●Do not rub the lenses of your mask!!
Generally, masks with glass lenses are rubbed with toothpaste to remove the oil film before use, but UMMY's Streamline, Beach, and Reef have plastic lenses, so rubbing them can scratch the lenses, making it difficult to see, or even cause the lenses to become cloudy. Please never rub the lenses. Use them as is without rubbing them.
●Plastic lenses are easily scratched, so please handle them with care!
The aforementioned plastic lenses are characterized by being very light compared to glass lenses, and because they are curved lenses to reduce water resistance, they have excellent design. On the other hand, because they are made of plastic, they are very susceptible to scratches. Even just touching the lens directly with your fingers can cause scratches. Be sure to store them in a case, read the examples below, and handle them with care.
✅Lenses that are easily scratched
- Rubbing the lens
Touch the lens with your fingers
・Wipe the lens with a dry cloth or tissue.
- Using the camera in very shallow waters near the beach (small pebbles are flying around and the lens is easily scratched)
・Placing the mask directly on the beach (in direct contact with sand)
- Scenes where masks and multiple pieces of equipment are placed in a bag or similar and come into contact with each other
- Uses a stick-type, direct-apply anti-fog product
●No anti-fog required! (Streamline and Reef only)
Streamline and Reef are anti-fog treated, so anti-fog is not necessary. If the inner lens of the mask becomes slippery when it gets wet, this is due to the coating and is not abnormal. (Please do not touch the lens directly.)
In rare cases, using a mild detergent or a strong anti-fog agent made overseas may cause the anti-fog coating to peel off. Please refrain from using detergents or strong anti-fog agents.
The effectiveness of the anti-fog coating may decrease with the frequency of use of the mask. In that case, please use an anti-fog product.
* We cannot provide compensation if the lens is scratched or the anti-fog coating is peeled off due to customer carelessness.
*We do not accept exchange of lenses only.
