By something called reflection.
To change the direction of a light beam, you can use mirrors or lenses to reflect or refract the light in the desired direction. Adjusting the angle of the mirror or lens will change the direction of the light beam. Alternatively, you can physically move the light source or the object the light is reflecting off of to change the direction of the beam.
No, a laser beam travels in a straight line through air unless it reflects off a surface. The direction of a laser beam can be altered by using mirrors or prisms, but it does not change direction on its own in mid-air.
The beam of light entering your eye can change direction at the cornea, the lens, and the vitreous body. These structures help focus the light onto the retina at the back of the eye, where the images are formed.
Parabolic
Lasers can use reflection by bouncing the light back and forth between two mirrors within the laser cavity. This process amplifies the light through stimulated emission, resulting in a coherent and powerful laser beam. The mirrors help to maintain the direction and coherence of the laser beam.

Refraction.
the light 'beam' (if you like) will slightly change direction this is bending light, light only travels in straight lines but due to the shape of the glass it changes direction when the beam exits the glass its should go back to its shape of ligh beam .

Because it slows down when entering water.
Parabolic mirrors are typically used in search lights. These mirrors are designed to reflect light rays in a parallel direction, allowing the search light to project a strong beam over a long distance.
Car headlights use concave mirrors to focus and direct light beams in a specific direction. The shape of the concave mirror helps to gather and reflect more light outward, increasing the brightness and distance of the light beam. This design improves visibility for the driver and helps illuminate the road ahead.
When a beam of light hits water, it can undergo refraction, which causes it to change direction due to the change in speed between air and water. Some of the light may also be reflected off the surface of the water.
