VogueVogue Eyewear Women's Vo5352sf Low Bridge Fit Square Sunglasses

I have a wider head but an asian face and nose so I need glasses with a smaller bridge. The bridge part is great, however, the arms are so loose, they don't feel like they will stay on my head. The arms aren't even symmetrical - when you look at them straight on, they are budging outwards. I need a pair I can have prescription lenses put into, so this won't work, since with the heavier script lenses, and the loose arms, it will most certainly fall forward and cause all kinds of pressure.
