This is called opacity. Materials that are opaque do not allow light to pass through them.
An object that lets no light pass through is called opaque. This means that light is unable to penetrate or pass through the object, resulting in the absence of transparency.
When light cannot pass through an object, it is called opacity. This means that the material does not allow light to travel through it and blocks the transmission of light.
Materials that some light can pass through are called translucent materials. These materials allow some light to pass through them, but not as clearly as transparent materials like glass.

The hole in the center of the iris through which light can pass is called the pupil.

Materials through which light cannot pass are called opaque materials. Examples include wood, metals, and thick plastics.
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
A material that only allows some light to pass through is called translucent. Unlike transparent materials, which allow all light to pass through, translucent materials diffuse the light, allowing only some of it to pass.
