Swim goggle questions

[HillSlugger]

2. What is your opinion on colored/shaded goggles as opposed to clear. My current ones are clear. I think the colored/shaded ones look way better, can you see well through them in the pool? Do they make it darker, or do they provide more contrast?

Thanks!

I bought gray tinted ones figuring they'd be useful for my open water swim tri (my eyes are especially sensitive to bright light). Sure, they make it darker inside, but I can see very well with them in the pool. I don't know if they improve the contrast.
