Alcon TOTAL30 Contact Lenses

The "forget you're wearing it" comfort of a water gradient lens — now for a full month. TOTAL30 by Alcon is the first and only monthly replacement lens with a water gradient design, engineered to feel just as fresh on day 30 as it does on day 1.

Water Gradient Technology — like a lens, feels like a tear

Most contact lenses have the same material from core to surface. TOTAL30 doesn't. The lehfilcon A material transitions from a breathable silicone hydrogel core with 55% water to an ultra-soft, hydrophilic outer layer where the water content approaches nearly 100% at the outermost surface that touches your eye and lid. What touches your eye isn't really plastic at all — it's a cushion of water.

CELLIGENT Technology — a biomimetic surface for a clean lens

CELLIGENT Technology is a biomimetic chemistry inspired by the glycocalyx of the cornea itself. Under an electron microscope, the surface shows fine nano-fibre protrusions similar to those on the natural corneal surface. This layer helps the lens selectively attract small water molecules while resisting much larger ones — including lipid deposits and bacteria. The clever part: this smooth, water-rich surface holds up for the full 30 days of wear.

High breathability for healthy eyes

The silicone hydrogel core delivers a Dk/t of 154 — one of the highest oxygen transmissibility values among monthly reusable lenses. Plenty of oxygen reaches the cornea throughout the day, helping keep your eyes white, bright and feeling healthy.

Class 1 UV protection

TOTAL30 includes a Class 1 UV-blocking filter — the highest UV classification available in contact lenses — absorbing more than 99% of UVB and over 90% of UVA rays that reach the lens. Useful extra protection for everyday outdoor light, though lenses don't cover the whole eye and aren't a substitute for UV-protective sunglasses.

Exceptionally low surface friction

The ultra-soft water-rich surface gives the lens very low friction against the lid and the eye. Less rubbing means less irritation and less end-of-day fatigue — right through to day 30.

Easy to handle, easy to wear

A light blue handling tint makes each lens easy to spot in the blister and easy to handle during insertion and removal — without affecting your eye colour or your vision.

A simple monthly routine

Wear them through the day and replace every month, with nightly cleaning and storage in fresh solution.

Contact lenses are medical devices. Wear them only as directed by your eye-care professional, keep to the recommended monthly replacement and hygiene routine, and make sure you have a valid contact lens fitting. The UV filter in contact lenses is not a substitute for UV-protective sunglasses or goggles.
