Hi. I'm online and happy to answer your question today.

Dr. Rick :

The most common cause of your condition is a change in your cornea called arcus senilis

Dr. Rick :

At your age it is usually not an indication of any sort of problem however, when it occurs in younger people (30's etc) it might be an indication that their blood cholesterol levels are too high.

Dr. Rick :

Dr. Rick :

What is the take home message? There is nothing you did to cause this, there is nothing that you can take, eat or do to change this and it is nothing to worry about.

Dr. Rick :

Does this make sense to you?

will the new color eventually take over or will I always have the grey ring around the brown?
Expert:  Dr. Rick replied 5 years ago.
The gray ring will remain pretty much the same color although it may get a little thicker as the years go on. It will never become so large and wide as to take over the color of your eye or to interfere with your vision.
