Do volk lenses block uv? I know that you can buy the yellow patient
comfort filter for a lot of the lenses which their website states
blocks all wavelengths shorter than 490nm but is the basic lens zero uv
transmission?

The reason I ask is that my pre reg has been told that if she brings a
uv lens to the exams it must be uv filtered. I cant imagine so many
people owning the yellow filter.

Thanks
