Is Blocc Available on Ebay, Etsy, Lazada, or Shopee?
No. The authentic Blocc is not listed on e-commerce sites other than our official Amazon Store. Similar-looking variations distort and harm your vision and cause severe dizziness due to poor engineering.
Does Blocc fog up?
Blocc is coated with anti-fog and anti-scratch coatings to mitigate fogging and minor scratches on the surface (Please note that the coatings may wear off overtime).
Can Blocc replace a face mask?
No, Blocc cannot replace a face mask. The CDC does not recommend using face shields or goggles as a substitute for masks. We advise that you wear Blocc in addition to a face mask for full protection.
Can I wear prescription glasses with Blocc?
You can wear most glasses together with Blocc.
Can I adjust the nosepiece?
Yes. The nosepiece is easy to bend, as it is made of impact-resistant polycarbonate. You can adjust it freely to fit the shape of your nose.
Can I use alcohol or lysol wipes to clean Blocc?
No, Blocc should be rinsed with dish soap and warm water only.
What is Blocc made of?
Blocc is made of impact-resistant polycarbonate; the same material used to manufacture medical and military-grade accessories such as protective goggles. It also makes Blocc a lightweight, reusable face shield that provides glass-like optical clarity and visibility (Fun fact: NASA’s astronaut helmet for the Apollo moon landing in 1969 was also made from polycarbonate).
