Why is frosted glass often used for bathroom windows instead of clear glass or a solid wall?

Clear glass does not provide any privacy, because obviously you can see through it. A solid wall does not allow any light in. Therefore, frosted glass is a good solution to both problems because it allows light to shine through without compromising privacy, because you can't see through it clearly.Why is frosted glass often used for bathroom windows instead of clear glass or a solid wall?
it lets light in and you can't watch people throught the glass


My Gawd can you ask a more mundane obvious QWhy is frosted glass often used for bathroom windows instead of clear glass or a solid wall?
Frosted glass gives more privacy than clear glass and a solid wall doesn't let any let in, so frosted glass is a happy medium: light and privacy.
The frosted glass is more translucent than transparent, discouraging peeping toms. The frosted glass lets a lot of light in, which is better than a wall.
