Axis in the eyes refers to the orientation of the cylindrical component of astigmatism, measured in degrees. It is caused by an irregular shape of the cornea or lens, leading to uneven curvature that affects how light is focused on the retina. This irregularity can result from genetic factors, eye injuries, or certain eye conditions. Corrective lenses or surgery can help realign the light entering the eye to improve vision.
Earth's rotation on its axis causes day and night. Earth's revolution around the sun causes the seasons.
This tilt is what causes the seasons.
Earths rotation around its axis
Rotation of the planet on its axis causes night and day to happen on all planets. This rotation causes different parts of the planet to face the sun at different times, leading to periods of light (day) and darkness (night).

Earth's rotation on its axis causes day and night.
There are three main axes of rotation: the x-axis, y-axis, and z-axis. Each axis affects the movement of an object in different ways. For example, rotation around the x-axis causes the object to tilt forward or backward, rotation around the y-axis causes the object to tilt left or right, and rotation around the z-axis causes the object to spin in place. These rotations can change the orientation and direction of movement of the object.
Earth has four main motions: rotation, which causes day and night; revolution, which causes the annual seasons; precession, which causes a slow wobble in its axis; and nutation, which causes a slight variation in the tilt of its axis.
