To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These are great. They fit my big head well (I'm a 6ft male) and what I liked most is that the vents around the lenses really do keep the fog from building up - even when coming to a stop -I used them for cycling so results might be different for volleyball or something with less airflow. However other bobster goggle models were not effective at all at keeping the fog out. The other obvious benefit is that they fold up and come with a nice pouch. They are also very sturdy and lightweight.
I normally wear children's eyeglass frames because my face is narrow/small. These fit great. Just what I need to keep wind and debris out of my eyes. I wear these with contact lens though, not glasses.
