Support & FAQs – Lens Technology
Answers to your technical questions, from materials to maintenance.
At Clearlii, we believe that understanding your lenses helps you wear them with confidence. Whether you’re curious about materials, hydration, or how to care for your lenses, this FAQ brings together expert answers to the most common questions about our technology.
Materials & design
Q: What makes Clearlii lenses different from standard contact lenses?
A: Clearlii lenses combine premium materials like silicone hydrogel with innovations such as hyaluronic acid reservoirs, vitamin enrichment, UV/blue-light filters, and Soft-Comfort Edge design. Together, these features support oxygen flow, hydration, and all-day comfort.
Q: What is silicone hydrogel, and why is it important?
A: Silicone hydrogel is a material that allows up to five times more oxygen to pass through to your cornea compared to traditional hydrogel. More oxygen means healthier, brighter eyes with reduced redness.
Q: Why does edge design matter?
A: The edge of a lens interacts with your eyelid at every blink. Clearlii’s Soft-Comfort Edge ensures a smooth profile, minimising friction and supporting natural tear flow. This is key for comfort, especially in long-hour wear.
Hydration & comfort
Q: How does hyaluronic acid improve comfort?
A: Hyaluronic acid (HA) is a powerful moisturiser that binds water molecules, keeping the lens surface hydrated. Clearlii lenses release HA gradually throughout the day, reducing dryness and maintaining comfort during screen-heavy or dry environments.
Q: What role does vitamin enrichment play?
A: Clearlii Vitamin lenses contain micro-encapsulated vitamin E, an antioxidant that combats oxidative stress from UV light, pollution, and digital devices. This helps reduce the sensation of fatigue and irritation.
Q: Do Clearlii lenses protect against blue light?
A: Yes. Select Clearlii designs include UV and blue-light filters that protect against harmful rays while still allowing beneficial light to pass through. This is particularly helpful for wearers with high screen exposure.
Oxygen & health
Q: Why does oxygen matter for my eyes?
A: The cornea has no blood vessels, so it relies on oxygen from the air. Low oxygen (hypoxia) can cause redness, swelling, and long-term complications. Silicone hydrogel ensures optimal oxygen supply, even in thicker lenses for higher prescriptions.
Q: Can I sleep in Clearlii lenses?
A: Unless specifically prescribed, no. Even with silicone hydrogel, sleeping in lenses reduces oxygen availability and increases infection risk. Always follow your optician’s recommendations.
Replacement schedules
Q: What’s the difference between daily and monthly lenses?
A:
-
Daily disposables (e.g. Clearlii Daily, Clearlii Vitamin): a fresh, sterile lens every morning. Convenient, hygienic, and ideal for new or occasional wearers.
-
Monthly lenses (e.g. Clearlii Monthly, Clearlii Monthly Advanced): reusable for up to 30 days, provided you clean and store them properly. More cost-effective and eco-friendly for regular wearers.
Q: How do I know which type is best for me?
A: Your optician will assess your prescription, eye health, and lifestyle. Some eyes need daily freshness, while others benefit from the durability of monthlies.
Maintenance & care
Q: How do I clean and store monthly lenses?
A:
-
Wash and dry your hands.
-
Place the lens in your palm with a few drops of Clearlii Multi-Purpose Solution.
-
Rub gently for 20 seconds in circular motions.
-
Rinse and store in a clean case filled with fresh solution.
-
Replace the case every 1–3 months.
Q: Do daily disposables require cleaning?
A: No. Simply discard after use.
Q: Can I rinse lenses with tap water?
A: Never. Tap water may contain microbes that can lead to serious eye infections. Always use sterile lens solution.
Troubleshooting
Q: What if my lenses feel uncomfortable?
A: Check that the lens is not inside-out, damaged, or past its replacement date. If discomfort persists, remove the lens and consult your optician.
Q: Why do my eyes feel dry with lenses?
A: Causes may include reduced blinking (common with screen use), dry environments, or overworn lenses. Clearlii’s HA and vitamin-enriched designs help reduce dryness, but habits like regular breaks and hydration are also key.
Q: Can a lens get lost behind my eye?
A: No. The anatomy of the eye prevents this. A lens can sometimes move under the eyelid but is easily removed with proper technique.
Professional fitting & safety
Q: Do I really need a professional fitting?
A: Yes. Proper fitting ensures lenses match your eye’s curvature, diameter, and tear profile. Poorly fitted lenses may cause discomfort or even damage.
Q: How often should I see my optician?
A: At least once a year, or more frequently if you experience issues. Regular check-ups keep your prescription up to date and ensure long-term eye health.
