Ok time to write a bit more about our eyes, this week
we will start with eye colour. Our eye colour is determined by the amount of
pigment which is also called melanin is present, most dark-skinned people have
a lot of melanin thus they have darker eye colour. If someone has pale skin
their eye colour can vary from a very pale grey to blue, green or brown.
Iris colour is controlled by a single pair of genes
one we get from our mother the other from our father, the gene for brown eyes
is the dominant one so if your mum has brown eyers and your dad blue you will have
brown eyes. I have brown eyes like mum, dad had hazel eyes, like Tim he has
hazel eyes and all our girls have brown eyes like me.
Can we change our eye
colour, well first why would you want to anyway if you want to have different
colour eyes you can wear coloured contact lenses which is the most common and
reversible method. Also, eye colour can appear to shift subtly depending on lighting, makeup, or the colours
you wear.
Babies are often
born with blue or grey eyes that darken over time due to melanin development.
Some people
experience subtle changes in eye colour as they age, though it’s usually not
dramatic.
