Lens technology, explained

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.

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.

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 - key for comfort, especially in long-hour wear.

Hyaluronic acid (HA) is a powerful moisturiser that binds water molecules, keeping the lens surface hydrated. Clearlii lenses release HA gradually through the day, reducing dryness and maintaining comfort in screen-heavy or dry environments.

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.

Yes. Select Clearlii designs include UV and blue-light filters that protect against harmful rays while still allowing beneficial light to pass through - particularly helpful for wearers with high screen exposure.

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.

Unless specifically prescribed, no. Even with silicone hydrogel, sleeping in lenses reduces oxygen availability and increases infection risk. Always follow your optician's recommendations.

Your optician will assess your prescription, eye health and lifestyle. Some eyes need daily freshness, while others benefit from the durability of monthlies.

Daily disposables (e.g. Clearlii Daily, Clearlii Vitamin) give you a fresh, sterile lens every morning, ideal for new or occasional wearers. Monthly lenses (e.g. Clearlii Monthly, Clearlii Monthly Advanced) are reusable for up to 30 days with proper care, and are more cost-effective for regular wearers.

No. Simply discard them after use.

Never. Tap water may contain microbes that can lead to serious eye infections. Always use sterile lens solution.

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 to 3 months.

Check that the lens is not inside-out, damaged or past its replacement date. If discomfort persists, remove the lens and consult your optician.

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 regular breaks and hydration are also key.

No. The anatomy of the eye prevents this. A lens can sometimes move under the eyelid but is easily removed with proper technique.

Yes. Proper fitting ensures lenses match your eye's curvature, diameter and tear profile. Poorly fitted lenses may cause discomfort or even damage.

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.
