The blindness fog is very clearly centered around the camera and not the player, and because the third-person camera's distance (4m) is further than the radius of the blindness fog (approx. 3.5m), the player can see blocks, entities outside of the radius of the blindness fog.
Steps to repro
Get the blindness effect
Select the third-person camera
Darkness effect might also be affected.

This is likely expected behavior. As @unknown stated previously, all other fog effects are calculated from the pre-projection position. this is easily showcased in when the player is submerged underwater but the camera is not. The water fog should techincally apply, but since you are not seeing from the player's view in third person it is not.

This works the same for any fog in the game and the reason for this is simple. The fog is calculated from the pre-projection position of the game. If they spend time fixing this bug, it means they have to rewrite the entire fog system.
