This effect is known as refraction. Refraction occurs due to the change in speed of light as it travels from one medium to another, causing it to change direction.
The light ray changes direction as it enters the glass block due to refraction, where the speed of light changes as it passes from one medium to another. This change in direction is caused by the bending of the light ray towards the normal of the surface at the point of entry.
When light is shined at a glass block, some of the light is transmitted through the block, some is reflected, and some is absorbed. The transmitted light changes its direction due to refraction as it passes through the glass block.
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
When light enters or leaves one medium for another (in your case glass to air);the speed of the light changes - AND (unless absolutely perpendicular) its path of direction changes.What you see in your eye is the light from an object - not the object itself.The simplest example is a looking glass ... contemplate yourself.
Light changes direction when it goes into a glass block and exits out because it refracts due to the change in medium.

Light changes direction when it exits a block of glass due to refraction, bending away from the normal (perpendicular) to the surface. The change in direction is caused by the change in speed of light as it moves from one medium to another with a different refractive index.
When light enters a glass block, it slows down and bends (refracts) due to the change in medium density. As the light passes through the block, it continues to bend until it reaches the other side, where it exits the block and resumes its original speed and direction.
Light that is polarized to be horizontal passes through horizontal polarizers. This separates it from the other directions of light, since normal white is not polarized and is in all directions.
If light rays do not enter a glass block, they will continue to travel in their original direction. The glass block will have no effect on the path of the light rays unless they actually enter the block.
It makes the block easier to lift by changing the direction of the force needed to lift it.
When a block is floating in a fluid, the net force in the vertical direction is zero. This is because the weight of the block is balanced by the buoyant force acting in the opposite direction, resulting in equilibrium.
