This is my personal favorite for night dry eye protection. It was developed by Eye Eco specifically to protect CPAP mask users from air leaks, but after its launch it quickly became my go-to product for a great many people for night dry eye protection with or without CPAP. 

Onyix/Quartz shields are not necessarily the products that provide maximal moisture, but they provide more than adequate moisture for a great many of us and they are small, user-friendly, easy to keep clean, low profile, and in general just very unobtrusive. So although I consider EyeSeals 4.0 superior in terms of protection offered (as well as some other advantages) I have stuck with Quartz for my personal use. 

For CPAP users, Onyix & Quartz should remain the first choice for most people except those with larger hat or orbit sizes who will want to go straight to the EyeSeals. 

I also find that many users like to rotate between products depending on time of year and the severity of their symptoms, so far example they might use Onyix/Quartz in the spring and summer months and then go back to Tranquileyes or EyeSeals 4.0 for the fall and winter when they are battling heated dry eye at night.

Suggested best uses

• First time dry eye shield users. This is the easiest one.
• Users who want something low profile and lightweight. This is a great way to block all drafts and trap a fair amount of moisture without wearing anything large, thick, heavy or foam lined.
• People who have skin reactions to the foam on Tranquileyes but for whom EyeSeals is too big or the material too heavy.
• CPAP/BiPAP users. I have high confidence of the compatibility of this product with almost all masks. I very rarely hear from anyone who cannot get it to work properly with their mask. (It is returnable/refundable if it doesn't work out for any reason - please see return policy.)

Limitations

• Sizing: Onyix & Quartz are  too small for some users, or may sit too close to their eyes if they have large orbits and/or very long eyelashes.
• Indentations: People who are prone to edema or who have very delicate, impressible skin around the eyes.

About the product:

Lightweight and comfortable, the product is made in the USA, and is 100% Latex Free.

Included in the kit:

• One Onyix™ silicone shield
• One microfiber travel sack

Usage and Care

What are Onyix & Quartz Silicone Shields used for?

Onyix and Quartz are used for dry eye protection at night and to protect CPAP/BiPAP mask users from air leaks.

Instructions for use

Gently clean face and eyelids to remove all dirt and make-up prior to using Onyix. Your mask is designed to keep moisture in and drafts out. The fit should be comfortable. Similar to finding your perfect shoe size. Not too tight and not too loose. To avoid tearing the mask, adjust the strap while mask is off the face. Once you find the perfect fit, the wrap is designed to stay put.

For increased moisture during wear, add a few drops of water inside of eyecups prior to wearing. The combination of moisture, an enclosed space and body heat creates a natural humidifier for the eyes.

Cleaning and care

To clean shield, wash with baby shampoo and rinse well with warm water. Dry with enclosed microfiber sack. Wash the head band as needed with cold water and mild soap, rinse well, squeeze out excess moisture and air dry.
