The quick answer is that yours eyes don't change, but the way we see your eyes does. I said it was quick, not quick to understand. Here's what's happening. When we see something, we are really seeing light that comes from some source (a lamp, the sun, etc.) then bounces off an object and into our own eyes. There are some great tutorials on light and color at:
light and color.
Just click on a topic and an animation will be activated.
The angle we observe an object from can change the apparent color of an object. Take a glossy photograph or magazine picture and look at it from various angles. The picture doesn't change, but the way we see it does. So does the light source. Look at the ocean on different days and from different angles (on the beach, from the pier, from the hills) and you will see a similar
When different amounts and types of light (fluorescent, sunlight, etc.) hit your eyes
from different angles, or we look at your eyes
from different angles, they will seem to be
different colors. When your pupil (the hole in the middle of your eye) is more dilated (open) or constricted (closed), the color will also seem to change. Imagine you stretch a balloon out; the color will lighten as the material stretches. Dilation or constriction of your pupil will also change light angles.
Your eyes may seem to change more than your friends' eyes do if you have different pigments (colors) in your iris (the colored part of your eye).
By the time you understand why the color of your eyes seems to change, you will have learned a lot about both color and how your eyes work.
