Can depend on specific types of glare and water (river, lake, sea) whether it helps or hinders depth perception - become familiar and have alternate options for when you do and do not want polarized lenses.
On Water Considerations
Use Croakies or some strap to prevent loss
Fogging, may be a bigger problem in cold weather
Some glasses are advertised as having designs that reduce this - seems to help with some of them
Use same methods that divers use with masks - saliva, soap, or commercial anti-fog solution such as Op-Drops.
Droplets - keep front of lenses clear of puddles with something like RainX for plastic - works on GoPros too. Reapply regularly.
