab and then gently wipe along your eyelid margins, focusing on the base of your eyelashes.
- No Rinsing: Generally, you do not need to rinse it off after application.
Always follow the specific instructions provided with your product and by your eye doctor for the best results and to ensure proper hygiene.
Always follow your ophthalmologist’s exact instructions.

Good to know
Available without prescription, but this is not a substitute for an eye examination. If redness, pain, discharge or blurred vision persists for more than a day or two, see an eye doctor rather than continuing drops on your own.
Precautions & side effects
Hypochlorous Acid is generally well tolerated and considered a safe product for daily lid hygiene. However, it’s important to keep a few things in mind:
- Well Tolerated: Most people find this product very gentle and do not experience significant side effects.
- Part of Daily Lid Hygiene: It is designed to be a regular part of your eyelid cleaning routine.
- Not a Substitute for Eye Examination: While available without a prescription, using Hypochlorous Acid is not a substitute for a comprehensive eye examination by an eye doctor.
- When to See a Doctor: If you experience persistent redness, pain, discharge from your eye, or blurred vision for more than a day or two, it is crucial to stop self-treating and consult an eye doctor immediately. Do not continue using the spray on your own in such situations. Your eye doctor can diagnose the underlying issue and recommend appropriate treatment.
Always use the product as directed and consult your eye care professional if you have any concerns or if your symptoms worsen or do not improve.
Understanding Eyelid Health and Common Conditions
Our eyes are precious, and the health of our eyelids plays a crucial role in protecting them and keeping them comfortable. The eyelids act like a shield, protecting the delicate surface of the eye from dust, debris, and injury. They also help spread tears across the eye with every blink, keeping the eye moist and clear. However, sometimes our eyelids can become a source of discomfort due to common conditions like blepharitis and meibomian gland dysfunction (MGD).
Blepharitis is a very common condition where the edges of your eyelids become inflamed. This can lead to symptoms such as red, itchy, and swollen eyelids, a gritty sensation in the eyes, and crusty eyelashes, especially in the morning. It often happens when tiny oil glands near the base of your eyelashes get clogged or irritated, or due to an overgrowth of bacteria that normally live on our skin. While usually not serious, blepharitis can be persistent and uncomfortable, affecting your daily life.
Meibomian Gland Dysfunction (MGD) is closely related to blepharitis and is a leading cause of dry eye syndrome. The meibomian glands are tiny glands located along the edges of your eyelids that produce the oily layer of your tears. This oil prevents your tears from evaporating too quickly. When these glands don’t function properly – perhaps they are blocked or the oil they produce is too thick – it can lead to an unstable tear film, causing dry, irritated, and uncomfortable eyes. Both blepharitis and MGD often require consistent lid hygiene to manage symptoms effectively.
Maintaining good eyelid hygiene is fundamental to preventing and managing these conditions. Just like we brush our teeth daily, cleaning our eyelids regularly can make a significant difference in eye comfort and health.
Correctly Using Eye Medicines and Maintaining Hygiene
When using any eye medicine, especially lid sprays or solutions, proper technique and hygiene are paramount to ensure effectiveness and prevent contamination. Always start by washing your hands thoroughly with soap and water. This simple step is critical to avoid introducing germs to your eyes or the product.
For a lid spray, close your eyes gently and hold the bottle at the recommended distance (usually a few inches) before spraying directly onto your closed eyelids. If it’s a solution, you might apply a small amount to a clean, lint-free cotton pad or swab. Then, with your eyes closed, gently wipe along the base of your eyelashes and the eyelid margins. Be careful not to touch the tip of the bottle or applicator to your eye or any other surface, as this can contaminate the product. After application, you typically do not need to rinse off Hypochlorous Acid, allowing it to work on your eyelids.
Storage is also important. Always keep your lid spray or solution in a cool, dry place, away from direct sunlight, and out of reach of children. Check the expiry date on the packaging and discard any expired product. Never share your eye medicines with anyone else, as this can spread infections.
When to Seek Professional Help
While Hypochlorous Acid is an excellent tool for daily lid hygiene and managing mild symptoms, it’s important to understand its role and when to seek professional medical advice. It is available over-the-counter, meaning you don’t need a prescription to buy it. However, this does not mean it’s a substitute for a proper eye examination by an ophthalmologist or optometrist. Eye conditions can sometimes be more complex than they appear, and a professional diagnosis is essential for effective treatment.
You should always consult an eye doctor if you experience any of the following symptoms: persistent eye redness, significant eye pain, unusual discharge from your eye, or any sudden or worsening blurred vision. If these symptoms last for more than a day or two, or if your current symptoms do not improve with regular use of Hypochlorous Acid, it’s a clear sign that you need a professional evaluation. Continuing to use over-the-counter products on your own when symptoms are severe or persistent can delay proper diagnosis and treatment of potentially more serious underlying conditions. Your eye doctor can provide an accurate diagnosis, rule out other conditions, and recommend the most appropriate course of action for your specific eye health needs.
