Ever wondered what makes your eye colour and how its determined.

Well here are a few facts on eyes.

Colour

The colour of our eyes is determined by two factors pigmentation of the iris varie and frequency-dependence of the scattering of light. (In other words light traveling through our eyes)

Genes

Your parents determine what colour eyes you will have through these five factors. (I have included the link of the below info and a eye colour calculator.)

Homozygous And Heterozygous:
Human beings have two copies of every gene. One is inherited from the mother, and the other from the father. Homozygous means that two copies match or are dominant (denoted by two capital letters such BB) and heterozygous means that the two copies of the gene differ or recessive (denoted by two small letters, bb).

Dominant Eye Color:
Brown and green are dominant eye colors. There is 75 to 95% chance of the baby getting brown or green eyes if both the parents have same colored eyes.

Recessive Eye Color:
Blue is a recessive eye color. It’s highly unlikely for a baby to have blue eyes if both the parents have brown eyes.

Genotype:
The genotype is the gene combination for a given trait, which, in this case, is the eye color. The mother and father’s genotype will determine the eye color of the children.

Phenotype:
The phenotype is the physical appearance of the genotype, which in this case is the eye color.

Newborns

Newborns don’t produce tears. They make crying sounds, but the tears don’t start flowing until they are about 4-13 weeks old. (No wonder they never stop)

Size

Your eyeballs stay the same size from birth to death, while your nose and ears continue to grow.

Redeye

“Red eye” occurs in photos because light from the flash bounces off the back of the eye. The choroid is located behind the retina and is rich in blood vessels, which make it appear red on film.
