Except for CR-39 (1.50), all plastics lenses (e.g. high index, poly, trivex) block 100% of UVA and UVB light, so any UV-blocking coating is unnecessary, https://www.eyecarebusiness.com/issues/2012/august-2012/a-lo...
It's also good for your eyes to have a small amount of UV exposure, at least a few mins per day, so take off your glasses for short periods when outside. Everyone who does not wear glasses and is not wearing sunglasses 100% of the time is receiving some UV exposure.
