My eyes are lighter now than they were before, is this normal?

Probably: If both eyes are a similar color, then this is probably normal for you. If the eye color is now not equal--one eye is darker than the other or has uneven color, then you should be seen for a complete eye examination.

Probaby yes: Eye color can change slightly over time, without any other problems. But if you haven't had an eye exam for more than 2 years, then it is worthwhile to see your eye md.
