Bobster Bugeye Goggles,Black Frame/Clear Lens,one size

Do they form a good seal on your face? I'm looking for airtight (I know they have vents) but I want the seal around my eyes to be perfect.

the ad says amber at the top but description says clear and another ad says clear at the top and the description says amber. which is correct?

Are these good for airsoft?

Do these let dust in?
