Is this significantly less effective than a normal surgical mask because of the large gaps?
- stellar678 7y agoGiven that it covers the eyes, seems better than a surgical mask. Surgical masks aren't really filtering anything microscopic that's floating in the air, just blocking spit and other macro stuff.
- jhweoiru 7y agoWrong. Surgical masks block about 75% of small particles, N95 respirators block 95%+.
- chadlavi 7y agothis isn't a mask replacement, this is a shield to protect from larger aspirated drops when giving an infected individual medical care. It's worn over a mask.
- jhweoiru 7y agoThis is for the eyes. You still need a mask.
- DanBC 7y agoYou wear this and either a surgical mask or an FFP3 mask. This stops stuff going into your eyes. You must not ignore the ocular route. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30313-5/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6... This will me more useful to healthcare professionals (or family carers) working in close proximity to patients (or family) who may have covid-19, especially if those patients are coughing or the HCPs are performing AGP - aerosol generating procedures.
