Quick answer
Choose Air Optix Night & Day Aqua if you need lenses approved for up to 30 nights of continuous wear. Choose Air Optix Hydraglyde if you want a daily-wear lens with high oxygen flow and all-day moisture.
Why the material difference matters
Both lenses are made from silicone hydrogel, which lets more oxygen reach your eyes than standard hydrogel lenses. But they are designed for different wear schedules, and that changes how they feel and perform.
Air Optix Hydraglyde uses an advanced hydrogel material that increases oxygen permeability up to five times compared to standard lenses. It also includes the AQUA moisture system to help prevent lens dry-out during the day.
Air Optix Night & Day Aqua is built for continuous wear, meaning you can sleep in them for up to 30 nights. That extended wear capability comes from a design that keeps your eyes healthy even when closed, but it may not deliver the same daytime moisture boost as Hydraglyde.
Comfort vs. extended wear: the real trade-off
The main trade-off is between daily moisture and overnight convenience. Hydraglyde focuses on keeping lenses hydrated through a full day of wear, which is ideal if you rarely sleep in your lenses. Night & Day Aqua is engineered for people who want to put lenses in and forget them for weeks, but you may need to use rewetting drops if your eyes feel dry during the day.
Both are available in a 6-pack, which is a practical size for a monthly replacement schedule. The 6-pack gives you a full month of daily wear or a complete cycle for extended wear, so you can stock up without overcommitting.
How to choose between them
- If you sleep in your lenses: Choose Air Optix Night & Day Aqua. It is designed for continuous wear, so you can keep them in for up to 30 nights without removing them.
- If you wear lenses only during the day: Choose Air Optix Hydraglyde. Its high oxygen permeability and AQUA moisture system help maintain comfort through a full day of wear.
- If you have an existing Night & Day prescription: You can order Air Optix Night & Day Aqua with that same prescription, so no extra eye exam is needed. Check your prescription and wear schedule before ordering to make sure you pick the right lens.
