In Maine, vision testing is required at the first renewal after driver's 40th birthday, then at every second renewal until age 62, and thereafter at every renewal. In Oregon, vision testing is required every 8 years for drivers 50 and older. In Illinois and New Hampshire, applicants 75 and older must take a road test.
Bottom line: When charged particles from the sun strike atoms in Earthâs atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
Contact encounters between gaseous particles in the atmosphere of the Earth and charged particles released from the atmosphere of the Sun result in the display of colors in the sky called the Northern Lights. The varying colors are as a result of specific types of gas particles that are bumping into each other. The scientific name for the Northern Lights are the Aurora Borealis. The aurora effect starts on the surface of the sun with solar activity, injecting a cloud of gas, scientifically known as a coronal mass ejection (CME).
