Why can we see clearly underwater with goggles but not with our bare eyes?

Also, do fish have some sort of eye-covering membrane or how do they circumvent this problem?

Your eyes are trained to deal with a surrounding medium with a low refractive index, like air.  Water has a high refractive index, which makes the light bend in ways your eyes aren't expecting.  

Fish eyes are made for seeing while immersed in water, so they'd have the same problem in air that we do in water.
