Why is visible light important?

Answer 1

Human eyes, and the eyes of other creatures, work on the visible light spectrum. Humans are highly dependent on their eyes. Some creatures have very primitive eyes compared with humans, and they must rely on other senses.

Answer 2

Visible light is important, especially to us, because it is intimately involved in

the common process of helping us to see things. Maybe if we did not have it

we could find other ways of seeing stuff, but right now we have gotten used

to it so we depend on it as it is hard for us to live our life without it.

These are some of the important things which we could not do without visible light,

and there are a whole lot more of them:

-- see the stop signs while driving

-- read the screen on our smartphone

-- find our way to school

-- figure out the channel numbers on the TV

-- cross the street safely

-- get some enjoyment out of movies

-- appreciate stylish clothes and sunglasses

-- recognize our parents when they are right there

-- eat our food without making a mess

-- understand our IMs when we are on line and on Facebook

-- know which sneakers look better

-- catch a fly-ball

-- play cards

-- pay for things with paper money

-- cook without getting cut or burned

-- read any good books

-- feed our pets and take them for a walk

Visible light is very important and I am glad that we have it and I am sorry

for the people who are blind and who can not see our visible light.
