Vision Problems

The Normal Eye

The eye is like a camera.  Both the camera and the eye have an opening for light to enter, a lens system to correctly focus the light and a screen upon which the image is projected.

Rays of light coming from an object enter the eye through a  transparent dome at the front of the eye. This is the cornea, which is the first lens in the system. It begins the bending or refracting of the light rays back toward a point of focus on the retina. The retina is the back of the eye upon which the image is projected. It's like the film in a camera.

Vision and Age

Over our lifetime our eyes change in many ways.

Babies eyes

Our eye color is determined by how many melanocyte pigment cells are present on our iris.  If we have many our eyes appear brown.  If their are fewer pigment cells the irises may appear blue, green or grey.   Hazel eyes are an indeterminate color - maybe dark in some areas and light in other areas.

Our babies eyes may change color.  Many baby's irises are gray at birth, and they may stay that color or they may darken over the first six to nine months of life. So gray or blue eyes can turn brown, green, or hazel, but brown eyes won't lighten and become blue.

The gene for blue eyes is recessive, meaning it does not produce a blue eye unless it's matching gene from the other parent is also for blue eyes. So even if both parents have brown eyes, they may both have a recessive blue gene and have a 25% chance of having a baby with blue eyes.  If both parents have blue eyes their is a 0% chance of having a blue eyed baby.
