Can the umbrella protect against UV rays:

Sun umbrellas can block about 70 ultraviolet rays, but they cannot isolate reflected ultraviolet rays. If there is no anti-UV coated umbrella, you can also use a common sun umbrella. The black umbrella has a relatively better defense effect, followed by pink and goose yellow, while red has almost no UV protection.

2.UF value label

The UV protection umbrella should be marked with a sun protection index (UV mark), and the UPF value will be marked on the tag. When UPF = 30, UV filtration = 95%. When the UPF value = 50, the ultraviolet filter = 99.8% or more. But there are very few umbrellas that can really do UPF50, and it is not easy to buy. In general, in non-UV areas, an umbrella with a UPF of 30 is sufficient for daily sun protection.
