Blindness is the inability to see anything. Some people are called blind, even though they can see a little bit. This is because they cannot see clearly, but only see fuzzy shapes or colours.
In modern countries, few young people are blind. In all the world, blindness is mostly caused by malnutrition and diseases of old people, like cataracts and trachoma. People can become blind because of diseases or accidents, but sometimes people are born blind.
Some people are color blind, which means they can see, but cannot tell certain colours apart.

A star is a big ball of gas in outer space that is held together with gravity. The star nearest to Earth is the Sun. Most of the energy on Earth comes from it. We can see other stars in the night sky when the Sun goes down. They are made mostly of hydrogen and a little bit of helium plus other elements. The sun is such a star.
