Hylo-Dual typically refers to one of two popular products featuring distinct green packaging or brand identities: HYLO® standard lubricating eye drops (often distinguished by its bright green bottle accent and box) or Hylo Athletics sustainable footwear. 
 
 
1. HYLO® Lubricating Eye Drops (Standard Green Box)
 
The core product in the CandorVision HYLO Family uses green branding to denote its formula for mild to moderate dry eye relief. 
 
The Formula: It contains 1 mg/mL Sodium Hyaluronate, a naturally occurring lubricant that forms a stable, long-lasting moisture film on the eye. 
The Bottle: It features Germany's specialized COMOD airless pump system. This design guarantees the solution stays completely sterile for 6 months after opening without requiring any chemical preservatives or phosphates. 
Compatibility: It is entirely safe to use alongside contact lenses and is well-tolerated for long-term recovery, including post-surgery healing. 
Note: If you are looking for something lighter, the brand also makes HYLO FRESH® (often highlighted in light green) for minor irritation or environmental redness.
