The retina contains the rods and cones. There are more rods than cones but is is more like 120 million rods to 5 million cones. Both are special cells that are photoreceptors. This means that they are sensitive to light. The cones are best for color vision but the rods are for low light. That is one reason why you don't see color in low light.

In countries that use the long scale (based on powers of a million) as used in Europe - one million:1 billion = 1012 ⇒ 1 billion ÷ 1 million = 1012 ÷ 106= 106In countries that use the short scale (based on powers of a thousand) as used in USA - one thousand:1 billion = 109 ⇒ 1 billion ÷ 1 million = 109 ÷ 106= 103
