How do you know which goggle are good to get for swimming?

I bought a pair of Speedo Air Seals and they always seem to leak water, but I have an older pair of goggles which stop the water from leaking but they end up giving me racoon eyes after. If the goggles are too tight, is it bad for my eyes? Some advice on getting goggles would help…like what type, I know they have to suction on a little for them to fit your face.

Thanks.

What are the BEST goggles out there for swimming?

I want the best goggles out there. What brand and model is it? I want something clear if possible but performance is the main goal. I dont want it to leak water, fog up, have a bad string or leave red circles around my eyes when i take em off. What do you reccomend?
