It might be bad weather, or night time, the mist is much thicker during these times. Sleep or wait out the poor weather, like every other biome.

As above, or learn a small amount of patience.

"The mist is always present are never subsides."

See the first answer. It actually does subside quite a lot during the day.

Simply not true. The wisplight clears just enough to see your own head and feet in clear weather during the daytime. I'm not sure how you people getting actual clearance are getting a completely different experience.
