Most contact lenses come with a hard rule: take them out before bed. Air Optix Night & Day is one of the few exceptions. It's FDA-approved for up to 30 nights of continuous wear, meaning you can sleep, nap, and go about your life without removing the lens, if your eye doctor determines you're a good candidate.

What makes overnight wear possible
The lens is made from lotrafilcon A, a fluorosilicone hydrogel material with a genuinely high oxygen transmissibility rating of 175 Dk/t. In plain terms, this lens lets up to 6 times more oxygen reach your cornea compared to standard soft contacts. That matters enormously for overnight wear specifically, since your cornea needs a steady oxygen supply even while your eyes are closed, and this is exactly the kind of material that makes extended wear reasonably safe for a good portion of people.
It's worth being upfront here: not everyone can wear these for the full 30 nights. Alcon's own data shows roughly 80% of wearers can manage extended wear, and about two-thirds make it through the full 30-night stretch. Sleeping in any contact lens does raise the risk of complications like corneal infection compared to daily wear, so this is very much a conversation to have with your eye doctor rather than a decision to make solo.

Staying clean over a long wear cycle
SmartShield Technology adds an ultra-thin protective layer over the lens surface, which helps limit the buildup of lipids and debris that would otherwise accumulate over such a long, continuous wear period. It also helps tears spread more evenly across the lens, which supports moisture retention even when you're not blinking away (like, say, while you're asleep).

Fit details
The lens comes in two base curves, 8.4mm and 8.6mm, with a 13.8mm diameter, plus a light blue handling tint. Water content sits at 24%, which is lower than a lot of other lenses, but that's intentional here — the oxygen permeability in this material comes from the silicone content rather than water, which is part of what makes the extended wear approval possible in the first place.

Good fit if you:

• Want the flexibility of true overnight or multi-day continuous wear
• Have a busy or unpredictable schedule and want fewer daily lens routines
• Are approved by your eye doctor for extended wear and want one of the most oxygen-permeable options available
• Understand and accept the added risks that come with sleeping in contacts
