Yes, frosted glass diffuses light.

When light passes through frosted glass, the roughened or etched surface scatters the rays in multiple directions instead of allowing them to travel straight through as they would with clear glass. This scattering effect is called diffusion.

Key Effects of Frosted Glass on Light

1. Softens Light

• Light coming through appears softer and more even, reducing glare and harsh shadows.

2. Reduces Transparency

• You cannot clearly see objects through frosted glass, only blurred shapes and outlines. This makes it ideal for privacy.

3. Maintains Brightness

• Even though it diffuses, frosted glass still transmits a significant amount of light, keeping spaces bright while obscuring direct visibility.

Common Applications

• Bathroom windows and shower enclosures (privacy with light transmission).

• Office partitions (diffused lighting while reducing distraction).

• Light fixtures and lampshades (create a soft, ambient glow).

In short, frosted glass diffuses light by scattering it, giving softer illumination while maintaining brightness and privacy.
