The eyes remain the same size from birth till death?

yes i agree with you, also your eyes do not rotate with your head, try looking at your eyes in a mirror and tilt your head, what would happen if you tilted round 360 degrees :o  POP

The Genetics of Human Eye Color\nCan a baby's eye color be predicted using the eye color of the parents, grandparents and siblings?\nEye color is a physical trait that is genetically determined. A favorite pastime for many expectant parents is documenting the eye color of grandparents and extended family members to attempt to predict the eye color of their baby. Any discussion of the inheritance of eye color, requires a review of genetics. In basic terms, eye color is determined by the amount of a pigment called melanin that is in the iris of the eye. Brown eyes have lots of pigment, blue eyes very little. The amount of pigment is determined by a number of genes controlling pigment production. Generally speaking, brown is dominant, meaning that if one parent has brown eyes and the other has blue eyes, the baby will most likely have brown eyes. But the situation is really much more complicated than that. For a more complete description, read on. \n\n\nWhat is a gene and what does it have to do with eye color?\nHumans have a diploid number of 46 chromosomes (23 pair) located in the cell nucleus. In the process called meiosis, sperm and egg cells are produced that have the haploid number (23) of chromosomes. During fertilization of the egg by the sperm the diploid number of 46 is restored. During the course of pregnancy, the fertilized egg (zygote) undergoes a complex series of changes including multiple cell divisions and differentiation of cells into the different organ systems. The result is a baby whose cells each have 46 chromosomes. One chromosome of each pair is inherited from the baby's father and the other from the mother. A gene is a length of DNA on a chromosome that does something particular for an organism. It is the basic unit of heredity, determining the observable characteristics, or phenotype, of an individual. The actual genetic makeup of an individual is referred to as its genotype. Genes are arranged in a linear fashion on the chromosome, much like beads on a string. The arrangement of genes along a chromosome is the same for both members of a chromosome pair. Therefore genes also occur in pairs. \n\n\nIf genes occur in pairs are both genes alike?\nGenes may occur in different forms called alleles so the appearance of any characteristic is dependent on the types of alleles present. A person who carries two of the same alleles is called homozygous for that gene. If two different alleles are present the person is heterozygous for that gene. In a heterozygous gene pair, one allele may be expressed over the other. The allele that is expressed is called the dominant allele. The allele that is not expressed is called the recessive allele. Dominance and recessiveness refer to which allele is expressed when the two occur together. There is nothing abnormal or defective implied in the terms. Examples of dominant/recessive inheritance are many of the famous genetic experiments conducted by Gregor Mendel. Mendel bred pea plants and found that crosses between homozygous purple flower plants and homozygous white flower plants always produced plants with purple flowers. In the process of incomplete dominance, a heterozygous gene pair produces a characteristic that is intermediate between the characteristic produced by the homozygous condition of each allele. An example of this occurs when a red snapdragon is crossed with a white one resulting in a plant with pink flowers. In a third process called codominance, the affect of each allele is expressed simultaneously. An example of codominance is the human AB blood group system in which a person with an A allele and a B allele will have type AB blood. \n\n\nI have heard that a single pair of genes determines what color my eyes are. Is this true?\nAt one time scientists thought that a single gene pair, in a dominant/recessive inheritance pattern, controlled human eye color. The allele for brown eyes was considered dominant over the allele for blue eyes. The genetic basis

I have hazel eyes and they change color anywhere from green, to green-brown, to blue.\n\nAll eye color can change over time because of age or, unfortunately, disease. \n\nEye disease is a cause of color change. So, 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, says Brian DeBroff, ophthalmology professor at Yale University. \n\nAging, however, is the usual cause of color change over time. So, yes, Emily. Color can change as we age. It does so for 10 to 15% of the normal Caucasian population. These people's eyes change slowly over many years after they reach adolescence. \n\nHow and why eye color changes - Pigment in the stroma (the connective tissue of the front layer of the iris) gives the iris color. Iris color can lighten if the number of pigment granules in the stroma decreases or if the granules produce lighter pigment. (See figure.) The iris can also lose color if the stroma pigment degrades. \n\nEyes, unlike skin and hair, do not synthesize color pigment continuously. Instead, eyes retain the pigment granules and accumulate them in the iris stroma. So, if the pigment degrades, the eye color lightens.\n\nLikewise, eyes can darken if the number of pigment granules increase or if the granules make darker pigment.\n\nThat's how the color changes. Why does it change? Genetics is the key as experimenters learned by studying twins. They observed the eyes and skin of identical twins and non-identical twins of American Caucasians between the ages of 3 months to 6 years. \n\nBoth sets of twins showed a "darkening with age of both the hair and eye colour," says Sturm. The identical twins changed color together, at essentially the same rate. The non-identical twins changed color but at different rates, which indicates a "strong genetic influence in the timing of these colour changes."\n\nEye color probably changes for the same reason we have one head instead of two: genes. Genes determine all body characteristics — including changing eye color as we 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.

Yeah I did... Makes sense too, because you're head is like 80% of its adult size by the time we are two years old, so if our ears stayed the same size from when we were children, we'd probably look a little weird if the ears and nose didn't grow with our height and what not... Hehehe... Interesting tidbit of info though...

i think they grow back but i dont think they grow longer...\nmy eyelashes have been REALLY long since i was a baby, and i think they grow for a couple years at the beginning of your life, but i dont think they just keep growing.  I do think they grow back because mine have fallen out before but i dont have any empty spaces!!

None God gave u those eyes keep um.

This may not be true for all cases but I think that as the eyes grow and mature the correction the lenses are giving the child will eveutally correct the eyes.  Not to 20/20 or to the point where they won't have to wear glasses but the point where they won't have to wear a +6.00  But it would all depend on the problem.

he University of Illinois Eye Center and other sources say a baby is born with eyes that are about 75% the size they eventually will reach by adulthood. But still other sources, including Prevent Blindness America, say a baby's eye size is about two-thirds the size of an adult eye by the age of six months. Considering how tiny a baby is, this is still a very large eye size.

As long as ur vision is not affected..\n\nCheck with ur dr for any eye disease or other medicaclcondition.\n\nthere is usually a subtle difference in the size or symmetry between the two eyes\n\nIt looks awesome. i havent seen anyone with that kind of face.

Yes, but if you change the head shape a little bit to heart and eyes to a bit rounder it would be more like a female, but do not be offended i am just suggesting. Looks don't matter, but your heart does.

Same as a humans. Theirs are simply much bigger.

If I am not mistaken it is very rare but not impossible. I have known of one little girl who is black to have blue eyes. She too is from a very mixed background. As you may know, most babies are born with blue eyes but within a week or so they Will change to green, gold, hazel etc. That little girls eyes might still turn to a blur green or something, they may not. Most black people that I know or have known have brown or green eyes but blue is not impossible.

No, they depend on weight and genetics. Basically, whatever God gave you without surgery. However, since it is made of fatty tissue, the more weight you gain, the bigger they will become.

that doesnt sound very likely....if so the doctor would say so....now its true that after 15 years some people may go blind but thats only certain people

No, it is anatomically impossible. Even the myth of mother's and teachers having eyes in the back of their head.
