Mask or glasses ?

When we walk it's said to be better wearing mask and glasses. It's because we protect from pollen and other polluted  air which put into and sink in our body and cause disorders.

I was trying to wear the mask and glasses but it made me so irritating with the cloud on my glasses by the breath.

It's somehow dangerous with the fogged glasses.

So do I have to give up glasses with UV cut?

I wonder if it would be strong sunshine and it gets warm, will breath haze appears on the glasses or not. It may be from the cold air?

I want glasses which doesn't mist by the breath.
