Tusa Paragon S allows for improved hydrodynamics and reduced water pressure on the face. But how do I deal with fogging on its anti-reflective lens?
Imran Hanafiah –
Thank you for sharing your experience with the Tusa Paragon S! Fogging on the anti-reflective lens can be a common issue. According to our product information, the UV 420 Lens Treatment helps reduce glare, but fogging may still occur. To minimize fogging, we recommend using a defogging spray or wipes on the mask before each dive. Additionally, you can try exhaling slowly through your nose while underwater to help prevent fogging. If the issue persists, please feel free to contact our customer support. Can you tell us more about how you’ve used the mask so far?
