Why do people get old?  And why does the eyes get older first?

Aging is a broad term that refers to each part of the body getting old. But each part of the body gets old in its own way. Your eye has two main parts that are necessary for vision, the front which is a lens for focusing and adjusting the amount of light and the back which is like the film in a 35mm camera to receive the light and translate it into a message for the brain. When we age, for the most part, the changes to the front of the eye are the most noticeable. The front of the eye has a lens which is attached to little muscles which bend it so you can focus on things far away and things up close like the lens of a camera. This lens is a big piece of transparent protein that is created during development and doesn't really change much for the rest of your life, so as you get older, day to day, you bend the lens to read, and then to see far away and everything in between and it works, but because it's not perfect it gets gradually stiffer as you get older, sometimes it will get cloudy as in cataracts and sometimes the muscles that bend it will get weak, all contributing to the perceived aging of the eye.

All 3 of the previous answers aren't quite right.  The condition you're looking for is called presbyopia and it happens to nearly everybody.  It happens when the muscles in your eye aren't able to focus up close anymore.  (In a way, they just kind of wear out with age.)  Reading glasses, bifocals, progressive lenses, bifocal contact lenses, and monovision are all good options you can try.

Your question is "Why are some people eyes whiter than others?"\nThe answer: Cos some people take care of them much better than others, or are not stressing them that much in comparison to the red eyed ones.\nIt cud also be genetic.

seems to be the natural order of things... the beautiful, young, intelligent person seems to die at 20 of some freak tumor or something, while the person filled with hate and ignorance lives until he is 109... \n\ncockroaches will never die, while the most beautiful flowers wither away the fastest...

It's genetic in most people.\n\nThe second main cause is a change in melanin levels in one eye, this can be because of illness or trauma to the head.\n\nFor others a trauma to the head can jolt the blood vessels in the eye causing a change in colour

Amazing the natural selection process.  Originating form the times when we were living lifestyles more exposed to the weather, they help keep foreign materials from falling in our eyes.  Tree leaves, dust, rain, etc, coming from above us.\n\nTake a look at some of the earlier life forms, Neanderthals for example. see how thick their eye-brows, how deep their eye sockets are.

The older I get, the more thankful that I am getting older. Why stop the aging process? Life does get better with age.

No life form "knew" that there was any need to develop eyes. At some point after life first appeared on Earth, an accidental mutation in some organism caused certain nerve endings to become light sensitive. This new trait increased the survival probability for this species which means it produced more copies of itself than other species without the mutation. Over a very long period of time, this first primitive "eye" mutated even more, gradually evolving into the modern eye.

They live by example. It depends sometimes on their eyesight. If they need glasses to see afar off and reading too they can't wear contacts because they don't make them like that. They need glasses with bifocals especially when they become presbiopic (2nd sight) around 40. They can see good afar off but at near their vision is bad- bifocal time. Contacts are only for distance vision, not near.

it depends on the person.\nbigger people have more hair\nand old people lose their hair.

I did when I was a kid, but now I'm 38 and know better. It doesn't get good 'till you hit 30. I think our idea of "old" tends to change the older we get.

Clearly people are designed to live MUCH longer than they do. Trees live to be over a thousand years old. Turtles can get older than people. Our brains only use a smidgen of their overall capacity before we grow old and die......something is wrong. \n\nHumanity was originally designed and placed to enjoy living, and all the experiances, arts, sciences, work and play that goes along with that. That orignal purpose WILL be realized, once the great issue of universal sovereignty is proven and established. \n\nHow can we as imperfect human decendants of sinners even contemplate what that experience will be like after that great day? People then will not be the way they are now. They will not be bored......ever!

Are you talking about the eye surgery. I think the age that they will start performing is 21. Your eyes have to stop changing and you have to be approved by your doctor first, to see if your eyes will work in this type of surgery.

Because adults have more responsibilities than children.  When you get really old, you have less responsibilities and you sleep more.  Interesting.

This is what I found about eye color changes.  For complete articles see the web sites in sources below.\n\n"A surprising new study found that 10% to 15% of whites undergo changes in eye color during adolescence and adulthood, according to a report in the Archives of Ophthalmology."\n\n"The mechanisms that control these changes in iris color remain unknown. But researchers believe that it may be due to changes in production from melanocytes, cells found in the hair, skin and the eye that make melanin, a black or brown pigment.\n\nMore study is needed to confirm that the eye change is true age-related change in color and not due to illness or a flaw in the study. One report has suggested that macular degeneration, the leading cause of blindness in older adults, can be accompanied with a lightening of eye color with age, the authors noted."\n\n"Ask a doctor to examine your eyes if you notice a slow loss of color. The change could be due to Fuch’s heterochromic iridocyclitis, Horner’s Syndrome, and pigmentary glaucoma."

People have a genetic coding that basically extends life to approx 125 years old.  Our genetic make up accounts for approximately 30% of our life expectancy.  Environment and habits accounts for the other 70%.  Our bodies are constantly breaking down and our body does not have the ability to repair these breakdown indefinately.  Once our body loses the ability to repair our breakdowns we begin to see signs of aging.  Once the process begins we are unable to effectively stop it.  Maybe with advances of science and gene therapy we can extend our ability to repair but until then you are kind of stuck with your genetic make up.
