The axis number on your prescription tells your optician in which direction they must position any cylindrical power in your lenses (required for people with astigmatism). This number shows the orientation or angle in degrees from 1 to 180. The number 90 means vertical position and 180 horizontal. A higher number for the axis does not mean that your prescription is stronger - it simply describes the position of the astigmatism.
This is what is known axial tilt, where a planetâs vertical axis is tilted a certain degree towards the ecliptic of the object it orbits (in this case, the Sun). Such a tilt results in there being a difference in how much sunlight reaches a given point on the surface during the course of a year. In the case of Earth, the axis is tilted towards the ecliptic of the Sun at approximately 23.44Â° (or 23.439281Â° to be exact). 1  Earthâs axis points north to Polaris, the northern hemisphereâs North Star, and south to dim Sigma Octantis. 2  Artistâs rendition of the Earthâs rotation and the precession of the Equinoxes.
