People with brown eyes are found most desperate to change their eye color but it could be a very daunting change. Colored contacts do not appear the same on everyone since your own eye color plays a deciding role in settling the tone of colored lenses. EOS Natural blue are surprisingly vivid. Although they are very intricately designed, boast multiple tones; these are the blue lenses you will every find the most natural against brown eyes. They are 14.2mm so the enlargement effect is nothing overwhelming. The lenses do add a subtle illusion of bigger iris – credit goes to the limbal ring that makes your eyes appear dolly.
